Dec 15, 2000 For grinding cast iron, non-ferrous metals and non-metallic materials, select a silicon carbide abrasive. Hard, brittle materials generally require a wheel with a fine grit size and a softer grade. Hard materials resist the penetration of abrasive grains and cause them to dull quickly.
3. The humidity of the grinding materials. If the raw materials contain high percent water, the materials will easily adhere to the surface of the grinding mill and block the grinding speed. 4. The composition of the grinding materials. If there is much powder in the raw material, it may reduce down the capacity since the powder will easily adhere.

Classification is the Key to Fine Gold Recovery. It is well-established that if you want to effectively recover finer particles of gold, you must first separate them from the larger-sized materials which are being washed through your recovery system by a higher-velocity flow of water. The small-sized material can then be directed to a milder-flow of water over a shorter set of riffles.
