Product Description

Ball mill steel forging is a basic part used for grinding materials in ball mill equipment, which produces abrasion and stripping effect through the collision and friction between steel forging and materials. They play an important role in the national economy, especially in cement plants, power plants and other widely used. Ball mill steel forging is made of various materials, including high and low chromium multi-element alloy steel ball, high and low chromium multi-element alloy casting and forging, etc. These materials can adapt to the requirements of different working environments and accomplish specific grinding tasks.
