What is the Best Roller Skin Surface Material of Charcoal Molding Machine

As a biochar molding equipment for pressing various materials, the charcoal briquette machine can meet the pressing needs of different industries. However, the selected roller skin does not match the material to be pressed, which can easily cause the wear of the roller skin of the charcoal briquette machine. The degree of wear caused by different hardness is also different, so the selection of the material of the biochar briquette machine roller is very important. So what are the materials of the roller skin of the ball press in YS? Which is more wear-resistant?

The common material of ball press roller skin is divided into 65 manganese, 9 chromium 2 molybdenum, bearing steel, etc. For different materials, the selected roller skin is different, and they all have their own advantages.

NO.1 65 manganese

65 manganese is a common cast spring steel, with high hardenability. And surface decarburization tendency is smaller than silicon steel. Comprehensive mechanical properties after heat treatment are better than carbon steel. Then fatigue strength is very good, excellent elasticity, and quite good. Furthermore, its plasticity and hardness and its low price, have made it more popular. But it has overheating sensitivity and temper brittleness, so it is usually used on ball presses with a small output, which can be used to press coal powder, coke powder, and charcoal powder. And other softer materials. So when you want to make small scale biochar briquette through using roller charcoal ball press machine, we will use this material.

NO.2 9 chromium 2 molybdenum

9 chromium 2 molybdenum roller material

After strict treatment, the hardness of this alloy steel can reach HRC58-62. It has high strength and high wear resistance, and at the same time has certain corrosion resistance. And it is easier to fall off the charcoal ball. Then this alloy steel roll skin belongs to forging. It is mainly used for medium and large charcoal briquetting machines with high output. So it can not only press charcoal powder, but also press mineral powder, iron fine powder, magnesium oxide, laterite nickel ore, etc.

NO.3 Bearing steel

Compared with 9 chromium 2 molybdenum, bearing steel has higher hardness and wear resistance, and also has uniform hardness, high elastic limit, high contact fatigue strength, necessary toughness, certain hardenability, and atmospheric lubricant in the corrosion resistance. Moreover, as a charcoal ball press forging roller skin, it is more wear-resistant than cast roller skins. So if you prepare to continuous biochar briquette production, we will use this material in your biochar ball press machine.
