Thin mill liners use a short time, near a large investment and replace fan trouble, too thick mill liner cycle longer, but lining their own weight to the ball mill to bring heavy, thick liner occupancy the warehouse half white ball mill liner volume, reducing the warehouse area mill, grinding material cavity becomes smaller, the corresponding efficiency is low, how to configure the mill liner is more appropriate? Zhengzhou Jinyang Machinery tell you based on years of experience under normal circumstances is a replacement liner period a year better, the thickness of the best maintained at about 6 cm. Chemical composition of high wear resistance of the alloy layer of carbon content of 4-5% mill liner, chromium content of up to 25 to 30%, the microstructure in Cr7C3 carbide volume fraction of 50% or more, the macro hardness HRC56 ~ 62, chromium carbide hardness HV1400 ~ 1800 wet grinder liner, higher than the hardness of quartz sand HV800 ~ 1200. Carbide wear due to the direction perpendicular to the distribution, even in comparison with the same cast alloy composition and hardness, wear resistance more than doubled.
