Sand making machine is also called impact crusher. SBM combined with the actual situation of domestic sand making production, developed high efficiency and high quality crushing equipment with domestic and international leading level. VSI Crusher can not only provide high-quality aggregates for highways, railways, high-rise buildings, municipal engineering, hydropower dam construction, port terminals, concrete mixing plants, etc., but also become more and more metal ore crushing, quartz sand production , The mainstream equipment in the fields of steel slag processing, etc., so it has undoubtedly become the core equipment in the field of machine-made sand and stone shaping.
The characteristics of SBM sand making machine, the sieve plate adopts a unique spring retreat mechanism, which is convenient, reasonable, safe and reliable. HXVSI series high-efficiency vertical shaft impact crusher (sand making machine) adopts spring constant force adjustment to make the crushing force constant for a long time. Maintenance is simple, just lift the upper box and open the lower box, so maintenance is extremely convenient. The multi-layer three-channel discharge device is adopted to discharge the materials that meet the requirements in time, extend the life of the wearing parts, and greatly increase the output of the table. The rigid solid rotor body is used, which has large rotating inertia and strong striking force, which is not easy to cause equipment jams. With plastic function, the product has a square shape and a large packing density. The equipment is small in size, easy to operate, and easy to install and maintain. While the output is high, the energy consumption is small and the crushing ratio is large.
The working principle of the SBM sand making machine. During the work of the sand making machine, the material enters the machine from the feed hopper, and the material is divided into two parts through the distributor, and a part enters the high-speed rotating impeller from the middle of the distributor. The interior is rapidly accelerated, and its acceleration can reach hundreds of times the acceleration of gravity. Then it is ejected from the three uniformly distributed flow channels of the impeller at a speed of 60-70m / s, and first impacts with a part of the material that has fallen from the surrounding of the distributor Crushed, and then impacted on the material lining in the vortex branch cavity together, rebounded by the material lining, impacted diagonally upward on the top of the vortex cavity, and changed its direction of movement, deflecting downward movement, the material emitted from the impeller flow Form a continuous material curtain. In this way, a piece of material is subjected to two or more chances of impact, friction, grinding and crushing in the vortex crushing chamber, and the material that is crushed later is discharged through the lower discharge port.
