· Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.

Plus de détailsWhen the ball is rotated against the Tang cylinder, the minimum speed is called the critical speed, and the critical speed n can be alculated by: Wherein D is the diameter of the mill barrel (meter). Let D = 0.5 m, then. This is the critical speed of the 180 litre wet mill currently used in cemented carbide production.

Plus de détailsThe 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.
