Factors affecting the output of jaw crusher

The crushing force is one of the main parameters to measure the production capacity of the jaw crusher. In actual production, the crushing force is affected by many factors, which makes the crushing effect unsatisfactory. So what are the factors that affect the crushing force of the jaw crusher?

1. The mode of action on the material. Al* all rock crushing adopts mechanical crushing method. The functions of crushing machinery include crushing, splitting, breaking, grinding and impacting. For hard ore, bending and impact should be used to break; for brittle ore, bending and splitting are more favorable; for ore with er toughness and viscosity, grinding and peeling is better. The jaw crusher is mainly crushed, combined with bending, and the difference in the way it acts on the material determines the difference in crushing force.

2. The movement law of moving jaws. The trajectory distribution of each point on the moving jaw is more reasonable. Its horizontal stroke gradually decreases from * to bottom along the jaw plate surface of the moving jaw. It just meets the requirement that the amount of compression should be increased when crushing large pieces of material. The lower end of the jaw will move downwards. The staff of Red Star Heavy Industry stated that analyzing the size of the crushing force has important guiding significance for improving the crushing effect of the jaw crusher. The upper part of the trajectory is an ellipse that approximates a circle, along the crushing The cavity is downward, and the movement trajectories of each point on the moving jaw are elliptical.

3. The nature of the material. The properties of the material include viscosity, hardness, compressive strength, etc. The compressive strength of different materials is different, and the resulting crushing force is also different. Therefore, the calculation formula of the crushing force should include the parameters of the mechanical properties of the material. In addition, the particle shape of the material will also affect the crushing force of the jaw crusher.

4. The movement of the tooth plate. When the movable tooth plate moves, the force of the tooth plate is not synchronous in the upper and lower parts, and it is away from each other in some sections, the crushing force is generated by the crushing stroke, and the crushing force is not generated by the mining stroke, so the crushing force is in different intervals The size is different.
