  • The working principle of ball millMeetyou Carbide

     · The ball ratio is usually selected from 2 1 to 5 1. In some cases a large ball-to-batch ratio is used. For example a wet-milled titanium carbide-based carbide bar can be used for 6 1. Because the volume of the mixture is large at this time. It seems that using the ball to material volume ratio to indicate the amount of charge will be more

    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.
