The portable crusher plant has reasonable bearing structure and quick installation. Simply handling the supporting parts, the mobile crusher can be put into operation immediately. If the operation is needed, it can be easily dismantled and transported without any residual loss. The portable crusher plant is mainly used for the processing of materials such as metallurgy, chemical, building materials, hydropower and so on, especially for the broken and sieving operation of the flow stone, such as expressway, railway and hydroelectric engineering. Users can adopt various configurations according to the type, size and material requirements of finished raw materials. In recent years, it has made outstanding contributions to the construction waste resource re-use project.
The integrated set of units reduces the requirements for the site infrastructure and the difficulty of the installation of auxiliary facilities, saving a large amount of infrastructure and relocation costs. It can break the material in situ and move along with the advancing surface of the raw material, thus greatly reducing the transportation cost of the material. Truly provide customers with efficient, low-cost project operation hardware facilities.
The material is transported to the crusher evenly through the feeder. After the crusher is preliminarily broken, the closed circuit system is formed through the circular vibrating screen to realize the recycling of the material. The finished material is output by the conveyor, and the continuous crushing operation is carried out. The jaw type mobile crusher can remove the circular vibrating screen according to the actual production needs, and realize the initial crushing of the material. It is convenient and flexible to operate with other crushing equipment.
Sand making machine is to the present state of our natural sand resources is scarce in the specially developed type finely crushing equipment, sand making machine is mainly used for artificial mechanism of sand production, it not only solved due to lack of the natural resource of the yellow sand and gravel aggregate supply, the price soaring, but also can make use of waste concrete, waste lime and other waste sand preparation mechanism, not only the cost is low, making sand and has higher environmental benefits.
Wear less and wear well In the process of sand making machine production, stone can protect the underlying formation, the material to impact between broken, not direct contact with metal components, but the lining with material shattered by shock, friction, reduce the wear and tear of the equipment and its parts.
Significant energy saving and low production cost Sand making machine can according to the requirements of the material nature or broken to varying degrees of broken material, for the user to reduce a lot of unnecessary energy consumption, and small application passes through the device again after crushing processing can become a qualified application, can be directly for the use, no other devices for secondary processing work, for the user to save a large amount of investment cost.

Jaw crusher, impact crusher and hammer crusher are all the stone crusher commonly used in ore crushing, and some problems may arise during the use of stone crusher. Today, you are here to talk about the noise problems that the new stone crusher that has been bought by the user is consulting in the crushing process. Why will the new stone crusher have a noise problem in the use of the crusher?
According to the research of our company technical personnel, it is found that the cause of the cause of the noise of the crusher is two: one is to start the noise, and the two is the noise of operation; the noise in which the starting noise is usually refers to the noise caused by the starting process of the equipment, and the noise is generally large, and it is mainly made by the motor, for this kind of noise. Noise can only be reduced as far as possible. Theoretically speaking, it is unavoidable and improper operation will cause the noise problem of stone crusher to increase.
The noise of the stone crusher and the noise in operation is caused by the improper design of the equipment. Because of the unreasonable design of its structure, the noise will come out in the actual production process. For this kind of noise, the first thing we think about is to lubricate the noise emitted by the noise. The sample can effectively reduce the noise problem of stone crusher.
The main reason for the noise of the stone crusher is that the user can correctly handle the noise of the stone crusher according to the cause of the noise of the stone crusher. In the process of purchasing the stone crusher equipment, the user selects the motor with excellent performance and low power consumption, and it is best to do field debugging at the factory site to see if the noise is relatively large.
Wheel-Type mobile crushing station is a kind of commonly used equipment, in the gravel production, compared with traditional device, the significant characteristic of Mobile Crusher is mobile performance is different, can be very good to break the limitation of space, with the advantages of more, here is to introduce in detail, the machine in what are the advantages in the gravel production problems.
1. Strong mobility and integration of the whole set. Mobile crusher length is short, the different crushing equipment respectively independent of installed in mobile chassis, short wheelbase, small turning radius, flexible in ordinary highway and areas, the integration of the equipment installation form, eliminates the fission components and complex site infrastructure installation work, cut down the consumption of materials, working hours, and compact unit and reasonable space layout, improve the flexibility of ground based;
2. The operating function is directly effective and flexible. Wheel-Type Mobile crusher of integration can be used independently, can also according to customer the types of materials in the process, product requirements, providing a more flexible process configuration, meet the various requirements of users of mobile crushing, mobile screen classification, make production organization, logistics, transport more directly, greatly reduce the production inputs, the machine can not only according to the requirements of the different crushing process of "broken after the first screen", also can form "screen before breaking" process, also can be combined according to the actual demand into coarse crushing, finely crushing screening system, two pieces can be combined into coarse crushing, crusher, finely three stage crushing screening system, still can run independently, there is a great deal of flexibility, To meet more production needs;
3. High production capacity and low power consumption. Wheel-Type Mobile crusher in gravel production line, the host by motor, v-belt drive main shaft, so that the internal parts of equipment operation, large chunks of material from the inlet into the crushing cavity, was break, high-speed movement of the parts in the process, material after broken loop, product quality is good, and it has large capacity, power consumption is low in production.
