A heavy duty shredder machine is designed for grinding rubber goods, car tires, wooden bars, boards, pieces of chipboard, fiberboard, cardboard, paper, plastic containers and all possible bulky waste.
Waste is crushed by multiple cutting discs with specially shaped teeth, located on two parallel shafts, rotating in different directions at low speed.
The operation of the Heavy-duty Shredder is controlled by the SIEMENS LOGO! PLC controller. When one of the rotors stops during operation due to the material being bitten by the rotors, the reverse is automatically turned on for a set period of time, then forward rotation is turned on.
The material is shredded by two specially shaped rotors rotating towards each other at low speed. The rotor consists of a splined shaft with circular knives mounted on it.
The material of the chopper knives is high-quality tool alloy steel 42CrMo with high hardness, strength, wear resistance, which has undergone heat treatment.
Knives double – are established in couple, everyone 20 mm thick. After blunting the corner edge of the knives, the knives are swapped, which doubles the service life of the knives.
