Mining industry is developing very rapidly, crushing equipment as a special tool in the field of mining must play a very important role. The most commonly used crusher equipment in mining machinery is jaw crusher, cone crusher, impact crusher, impact crusher and mobile crusher. Crusher mainly according to your processing materials, output demand, use, etc., to decide to choose their own crushing equipment. The following small series briefly introduces several commonly used mining crushing equipment.
1, jaw crusher
Jaw crusher in the stone production line is used as the first crushing equipment (thick), crushing mode to drive JiYaXing, its working principle is the motor drive belt and pulley, make through eccentric shaft dynamic jaw movement up and down, when moving jaw rises between the bracket and fixed jaw Angle, so as to promote dynamic jaw plate to the fixed jaw close, rather than the material being crushed or broken at the same time, To achieve the purpose of fragmentation; When the moving jaw goes down, the Angle between the toggle plate and the moving jaw becomes smaller. The moving jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the broken material is discharged from the lower mouth of the crushing chamber.
2, impact crusher
Counterattack crusher work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact broken, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small into one, two, three counter repeated crushing cavity, Until the material is broken to the desired size.
3, cone crusher
Cone crusher is suitable for hard, medium hardness above the ore crushing, fine crushing. The working mode is that the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of the eccentric sleeve. The section of the moving cone close to the fixed cone becomes the crushing cavity, and the material is broken by the multiple extrusion and impact of the moving cone and the fixed cone. When the moving cone leaves the section, the part has been broken to the required particle size of the material falls under the action of its own gravity, discharged from the bottom of the cone.
4, vertical impact crusher
Vertical impact crusher is also called sand making machine, works for the material by machine upper vertical fall into a high-speed rotating impeller, under the action of centrifugal force at high speed, and the other part in the form of umbrella bypass around the impeller material to produce high speed impact and crushing, the material after crash into each other, and between the impeller and casing to form vortex repeatedly hit each other, friction material and crushing, From the lower straight discharge, the formation of closed loop multiple cycles. The equipment can make sand can be reshaped, the production of stone grain shape is excellent, a cube, needle sheet content is very low.
5, mobile crusher
Mobile crusher applicability widely, its core broken equipment can be divided into the jaw crusher, counterattack crusher, cone crusher or impact crusher, coupled with the vibrating screen, feeder, conveyor and other auxiliary equipment, a machine is equivalent to a broken production line, the vehicle configuration is flexible, there are various ways collocation, can meet the production requirements of different users.
