Ball mills have been the primary piece of machinery in traditional hard rock circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling can be justified by an operation.
Ball mill is the key equipment for deep grinding of materials after primary crushing. It is widely used in cement, silicate products, new building materials, wearresistant materials, fertilizers, ferrous and nonferrous metal mineral processing and glass ceramics industries.
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. These mills are sized from 2 t/h to 30 TPH for wet grinding and from t/h to 30 TPH for dry grinding.

Extensively field tested and proven in harsh cement applications, our mill drive gearboxes cover all grinding applications up to 10 MW per drive and we have single, double and triple reduction gearing ...
However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 – 30%, is not enough to offset Its higher cost. In primary ball milling, wear speed is largely independent of ball diameter and mill volume.
Mar 20, 2017· Ball Mills: The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills." Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing.
Autogenous and semiautogenous mills are designed for grinding or primary crushed ore and are the most widely used in concentrators globally. Ball mills Ball mills are typically used for secondary and/or tertiary grinding to prepare the material for downstream concentration processes. Rod mills Rod mills are mainly used for primary grinding of
In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 pm. This duty represents reduction ratios as great as 100. The ball mill, an intermediate and finegrinding device, is a tumbling drum with a 40% to 50% filling of balls (usually steel or steel alloys).
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
