size reduction by ball mill design

Ball Mill Application and Design Paul O. Abbe

Ball mills are used the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, metal oxides, solar cell and semiconductor materials, nutraceuticals and pharmaceuticals materials down to 1 micron or less. The residence time in ball mills is long enough that all particles get consistent treatment, which also provides a narrow particle size distribution. Ball mills are simple in design, consisting of horizontal slow rotating vessels half

09/05/2018· BALL MILL: These are also knows as tumbling mills or pebble mills. Principle: The ball mill works on the principle of impact between the rapidly moving balls and the powder material, both enclosed in a hollow cylinder. At low speed the balls roll over each other attrition will be mode of action thus in the ball mill attrition and impact both mechanisms takes place. 23 24. Construction: It

A specific energy-based size reduction model for batch

01/01/2015· A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 –t n relationships and the mass-size balance approach.
