The working principle of ball mill
The ball ratio is usually selected from 2:1 to 5:1. In some cases, a large ball-to-batch ratio is used. For example, a wet-milled titanium carbide-based carbide bar can be used for 6:1. Because the volume of the mixture is large at this time. It seems that using the ball to material volume ratio to indicate the amount of charge will be more ...

The Colors of Billiard (Pool) Balls: Solids & Stripes
They are numbered 1-15. Numbers 1-8 are solid colored balls, meaning the whole ball is one color except for the where it is numbered. And number 9-15 are striped balls. The striped balls have a stripe of color around them with the rest of the ball being white. These two different color patterns make it easy to tell them apart when playing pool.
What is the Difference Between Tumbling Mill and Ball Mill?
A: Yes, a ball mill can be used as a tumbling mill, but the reverse is not true. Tumbling mills are specifically designed for size reduction using a combination of forces, while ball mills are designed for grinding using impact and attrition forces. Explore the fundamental differences between these two grinding equipment and how they can impact ...
