Scrap steel crusher plays a vital role in the scrap steel resource recycling project and has a good application development prospect.

1. Shear.

The shearing treatment is mainly for cold shearing of section steel, shafts and various large metal structural parts with a length of more than a certain size.

2. Briquetting. Also known as packing. Mainly for loose volume pipes, containers, light and thin materials, bulk materials, powders, etc. The first purpose is to reduce the volume, facilitate loading, unloading and transportation; The second is to produce high-density material blocks, which is convenient for the steelmaking process.

3. Crushing. It is to crush large pieces of scrap steel and associated appendages into small pieces or small particles to facilitate the sorting of waste. There are two types of crushing methods: mechanical crushing and physical crushing. Mechanical crushing is the use of various crushers to crush, is the most commonly used crushing method in China today.

The main crushing machinery is crocodile crusher, roll crusher, impact crusher and shear crusher. Physical crushing includes low-temperature freezing crushing, ultrasonic crushing, etc.

4. Magnetic separation. Magnetic separation is a treatment method that uses the magnetic differences of various substances in solid waste to sort in inhomogeneous magnetoacoustics. Magnetic separation is the most effective method for separating iron**. After the solid waste is fed into the magnetic separator, the magnetic particles are magnetized under the action of inhomogeneous magnetoacoustics, so that the magnetic particles are sucked into the cylinder and discharged with the cylinder into the discharge end; Non-magnetic particles remain in the waste due to the low force of the magnetic field to which they are subjected.

The magnetic field sources used in magnetic separation are generally electromagnets or permanent magnets.

5. Cleaning. Cleaning is to use a variety of different chemical solvents or hot surfactants to remove oil, rust, sediment, etc. on the surface of steel parts. It is commonly used to treat engines, bearings, gears, etc. contaminated by cutting oil, grease, oil or other buildup in large quantities.

6. Preheating. Scrap steel is often cohesive with contaminants such as oil and grease, which do not evaporate immediately and can contaminate the molten metal. When steel scrap is stored in the open air, it can contaminate the molten metal due to moisture and other greases and oils. After the scrap steel stored in the open air is damp, due to the inclusion of moisture and other grease and other easily vaporized materials, it will quickly expand in the furnace due to the explosion, and it is not suitable to be added to the steelmaking furnace.

For this reason, many steel mills use the method of preheating scrap, using a flame to bake the scrap directly, burn off the water and grease, and then put it into the steel furnace. In the metal preheating system, there are two main problems that need to be solved: first, incomplete combustion of grease can produce a large number of hydrocarbons, which will cause air pollution and must be solved; Second, due to the different sizes and thicknesses of the scrap on the conveyor belt, the preheating and combustion are uneven, and the contaminants on the scrap sometimes cannot be thoroughly cleaned.

It is also used in the crop cleaning industryMagnetic separatorThe magnetic separator, also known as the magnetic separation and soil removal machine, is an indispensable part of the crop cleaning equipment by using strong magnetism to separate the soil blocks in the crops.
