coal roller crusher 1.Crushing coarse, medium, fine material. 2.Alloy steel shaft 3.Teeth-roller is replaced quickly

Working principle of double teeth roller crusher 

2PLF Series grading teeth-roller industrial crusher is widely used for 1st stage crushing,2nd stage crushing and 3rd crushing in the crushing system in pit, workshop and openwork, This teeth-roller crusher is driven by electromotor via reducer, making two teeth-rollers rotate inward synchronously in opposite direction. After material dropping from the inlet to crushing chamber, it will be firstly classified, those which are accepted will enter into outlet chute through teeth-roller spacing, then other massive materials are crushed through breaking, cutting, stretching between two teeth-rollers, and then discharge from outlet opening.

Structure of double teeth-roller crusher 

 

1.Modular ribbed robust machine

2.electromotor

3.Torque-limit fluid coupling-----allows loaded startup and affords torque protection to the machine.

4.connection cover

5.Teeth-roller-----unique designs to allow maximum utilization of the material. Sizer teeth can be replaced quickly.

6.shaft----- high strength alloys steel shaft

7.Shaft coupling

8.Overload protective device ----- robust modular gearbox with high torque capacity.

Application: coal, coal gangue, iron ore, iron gold, coke, slag, sandstone, limestone, shale, rock etc.

We can also design a complete of production line------crusher, belt conveyor, bucket elevator, vibrating feeder, vibrating screen etc
