Table of ContentsData on Ball ChargesBall Mill Ball Wear ProjectionRecapitulation of Ball Wear FormulasPractical Application of Theoretical Conclusions In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the
Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Wet Ball Mill Power Draw (Bond)

Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials.
The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of discharging material: grate type, and overfall type. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

Charging a Dry Mill The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much.
With more than 100 years of experience in ball mill technology, Metso’s ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.
Ball mill is a common grinding machine. It is also the key equipment in grinding industry. Ball mill is suitable for grinding various materials with different hardness and humidity. That's because it has two kind of grinding modes, dry process and wet process. Customers can control the capacity and final products' fineness by adjusting the
