Cr8%-Cr18% Grinding Section Forged Grinding Media Balls For Mill

Product Description

Grinding sections are specialized components used in autogenous (AG) mills, semi-autogenous (SAG) mills, and other types of grinding mills. These sections are typically composed of a combination of grinding media, such as balls and rock fragments, and are strategically placed within the mill to optimize the grinding action. The grinding sections help in reducing the ore to the desired size by continuously impacting and grinding the material.
