    What is ball milling? A ball mill is a type of grinder used to grind materials into extremely fine powder 7 Major parameters for ball milling Temperature Size and Number of the balls Nature of the balls Rotation speed 8 Types of Ball Mills1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature andBall Mill Parameter Selection & Calculation Poweragitator shaft speed and milling time that cost less energy while at the same time do not compromise the quality of the fat filling Optimization of production of fat filling in a laboratory ball mill would imply the maximum agitator shaft speed and 30min milling time Keywords: fat filling, ball mill milling variables, physical properties,OPTIMIZATION OF THE BALL MILL PROCESSING
