Ball mill Wikipedia. The ball mill is used for grinding materials such as coal pigments and feldspar for pottery similarly it is suitable for open as well as closed circuit grinding and is applicable for materials of all degrees of hardness Varieties Aside from mon ball mills there is a second type of ball mill called a planetary ball mill Planetary
Ball Mill. 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. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.

This high intensity grinding technology (>300kW/m 3) requires a much smaller footprint than conventional grinding technology the grinding volume of the IsaMill™ is about one tenth the equivalent ball or tower mill.
Amaruq Open Pit Mine is located 127 km N from Baker Lake, Nunavut, Canada. Data Access The grinding circuit is comprised of a primary SAG mill operated in open circuit and a secondary ball mill operated in closed circuit with cyclones. A portion of the cyclone underflow stream is sent to the concentrator, which separates the heavy minerals
The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century. Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling.
