Shearing Ledge Shredder for Recycling Plant
Areas of Application:
The shearing ledge shredder, type PUMA is used in recycling operations for the production of valuable secondary raw materials. The feed material should be available in pieces in order to be metered into the machine. To the PUMA it does not make any difference whether or not it is fed with rubber parts or plastic containers. It likes used plastic film waste and packaging material, just as much as scrap paper, cardboard container and carbon fiber waste. Anywhere where roughest conditions exist and where reliability is required, the PUMA is found in action.
Method of Operation:
The shearing ledge shredder type PUMA size reduces all cuttable material to a particle size smaller than 10 mm or coarser when required. Material is normally fed by means of a conveyor belt or vibratory feeder across the entire width of the machine. Rotating shearing elements work in combination with stationary shearing ledges to size reduce the feed material. In the lower part of the housing, a well dimensioned screen is installed, which retains the cut material in the cutter chamber until it is discharged through the screen holes. The material is then discharged straight down and transported mechanically away from the machine. The installation of an auxiliary exhaust system is recommended in most cases.
Design:
This sturdy and compactly built machine is designed for the special requirements of modern recycling operations. Excellent accessibility to the cutting chamber by means of large front doors. The upper machine housing is hydraulically opened. Rotor- and stator knives are adjusted in fixtures outside the machine and can be re-sharpened many times. The screen frame is opened hydraulically and the screen is reversible, for even usage of both sides. The massive flanged bearings are centered in the housing and the safety devices are in compliance with the current machine builders standards.
