Function of ball mill and sprydyr and all function

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

    A device used to reduce the particle size of materials, bodies or glazes. A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low speed or
