Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

The larger pieces of ore keep the rods apart so that the grinding action is concentrated on the larger sizes and the smaller particles are not overground to the same extent as in a ball mill. For these reasons the shell is made about 50% longer than that of a ball mill of the same diameter and still gives less undersize when grinding the same tonnage to the same mesh.

Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today’s global markets, expanding mining groups are trying

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.

There are kinds of ball mills according to their different functions such as dry type mill, wet type mill, grid ball mill and overflow ball mill. As we have known the varieties of ball mill, let's come back to the point and talk about the ways to increase ball mill efficiency. Generally speaking, there are three simple and direct means to ...

It can produce ultrafine powder, low energy consumption low investment cost, large scale ring roller mill has good market prospect. Disadvantage: low output. 4.Ball mill +classifying: High energy consumption, it is almost obsolete in nonmetallic mineral industry. The process flow of limestone powder production.

What is the efficiency of a milling process? Different possibilities to define energy efficiency: 1. Specific energy of mill compared to new created surface energy → not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However, here at least two
