Manganese Steel Mill Liners Shipped

Recently, mill liners supplied by CAFU to a Belgian customer have been shipped to replace the original mill liners in the customer's plant.

The primary function of the mill liners is to safeguard the mill shell from the direct impact and grinding of the abrasive body and material. Therefore, it is essential that the mill liners possess excellent wear resistance.

The majority of mill liners are manufactured from metal materials, with a smaller number produced from non-metallic materials. Given the varying states of motion of the abrasive bodies within each bin, the manufacturing process for each bin liner material must be tailored to meet the specific requirements of this working condition. In the crushing bin, the grinding body plays a primary role in the impact, so the liner must have both impact resistance and wear resistance. The most commonly used liner material is high manganese steel (ZGMn13). This material offers a certain level of impact toughness and, when subjected to a certain level of impact, its surface undergoes cold hardening, resulting in a hard and wear-resistant surface. The general hardness of this material is HB300-350, and its toughness is quite high, with an impact value of up to 700 Nm/cm².

CAFU is a leading supplier of mill wear parts. We can provide a comprehensive range of materials for mill wear parts to our customers in the cement & steel slag processing enterprises. Our main materials include high manganese steel, high chromium cast iron, manganese-chromium alloy, heat-resistant steel and others.