In order to meet the needs of different industries and different scale of production, the portable crusher plant not only needs different configurations, but also needs different types. The external shape refers to its volume. Generally speaking, it can be divided into large and medium size, and the different foreign price is different because of the technology and production cost for its input. Different, we are here to introduce small and medium-sized crushing station price quotes related issues.
There are many factors that affect the price of small and medium-sized Mobile crushers.
1. Compared with foreign trade import equipment, domestic and small scale portable crusher, whether in production and manufacturing cost input, or in additional cost input, such as import and export tax, equipment transfer fee, are all less than foreign trade import equipment, moreover, the position of the domestic medium and small breakage station is also based on the existing country. The internal economy and the level of consumption control it, so overall, the price of domestic crushing stations is still worth considering.
2. compared to large and super large equipment, the price of small and medium size portable crusher plant is certain to be relatively favorable. After all, it is sure that the small and medium crushing stations are far less than large and super large in terms of the input of raw materials, the time of production and the consumption of labor and so on. The price is still worth looking forward to.
3. Compared with the previous broken production technology, the existing production technology of the existing portable crusher has been greatly improved. Then, the production cost of the original medium and small crusher station is greatly compressed, so the reduction of the cost will also reduce the price, in addition, it is also due to the lack of the current enterprise. The sharp increase, the fierce competition of the peers will also make the price of the current market tend to be more and more common, so in general, the price of small and medium small mobile breakage stations is more suitable for most of the enterprise users to invest.
The article mainly introduces the analysis of the price of small and medium mobile breakage station. According to the current situation of our country, the price of the crushing station is analyzed from three aspects. The price is the factor that can not be ignored when the equipment is selected and purchased, because it is related to the cost of the customer, so the analysis of the price is the comparison.
For a complete machine-made sand production line, different types of equipment will play different roles in sand production. In order to meet the product demand of the mechanism sand production line, it is necessary to select the sand making machine with plastic function, such as the VSI series sand maker, vsi5x, vsi6x and so on. When the machine is used, the machine is mainly processed after the fine-grained material is processed, and the sand making process is completed, so as to obtain the better grain product.
After analyzing the function of the sand making machine in the mechanism sand production line, we will give a detailed description of the links contained in the production process, which are mainly rough break, medium sieving, fine-grained screening and cleaning and removing impurities, and the equipment required for different links is different. These links are analyzed.
1. coarsely, this link is the processing link of the material in the mechanism sand production line. The general mining material is delivered to the jaw crusher by the feeder evenly and crushed to the required granularity, and the belt conveyer is sent to the next broken link after the grain size. The analysis can see that the equipment needed in this production link is jaw crusher. According to different needs, different types of equipment can be selected.
2. medium and broken screening, this is in the mechanism sand production line is located in the processing link after the coarse crushing, the coarse crushed stone particles are sent to the cone crusher or the counter crusher to be crushed by the belt conveyor. The grain size is sent to the circular vibrating screen to be sieved. The size of the particle size satisfies the requirements to the next link and does not meet the required back cones. Crusher or counter crusher continues to break, this link is circulate, can guarantee the uniformity of the finished product particles, and the link needs to select taper or reverse type or model, is also based on production needs.
3. fine crushing and screening, generally speaking, the link in the mechanism sand production line is mainly in the middle of the position, the equipment needed to be used in this link is the sand machine we mentioned, the machine is fine and plastic for the material after the broken, and the round vibrating screen is sieved after fine crushing, and the size of the machine is properly sent to the next ring. Section, is not suitable to be returned to the sand making machine to continue to crush, this cycle processing process is also to guarantee the finished product particle uniformity.
4. cleaning and removing impurities, this link is generally out of the end of the whole process of the whole mechanism sand production line process. The qualified sand and stone particles in front of the process are sent to the washing machine for cleaning and removing impurities. After the cleaning, the sand stone is dehydrated and dried to be the finished product we need.
The article mainly introduces the effect of sand making machine in the production line of mechanism sand. It not only introduces its specific function in detail - making sand and shaping, but also analyzes the general contents of the four stages contained in the production process. In this production process, the equipment can be configured according to the different production requirements and is more flexible.
