How to adjust the discharge granularity of jaw crusher

Jaw crusher is a coarse crushing device, mainly used for crushing operations of stone and ore, such as river pebbles, pebbles, granite. The jaw crusher first appeared in 1858. It was first widely used in road construction and later applied to mines. It can now be used for medium-sized crushing of various ores and bulk materials. The highest compressive strength of the crushed materials is 320 MPa. It also features large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance and economical operation.

When the jaw crusher is working, the motor is used as the power. The eccentric shaft is driven by the V-belt and the sheave by the motor pulley, so that the movable cymbal reciprocates according to the predetermined trajectory, and will enter the fixed raft, the movable raft and the side guard. The material in the crushing chamber composed of the plate is broken, and the finished material is discharged through the lower discharge port. The discharge port (discharge port) can be adjusted according to user needs to obtain qualified product material size. The amount of material that the customer purchases varies from material to material, and the broken particles of the crusher are also different. So how do you adjust the discharge size?

How to adjust the discharge granularity of jaw crusher

  • 1. By adjusting the tension spring and the adjusted back wedge, the two wedges placed between the rear seat of the thrust plate and the frame are adjusted to control the size of the particles. This method is suitable for small crushers.
  • 2. Adjust the gasket, that is, put a set of gaskets between the back of the support base of the rear thrust plate and the rear wall of the frame. By increasing or decreasing the number of gaskets or changing the thickness, the purpose of adjusting the discharge port can be achieved.
