100 mm) and high moisture (20 %); whereas Ball Mills can normally accommodate (up to 25 mm) moisture up to 12 %. Traditionally vertical roller mills operate with feed around 80— 100 mm size but reducing this to lower size has proven beneficial to capacity enhancement in number of plants; with ball mills the finer the raw materials feed size ...
The Mohs scale of mineral hardness is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable
