The selection of the material of construction is a function of the application abrasivity of ore size of mill corrosion environment size of balls mill speed etc liner design and material of construction are integral and cannot be chosen in isolation A list of the primary material of construction is given with

Mill Selection The first step in mill design is to determine the power needed to produce the desired grind in the chosen ore The most used equation for this purpose is the empirical Bond equation Bond 1960 1961 Rowland and Kjos 1978

Energy consumption for ball mills is a function of many factors the physical properties of the ground material – its specific gravity and hardness the degree of drum filling by grinding balls the number of drum rotations etc Ball mills have low efficiency – no more than 15

mill absorbed power and ball filling degree As indicated on the graph a small variation in power could be the result of a significant variation of balls filling degree As the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate The risk of underloading or

The type of mill also can affect the selection of grinding media Ball Mills use very large media while Attritors employ media ranging in size from 18” to 1” Horizontal mills require much smaller media as small as 005 mm to 2 mm To read detailed specs and submit a quote click here for our metallic media or here for our nonmetallic media
