What is a metal crusher

A metal crusher is a machine specifically designed for crushing waste metal materials. The following is a detailed introduction to this device:

Definition and classification

Metal crushers can also be referred to as scrap metal crushers, can crushers, scrap steel crushers, paint bucket crushers, etc., depending on the type of material being crushed. These devices are universal types of metal crushers, suitable for processing different types of scrap metals.

Working principle

The working principle of metal crushers mainly relies on the impact effect. When the material enters the crusher, it will be crushed by the impact of the high-speed rotating hammer head. The crushed material obtains kinetic energy from the hammer head and rushes towards the baffle and screen inside the frame at high speed, while the materials collide with each other and are repeatedly crushed. Materials smaller than the gap between the sieve bars are discharged from the gap, while some larger materials will be crushed again by the impact, grinding, and squeezing of the hammer on the sieve until the desired particle size product is obtained.

System Characteristics

• Dry system: Dry system mainly refers to the process of separating metal and non-metal materials through an air rotary sorting system. In addition, the entire system is equipped with a dust removal device to reduce dust pollution.
• Wet system: Wet system sprays water while crushing, and performs water washing while sorting to further reduce pollution.

Advantages and Applications

• Metal crushers have the advantages of high output, low energy consumption, high efficiency, and uniform discharge of fine particles. Meanwhile, when using this device, it has low noise, no pollution, and is easy to operate and maintain. This makes metal crushers widely used in multiple fields:
• Waste metal recycling industry: Metal crushers can effectively crush waste metals (such as scrap steel, scrap iron, scrap aluminum, etc.) for further separation and processing.
• Household appliance recycling industry: Waste household appliances (such as refrigerators, washing machines, air conditioners, etc.) contain a large amount of metals, and metal crushers can break and separate these metal parts for convenient recycling.
• Aluminum and copper processing industry: Waste generated during the processing of non-ferrous metals such as aluminum and copper can also be processed through metal crushers for recycling and reuse.
• Steel metallurgy industry: In the steel production process, metal crushers are used to process scrap steel, scrap materials, etc., and reuse these materials to reduce raw material costs and increase resource utilization.
• Automotive dismantling industry: After a car is scrapped, a metal crusher can crush it and separate it into reusable metal parts, such as the body structure, engine casing, car wheels, etc.

operation and maintenance

• When using a metal crusher, the following points should be noted:
• Check the direction of rotation to ensure proper operation of the equipment.
• It is strictly prohibited to crush flammable and explosive materials to prevent accidents.
• During production, uniform feeding should be maintained to ensure the quality of crushing and normal production. At the same time, motor overload is strictly prohibited to ensure the normal operation of the machine.
• Regularly check the tightness and looseness of each part, as well as the wear of vulnerable parts. If the wear is severe, it should be replaced in a timely manner to avoid damaging the main components.
• Take necessary fire prevention measures to ensure production safety.
