Various Size Shredders
The swarf is feed into a conical hopper at the inlet at the top of shredder.
Swarf is ground down and broken up into short chips by the rotating knives. At the bottom, at the discharge side, a perforated plate is installed. Holes mesh /diameter define shredded chips length.
To prevent solid parts as shaft ends, bolts etc. from getting jammed in the shredder , it is equipped with divisible tools. If shredder knife is blocked by a solid part, shredder stops automatically and reverses. A segment at the bottom opens and the part can pass trough the opening. The shredder then automatically resume operation.
Various Size Crushers
The swarf is fed into a conical hopper at the upper part of the crusher.
In the centre of the hopper a shaft with a top-mountred feeder arm is rotating against angled cutters on the sides of the hopper.
The arm and cutters jointly feed the swarf towards the bottom of the hopper, where a crusher head rotates inside a stationary crusher ring.
The swarf is ground down and broken up into short chips by the crusher head and crusher ring. After completed crushing the chips are discharged through a chute in the frame.
To prevent solid parts as shaft ends, bolts etc. from getting jammed in the crusher, it is equipped with divisible tools. If the crusher head is blocked by a solid part, the crusher stops automatically and reverses. A segment in the crusher ring opens and the part can pass through the opening. The crusher then automatically resumes operation.
