Metal shredder

Metal shredder, also known as dual axis crusher, is a new type of shear crusher. It is mainly used as a metal coarse crushing equipment for crushing and processing large waste and empty materials such as scrapped car shells, colored steel tiles, paint barrels, etc. The processed materials are in granular or sheet structure according to their thickness and material type. Compared to metal crushers, this machine has the advantages of low noise, less dust, and wide applicability The advantage of a large crushing ratio. In terms of equipment applicability, metal shredders are mainly used as primary crushing equipment in front of metal crushers for pre-treatment of large metals that cannot be crushed by metal crushers, which has met the requirements of fine crushing processing equipment. In terms of equipment composition, the metal shredder mainly consists of a shredding blade group, a bearing box, a box bracket, a feeding system, a power system, and an electrical control system. The unique power protection mechanism of the machine can effectively prevent equipment damage caused by overloading during the crushing of large waste metal.

Principle and characteristics

Metal shredders are commonly used in equipment production design, including dual axis metal shredders and four axis metal shredders. During operation, the machine stably transmits power to the main shaft through a reducer connected to the motor. Under the traction of the main shaft, the shredder blades fixed on the main shaft clamp the waste metal entering the metal shredder cavity. During the continuous pressing process of the blade clamping position, the material is drawn into the gap between the two shafts, Through the dual axis tearing effect, the material achieves a crushing effect. After crushing, the material usually appears in a strip or sheet shape, filtered out from the bottom of the equipment, transported by a conveyor belt, and enters the material for centralized processing or direct collection by other equipment. Composition of metal shredder:

1. Special dynamic and fixed blades for metal shredders

The shredder blades are divided into fixed and moving blades, which are fixed on the shredder spindle through internal hexagonal clamping holes to crush and process materials.

2. Metal shredder spindle

The hexagonal interface shaft is connected to the reducer through bearings and couplings.

3. Metal shredder chassis

It mainly provides support for the installation of bearings and the fixation of the main shaft, while also providing a relatively enclosed space for the linkage crushing of four or two shafts.

4. Metal shredder bearings

Reduce the friction force during the spindle rotation process through internal pressure cylinders, thereby reducing torque loss.

5. Reducer

Adjust the motor output speed through the reducer, while reducing motor damage caused by spindle impact and increasing spindle torque.

5. Control and other accessories such as support frame, main body, motor, hopper, distribution cabinet, electromagnetic directional valve, etc.
