What are the materials of the roller skin of the briquette machine? Which is more wear-resistant? As a molding equipment for pressing various materials, the briquette machining machine can meet the pressing needs of materials in different industries, but the selected roller skin does not match the required compressed material, which is easy to cause the wear of the roller skin of the briquette machining machine. The degree of wear caused by different hardness is also different, so the material selection of the roller skin of the briquette machine is very important. So what are the materials of the roller skin of the briquette machine on the market? Which is more wear-resistant? Common roller skin materials are divided into 65 manganese, 9Cr2Mo, bearing steel, etc. For different materials, the roller skins used are different, and they have their own advantages.

1. 65 manganese

65 manganese is a common cast spring steel with high hardenability, the surface decarburization tendency is smaller than silicon steel, the comprehensive mechanical properties after heat treatment are better than carbon steel, the fatigue resistance is very good, the elasticity is very good, and is quite good The plasticity and hardness of the product are at the same time low in price, which leads to its popularity, but it has overheating sensitivity and temper brittleness, so it is usually used on small-capacity briquette machinees to suppress coal powder, coke powder, charcoal powder Wait for soft materials.

2. 9 Cr 2 Mo

After strict treatment, the hardness of this alloy steel can reach HRC58-62, which has high strength and high wear resistance, and also has certain corrosion resistance. It is easy to remove the ball. This alloy steel roller skin is forged It is mainly used for medium and large-scale briquette machines with high output, which can suppress ore powder, iron powder, magnesium oxide, and laterite nickel ore.

3. Bearing steel

Bearing steel has higher hardness and wear resistance than 9 chromium 2 molybdenum, but also has uniform hardness, high elastic limit, high contact fatigue strength, necessary toughness, certain hardenability, lubricant in the atmosphere Corrosion resistance. And as a forging roller skin of the briquette machine, it is more wear-resistant than casting roller skins. It is not difficult to see that although the cost of casting roll skin 65 manganese is low, it can be replaced frequently after wear, but this non-wearing roll skin is only in disguise to increase the price of the briquette machine. The cost paid by the operator will only increase with the using time gradually increases, and the forged roller skin of the chromium-molybdenum alloy is more wear-resistant, and only a return can be paid at a time. The forged roller skin of the bearing steel has higher performance than the chromium-molybdenum alloy and can meet the long need for time.
