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.
The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power ...
Mills are used in the processing industries for the size reduction of solid materials into smaller, more desirable particle sizes. Size reduction can occur through impact, attrition or crushing. Mills are often used on production lines in the chemical, pharmaceutical, mining, food .
We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
Pinion bearing damage in ball mill. Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the open-pit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill .
The second approach to ball diameter calibration is the so-called absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or thread-driven measuring machine is an example of the absolute concept.
