When designing the observation doors, the ultra-fine mill not only increases the maintenance observation doors on the side, but also adopts the hydraulic open-cover device to facilitate maintenance and observation, thereby reducing downtime and increasing production output.
Long service life: The equipment introduces advanced foreign pulverizing technology to ensure the smooth operation of the whole machine. At the same time, the impact angle of materials in the crushing chamber is changed to reduce friction between materials and wear-resistant parts, thereby reducing the wear rate of parts, greatly prolonging the service life of the equipment and saving maintenance costs for enterprises.
In the jaw crusher structure, wear often occurs, especially in the lower 1/3, the wear situation is more prominent. The wear of the dynamic and static frontal plates can cause the crusher to fail to operate normally and lose the crushing ability.
There will be wear and tear in the crusher during its working process, which can be reduced and unavoidable. Wear will shorten the mechanical life, so try to reduce it. The crushing machinery also has some wear and tear in the process of processing ore. In order to minimize the loss of parts, it is necessary to adhere to the scientific selection of models, and rational use and selection of materials.
Once the type selection is inappropriate, serious conditions will result in long-term passive production in factories, and light conditions will also result in frequent multi-consumption. The crushing methods are mixed crushing and pre-screening crushing.
