The particle size of the waste tyre recycling machine is changed by the adjustment device, generally, there are two types of wedge and gasket.

 

The top of the wedge device is equipped with an adjustment bolt. When the adjustment bolt pulls the wedge block upward, the wedge block pushes the movable roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the output granularity becomes larger. At this time, the gap between the two wheels becomes smaller and the discharge granularity becomes smaller under the action of the compression spring.

 

The shim device adjusts the output particle size by increasing or decreasing the number or thickness of the shim. When the shim is increased, the gap between the two rollers becomes larger.
