indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball 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.

Apr 19, 2013· Since delivery time for parts to repair the damaged drive was lengthy, a decision was made to reduce the charge in the ball mill from approximate 32% filling level to a point low enough to allow the mill to be operated with the single remaining drive. Surprisingly the result was a minimal loss in production, with a significant gain in efficiency.

Sagmilling is home to a collection of both free and subscription-based calculation tools to aid metallurgical process engineers perform comminution calculations. Grinding circuit design tools, including for SAG mill-ball mill circuits, and geometallurgy energy models are available to subscribers.

It seems to be a Hardinge Electric Ear revisited. This device was patented by Hardinge in the thirties to be used in a ball mill with fixed speed and an almost constant volumetric filling level, given the appropriate ball make up. The load remains approximately at the same place all the time, such that with only one sensor you cope all conditions.

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
