How Crusher Run Well?
Crusher Introduction:
The crusher can be divided into medical crusher and mining crushers. Which medical crusher is mainly used for stone crushing, general resonance stones broken, avoid surgical bring all kinds of risks; and mining crushers of various types of stone crusher and the different products according to the principle of broken particles of different sizes, divided into many models. The crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and stone industry. Commonly used crusher jaw crusher, impact crusher, vertical shaft impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher and so on.

Crusher Structure:
Take Jaw crusher for the example:
In order to make sure the crusher run well, there are some important parts in the crusher. The movement of the movable jaw is with the rod, the thrust plate bodies. When motor driven eccentric shaft through the pulley rotation, so that the connecting rod to produce motion. Up and down movement of the connecting rod to drive the thrust plate movement. Movement of the thrust plate to change the results of the tilt angle, so the movable jaw for reciprocating movement around the suspension axis, thereby crushing the ore. Eccentric shaft or spindle crusher parts, the action of a simple pendulum jaw crusher jaw suspension axis is also called mandrels. The eccentric shaft is driven by the connecting rod up and down movement of parts, because they work under a lot of crushing force, generally high-quality alloy steel. Connecting rod only simple pendulum jaw crusher have it by the rod body and the connecting rod head.
Also known as the thrust plate bracket, both parts of the movement to the movable jaw to pass, but also the safety device of the crusher. Thrust plate under pressure at work, usually made of cast iron as a whole cast, cast of two, and then rivet or bolt connection. Both ends of the thrust plate (elbow, head) wear the most serious. Order to increase the wear resistance of the elbow, head, and sometimes the elbow, head and thrust plate separate manufacturing, and the first part of the elbow should be chilled processing, but it is best to change their structure, such as rolling contact, in order to facilitate the formation of lubricant film reduce wear and tear.
Adjusting device it is broken to the size of the adjustment mechanism of the machine Pai mine mouth. As the crushing tooth plates wear, Pai mine mouth gradually increased, and the crusher product size continue to thicken. In order to ensure the requirements of the product particle size, the adjustment device to adjust the size of the port of discharge on a regular basis.
Crusher Run:
The type of jaw crusher work is dynamic compression, so its working principle is: the motor-driven belt and pulley, the movable jaw by the eccentric shaft up and down movement, when the rise of the moving jaw angle between toggle plate and moving jaw becomes larger, thus promoting the movable jaw plate close to the fixed jaw plate, its the same time the material is crushed or split pieces, broken purposes; toggle plate and moving jaw angle when moving jaw downstream smaller, movable jaw plate in the lever action of the spring to leave the fixed jaw plate and crushed material discharged from the crushing chamber mouth. With the continuous rotation of motor broken the periodic motion of mobile jaw crushing and fecal material, and mass production.
Crusher Maintenance:
Withstand during operation crusher relatively poor working conditions, torque or vibration of large and often cause transmission failure, common bearings Room, bearing bit wear, shaft keyway wear, pulley, coupling hole wear. Due to the production site dust and poor lubrication conditions, will accelerate the wear of transmission parts.
Another modern production enterprise production automation, continuous high degree of increasingly high requirements for the smooth running of the equipment. Broken equipment is towards large-scale, high-yield quantify, disassembly, transportation, maintenance difficulty is constantly increased, if there is no maintenance means more equipment in the event of rapid and effective solution, not the first time, is bound to seriously affect the production of the enterprise. Crusher so must be regularly updated and maintained to ensure the normal production of the normal operation of the machine and the enterprise.
