What are the uses of Ball Mill – Promas Engineering Pvt. Ltd.

The balls can be in a different diameter that occupies 30-50% of the mill volume and the size depends on the mill size and feed. The big balls eventually tend to break the coarse materials and small balls help to form a perfect product that reduces unnecessary spaces between balls. Ball mills grind the material by attrition and impact.
