raw coal crushing equipment double roller crusher 8000 t/h max capacity

The working principle of this tooth roller crusher

The crusher by the motor power respectively after reducer reducer drive two teeth roll or violent backward rotation, when the material from the entrance into the body broken cavity, two teeth roll with rotating teeth material screening first, conform to the requirements of the material through teeth into the discharge chute, the big materials roller tooth tooth fracture, shear, tensile effect has been broken, from the discharging mouth eduction.

Structure and characteristics of this tooth roller crusher

1. The crusher is mainly composed of motor, torque limiting hydraulic coupler, coupling cover, reducer, coupling, tooth roller, body and other parts.

2. The crusher adopts shearing and crushing technology, which can basically eliminate the over-crushing phenomenon.Small volume and light weight, suitable for the primary, secondary and tertiary crushing system in underground, workshop and open air operation.

3. Crushing rods can be added under the box, and the crushing ratio can be increased through secondary crushing, and the discharging particle size can be adjusted.

4. The equipment is equipped with a side comb tooth plate, which can adjust the discharging granularity by adjusting the pad. The distance between the two tooth rollers and the tooth roller and the side comb tooth plate remains unchanged when working, and the discharging granularity is stable.

5. The gear plate is installed in the form of unilateral dovetail groove structure (patented by our company), which can realize the quick disassembly and reliable operation of the gear plate.

6, Electronic control using PLC control, to realize the feeding, discharging and other operation process of the equipment program control, high degree of automation.
