For equipment such as ball briquetting machines, the roller skin is one of the key components and plays an important role. The life of the roller skin determines the service time of the ball briquetting machine, and the roller skin is also a vulnerable part in the briquetting machine Therefore, when purchasing, it is extremely important to carefully check the roller skin of the briquetting machine. This can not only ensure the quality of the briquetting machine equipment, but also effectively reduce equipment costs and improve economic benefits.
The material of the roller skin of the briquetting machine is divided into 65 manganese, 9 chromium and 2 molybdenum, high chromium alloy and so on. When pressing different materials, different briquetting machine roll skins should be selected: 65 manganese roll skins are more popular and belong to steel castings with low cost. It can suppress coal powder, coke powder, charcoal powder and other materials; 9 chromium 2 molybdenum and high chromium alloy briquette machine pressure rollers are forged parts, mainly used in medium and large briquette briquetting machines with high output, and can suppress mineral powder , Iron concentrate powder, magnesium oxide powder, laterite nickel ore, etc.
Manganese 65 is a common spring steel, which has high hardenability and a lower surface decarburization tendency than silicon steel. After heat treatment, its comprehensive mechanical properties are better than carbon steel, but it has overheating sensitivity and temper brittleness. Bearing steel has high hardness, uniform hardness, high elastic limit, high contact fatigue strength, necessary toughness, certain hardenability, and corrosion resistance in atmospheric lubricants. From the above material analysis, it is not difficult to see that bearing steel as a roll skin material will be more economical and durable than 65Mn, and have a longer service life. It is a good choice for the roll skin material of equipment such as fluorite powder briquetting machines.
The roll skin is an essential and important component of the briquetting machine coal equipment. The briquetting machine roll skin determines the shape of the briquetting machine. The briquetting machine roll skin is a layer included outside the briquetting machine roll core. A cylindrical member with a ball socket on the surface. According to different assembly methods, it can be divided into one-piece type and sub-assembly type.
