What's the Difference Between SAG Mill and Ball Mill
The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.
How to Control the Ball Mill Noise? JXSC Machine
The ball mill lays a heat-resistant soft stone mat between the inner surface of the ball mill drum and the liner. To prevent the soft stone mat from overheating, a 10-15 mm thick industrial felt is placed between the ball mill liner and the soft stone mat. The ball mill can Reduce the ball mill noise below the allowable standard.
Ball Mills an overview ScienceDirect Topics
where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
