Jul 20 2020 The ball mill grinds the feed to a fine powder in two chambers namely the first and second chambers The two chambers have a certain quantity of ball charge of different sizes from 17mm to 90 mm The mill discharge is fed to a bucket elevator which takes the material to a separator which separates fine and coarse product

Ball mills normally operate with an approximate ball charge of 30 Ball mills are characterized by their smaller comparatively diameter and longer length and often have a length 15 to 25 times the diameter The feed is at one end of the cylinder and the discharge is at the other

Cement Tube mill internals Grinding media Changing impact conditions can cause conventional grinding media to either work harden or cause spalling thus shortening working life increasing downtime and increasing costs The Group Industries has developed a whole series of alloys specifically suited to the different impact and

May 22 2019 The larger the ball to material ratio the higher the grinding efficiency But too high a ball ratio is unhelpful Because the amount of charge is reduced when the filling factor is constant it is bound to reduce the productivity of the set and sometimes reduce the alloy properties Figure 82 The ball ratio is usually selected from 21 to 51

On top of that the ball charge distribution should be similar to that used in the industrial mill to get useful results Typically at least three single ball sizes are needed to unambig