Because of the market demand, there are more and more manufacturers of sand making machine, but not every manufacturer can produce qualified equipment. The quality of sand making machine provided by these different manufacturers has a certain gap, which makes its own development also greatly affected, so stone What conditions should the producers of sand making machines have to produce the equipment?
Before the stone sand maker machine came out, coal was solved by incineration. It has a great pollution to the environment. Since the equipment has been reduced, it has reduced environmental pollution, so its demand is large and the production and production are more and more. But some of these manufacturers are regular large manufacturers, and some are small manufacturers. The difference is not only on the scale of the factory, but also in the production strength of the factory. The technical gap makes the sand making machine have a big gap in the performance of the production and so on, and the benefit of the production project is different.
Therefore, the manufacturer must have a certain production strength to produce qualified equipment and be technically innovative rather than imitating, otherwise it will cause inferior products to users, which not only affects the problem of worsening environmental pollution, but the equipment produced by such manufacturers is at the price. It has a relatively low advantage to make its sale better, which has a great obstacle to the development of the sand making machine in China. So it is necessary to strictly demand the strength of the production entrepreneurs and the technical level to produce the stone equipment.
One point is that the manufacturer of sand making machine should have a certain service consciousness. In this way, the problems that can not be solved in the future production process can help the customers to solve the better production of the equipment, but also give the customer a good impression and help the sale of the equipment.
The above article is mainly about the sand making machine manufacturers should have what conditions, from the above introduction can be seen that only technical, service are better manufacturers can be farther, can make better development of stone sand and stone equipment.
For the open quarry production, in the case of meeting the production demand, choosing different equipment can obtain different production effects and different production benefits. Therefore, the selection of equipment is very important. One of the equipment used in the current market is the portable crusher plant, which is made up of many production machines. This portable crusher has better mobility and is more conducive to quarrying production. Here is an introduction to the advantages of this production process.
First, the advantages brought by portable crusher plant to open quarrying. 1. all the parts of the portable crusher plant are installed on the independent movable chassis with short wheelbase and small turning radius, which can be used flexibly and unrestricted in the ordinary road or in the bad mountainous area. Advantages of portable crusher plant to open quarrying
2. Different from the ordinary crusher, the portable crusher plant is more focused on the installation of the integrated unit, which can not only eliminate the installation of the complex site infrastructure, reduce the consumption of material and time, but also improve the flexibility of the location of the site.
3. the portable crusher plant can break the scene in depth without the aid of external force, complete the field breaking work of the material, and move with the advance of the raw material mining surface, so that the transportation cost of the material can be reduced.
Analysis of the production process of a portable crusher plant As a large joint crushing machine composed of multiple machines, the material is transported to the crusher evenly and the material is transported to the crusher by the feeder. The portable jaw crusher is broken through a circular vibrating screen to realize the circulation breakage of the material. The material is output by the conveyor and continuously broken.

The Raymond mill working principle whole structureis composed of a host machine, analysis, plumbing, air blower, according to the needs of the user can be equipped with crushing machine, hoisting machine, electromagnetic vibration feeder, electric motor etc..
Matters needing attention in Raymond mill operation: 1. the Raymond Mill powder machine is normal, should make the equipment safe operation of equipment maintenance system to ensure the long-term safe operation of Raymond mill, and the necessary maintenance tools and grease and corresponding accessories.
2. Raymond mill grinding roller device for more than 500 hours to replace the roller using time, the rolling bearing of roller sleeve must be cleaned, the damaged parts should be replaced, refueling tools available manual pumps and the grease gun.
3. Raymond Mill in the use of the process, there should be fixed personnel responsible for custody, operators must have a certain level of technology. Raymond mill before the installation of the operator must carry out the necessary technical training, so that the understanding of Raymond Mill principle, performance, familiar with the operating procedures.
4. Raymond mill after a period of time, should be carried out maintenance. At the same time repair replacement treatment on roller grinding ring blade wearing parts, grinding roller device to examine connecting bolts and nuts should be before and after use, to see whether there is loose, grease is full.
Due to the recent China's construction, water conservancy and other aspects of the construction, increase the demand of domestic sand, sand industry very influential; rise sand industry, the mining machinery industry of sand making machine, processing equipment and technological process of research and improvement. As an important part of sand and gravel production line, sand making machine is very important for its stability and durability because of its important position in the production of manufactured sand.
The mechanism of sand production line can not only provide high-quality aggregate for highway, railway, high-rise buildings, municipal engineering, hydropower dam construction, port, concrete mixing station, and increasingly become the main stream of production equipment of metal ore, quartz sand, slag processing and other fields, has become the core mechanism of sand and stone plastic industry field the.
