1. Dihai scrap crusher quality is very good, about 30 tons of scrap crusher is a large equipment.
2. Huahong's machine is very expensive and difficult to use. It is proced by many manufacturers with 15-20 tons
3. 1. Shear
the shear treatment is mainly used for cold shear of section steel, shaft and various large metal structural parts with length exceeding a certain size
2, briquetting
is also called packing. Mainly for the loose volume of pipes, containers, lightweight materials, granular materials, powder and so on. The first purpose is to rece the volume and facilitate loading, unloading and transportation; The other is to make high density material block, which is convenient for steelmaking process
3, crushing
is to crush large pieces of scrap iron and steel and associated accessories into small pieces or small particles to facilitate waste separation. There are two ways of crushing: mechanical crushing and physical crushing. Mechanical crushing is the most commonly used crushing method in China. The main crushing machines are crocodile crusher, roller crusher, impact crusher and shear crusher. Physical crushing includes low temperature freezing crushing, ultrasonic crushing and so on
4, magnetic separation
magnetic separation is a kind of processing method which uses the magnetic difference of various substances in solid waste to carry out separation in uneven magnetic sound. Magnetic separation is the most effective method to separate iron-based metals. After the solid waste is fed into the magnetic separator, the magnetic particles are magnetized under the action of non-uniform Magnetoacoustic, so they are attracted by the magnetic field, and the magnetic particles are sucked into the cylinder and discharged with the cylinder into the discharge end; The non-magnetic particles remain in the waste e to the small force of magnetic field. The magnetic field source used in magnetic separation is usually electromagnet or permanent magnet
5, cleaning
cleaning is to use various chemical solvents or hot surfactants to remove oil, rust, sediment, etc. from the surface of steel parts. It is often used to deal with engines, bearings and gears polluted by cutting oil, grease, oil or other attachments
6, preheating
scrap steel is often contaminated with oil and grease, and the grease and oil that cannot be evaporated immediately will pollute the molten metal. After the scrap stored in open air is damped, the molten metal will be polluted e to the inclusion of water and other grease and oil. The waste steel stored in the open air will expand rapidly in the furnace e to cracking e to moisture and other easily vaporized materials such as grease, and it is not suitable to be added into the steel-making furnace. For this reason, many steel plants use the method of preheating scrap, using the flame to directly bake the scrap, burn the water and grease, and then put into the steel furnace. In the metal preheating system, there are two main problems to be solved: first, incomplete combustion of grease can proce a large number of hydrocarbons, which will cause air pollution; Second, e to the different sizes and thicknesses of the scrap on the conveyor belt, the preheating and combustion are not uniform, and sometimes the pollutants on the scrap can not be thoroughly cleaned.

4. Scrap crusher is a relatively mature metal crushing equipment, the blade is made of alloy steel, which is the hardest material on the market.
5.
Scrap crusher is a kind of crushing machine used to proce scrap materials, which is mainly used to scrap cars, household appliances and light steel scrap
6. Scrap crusher is not only powerful, but also widely used. There are many kinds of materials that can be broken. For example, high-strength materials such as waste steel, car shell, electric car and motorcycle shelf, and general materials such as iron barrels, cans and computer related parts can be broken in batches. So there is a universal scrap crusher.
7. In the proction line of scrap metal crushing, scrap crusher is one of the main equipment. The crusher is mainly used to crush the light and thin metal plate into small pieces, such as the waste car body, which is easy to separate and get the purer ferrous metal raw materials. At the same time, the scrap metal broken by the crusher is also easy to transport and return to the furnace. The structure and working principle of the crusher are explained in detail through graphic driving
the structure of the crusher is shown in the figure, the hammer head is hinged on the hammer disc with the hammer shaft, and the hammer disc is assembled on the main shaft. The working principle of the crusher is to impact the material with a high-speed rotating hammer. Because the impact time between the crusher hammer and the material is very short, it will proce a great impact force, so that the material will be broken along the natural cracks, bedding planes, joint planes and other vulnerable parts. When the hammer strikes the sheet metal, the shear stress proced at the magnetic impact point e to the impact force is greater than the shear strength limit, the material will shear failure, and the hammer will tear it into small pieces along the shear seam, and bring it into the cavity between the rotor and the liner. During the rotation of the main shaft of the crusher, the hammer constantly knocks the material in the cavity.

According to the current scrap price, if you find a good market, it is no problem that the scrap crusher can make more than 100000 yuan a year< br />
10. Dust explosion. In the process of crushing materials, it is inevitable to proce some st. Once the st concentration reaches the concentration of explosion, it will explode when meeting Mars. The previous explosion in Kunshan, Jiangsu Province is a manifestation of this phenomenon.
