Overflow VS Grate Discharge Ball or Mill Why Retrofit

Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve.Overflow discharge mills give a final product in an open circuit.

What Mesh Sieve Do You Screen To For Dipping Glazes

Aug 16, 2015· A ball mil will actually reduce the particle size, although for most glazes it's overkill. Not worth the effort most of the time. Many glaze manufacturers us high shear mixers for their glazes, which negates the need for sieving and can also reduce the particle size. If you're not having any problems with the 80 mesh, no need to do anything finer.