Technological process
First of all, the material into the jaw crusher preliminary broken; secondly, the coarse material produced by belt conveyor to the crushing machine for further broken, then after crushing sandstone vibrating sieve into two kinds of gravel, sand sand mechanism to meet the feed size of sand making machine, another part of the material to return again into fine broken.
Part of the sand machine's material is made into sand, washed by sand washing machine (optional) and made into finished sand. The other part of the machine is broken again, and the final output of all kinds of machine-made sand meets the requirements.
Process characteristics
1. the product is cubic, strong and excellent, with low content and strong compression capacity, which is suitable for high standard construction, such as water conservancy, bridges, highways and high-rise building industries.
2. the mechanism of sand production line is suitable for granite, Xuan Wuyan, river gravel, aluminum, cement clinker, quartz stone, Jin Gang sand, sand, iron ore and other raw materials are broken, the traditional customer service mechanism of sand production equipment is only applicable to soft material crushing shortcomings.
As one of the important basic materials in the construction industry, sand and gravel will contribute to the construction of China. As a manufacturing machine for sand and gravel, the sand maker machine provides sufficient raw materials for the building. Now, the development of the mine concrete and construction industry is very rapid, which has added power to the sand and stone industry. Natural sand is now unable to meet the demand of the market, and it needs mechanism sand to help its development. The mechanism of sand compared with natural sand, the availability of more, especially in the building construction, it shows a great advantage.
Because of the demand of the market, the important position of the sand and stone industry is not to be underestimated. However, with the rapid development of China's economy, at present, there are many problems in the sand and stone market. We need to pay attention to it.
First, the scale of sand making enterprises is small. There is a lot of demand for the mechanism sand, but the market is obviously not able to meet the demand for use, which needs to be improved. The management level of many manufacturers is low. Many system sand making machine manufacturers now unexpectedly also depend on the nature of mining, this model of development is very terrible, because of the limited resources, it makes the development of these manufacturers limited.
Second, the means of mining are relatively backward. Now is the high-tech era, and the advanced production technology is productivity. If we want to get a high level of production and productivity, we must increase our efforts in importing the machine. Moreover, the mechanization and automation level of the sand making industry is relatively low, which brings trouble to the development of the factory.
In view of this, the manufacturing enterprises of sand making equipment have a lot of space to develop, because the demand for users is growing rapidly in the future. At this time, the sand making machine manufacturing enterprises should develop steadily, ensure the quality of the machine, let users have no worries, and guide the enterprises to develop in the right direction.
Third, in order to develop more long, the production standards of sand making enterprises should be more perfect. Relative to other industries, the policy and planning of sand and stone are less, and some of the policies and relevant regulations are relatively backward. So, this requires the workers in the industry to work harder to prepare for the standardization of the sand machine.
In industrial production is mainly composed of a feed hopper, the material screening machine, vortex dynamic crushing cavity, an impeller and a bearing and a transmission shaft parts. The motor is the sand making machine for production and sand heart, drive shaft and bearing plays a role of transmission power, the distributor is an important component of material separation material in breaking and grinding, and the impeller and the vortex dynamic crushing cavity is the main material for broken, then we on the sand machine of the various parts of a brief analysis function:
1, a feed hopper hopper sand making machine is usually a cylinder body device material part, it has a very good wear resistance, installed to prevent wear rings, no broken material to its strong friction, hopper is material from the feed device to the crusher for an important transition device is broken.
2, the material screening device material sieving device is a structure after some crushing the material in sand making machine for material screening, it is mainly used as the material damage after a part has reached the standard of materials will be broken by material sieving device sent sand making machine, and the other part is not the setting the size requirements of the material will be in the material screening device into the crushing chamber under the action of two broken, finally achieve the qualified material size.
3, eddy broken cavity which is an annular space composed of two cylinder, through the impeller in the crusher internal high-speed rotation of material form a striking and friction.
4, The impeller, the impeller sand making machine is mainly made of a special material, are arranged between the two bearings, the height of rotation will enter into the impeller center material evenly divided over the various parts, such a powerful impact crushing.
5, bearing and gear bearing is a device on the impeller and crushing device to drive action by the motor and the triangle belt, bearing the main spindle, bearings and bearing seat.
6, the base seat is generally four edge shape, the central position of bearing, both sides is discharging device, the motor in the vertical position.
7, Parts of the lubrication, the lubrication system of sand making machine in the operation of the main bearing parts, usually on bearing lubrication oil to add specific pump.
