Forged Grinding Balls

Forged grinding balls commonly used low-carbon alloy, high manganese steel, high carbon and high
manganese alloy steel. On the basis of these material we have developed a series of competitive and efficient patent forged grinding balls.

Forged grinding balls
The products range from 20mm to 150mm, 1 inch to 6 inch, and we can also offer all size of products according to customers’  demands.
