The crusher is a machine that crushes large-sized solid raw materials to the required size. The crusher is composed of coarse crushing, fine crushing and wind conveying devices, and achieves the purpose of the crusher in the form of rapid impact. The use of wind energy to produce secondary powder eliminates the traditional screening process. Mainly used in mining, building materials and other industries.
Main classification
According to the D90 standard of the required material fineness, 90% of the material reaching the predetermined fineness can be divided into crusher below 60 mesh, crusher 60-120 mesh, fine mill 120-300 mesh, and micro mill more than 300 mesh.
There are four kinds of external forces applied to the material in the crushing process: rolling, shearing, impact and grinding. Press rolling is mainly used in coarse and medium crushing for the crushing of hard materials and bulk materials shear is mainly used in crushing or crushing for toughness or fiber materials crushing impact is mainly used in crushing and depolymerization for brittle materials crushing grinding is mainly used in fine crushing and micro crushing after medium fineness crushing.
Scope of application
The equipment with higher output under the premise of the same grinding fineness is mainly suitable for the grinding and processing of mineral products materials in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower, refractory materials, steel and other industries.
The equipment with lower output under the premise of the same grinding fineness is mainly suitable for the material crushing treatment of food, chemical, medicine, greening, sanitation, and other industries.
Coarse crusher is mainly used in various industries of crushing pretreatment operations, its role is mainly to process the larger diameter of the material 5-10cm to the smaller diameter of the granular material diameter of 5-10mm.
The crusher is mainly used for medium fineness grinding operations in various industries. Its role is to process granular materials to medium fineness powders with required diameters for subsequent treatment or as finished products.
Micropulverizer is mainly used in most industries for micropulverization operations that will be pulverized
After the material is crushed again to achieve the required diameter of the material is mainly used for raw material processing of the product
Operation and use
1. After unpacking the box, carefully check whether the equipment is damaged during transportation, and then put the electrical control device of the machine and auxiliary machine in place, and then connect the pipe road of the main and auxiliary machine. When assembling the flange of each pipe entrance, the seal must be coated with "iron anchor 609" liquid sealant to ensure the tightness of the pipe. To avoid electrostatic sparks caused by dust explosion.
2, before the trial operation of each single machine, it is necessary to check whether there are metal items in the machine, if there are excluded. Whether the bolts are firm, the tightness of the belt, the reliability of the protective cover, and so on.
3, in the following order to start the motor, close the damper to start, crusher -> dust collector -> sub-device -> screw feeder -> Open the damper -> air closers.
4. After the empty car runs for five minutes, the operator should carefully observe the various instruments on the control cabinet, and wait for the no-load power to be stable before feeding. After feeding, it is not allowed to overshoot the rated value of 32.6A, otherwise the feed amount should be reduced to ensure that the normal operation of the discharge motor can work regularly.
5, can be stopped in the following order
Screw feeder -> After five minutes of operation can be stopped with the grinding machine, dust collector, separator -> air closers.
6, no variable speed handle of the control divider, can change the speed of the divider, while achieving the fine adjustment products. If the particle size of the product is required, the speed can be raised, and the speed can be reduced to increase the particle size.
