Model:    Φ20~Φ130
Multi-alloy casting grinding ball
Brand Fengxing
Description:
     According to characteristics of wet milling in mineral processing industry, that is to mix water in the ball mill to speed up grinding ball consumption, multi-alloy grinding ball is quite suitable for mineral processing. When the grinding ball grinds with water, the grinding ball will generate “galvanic corrosion”, dramatically speed up the consumption of grinding ball. Consumption of grinding ball will not decline due to high alloy content and high hardness. Instead, it asks for high density and better tenacity. In terms of chemical composition match, multi-alloy grinding ball adds some nonmetal elements to improve density of the grinding ball. That is the also the case with slow stoning speed without water.
