The ball mill is a key equipment for regrinding. It is widely used for the cement, iron ore beneficiation, gold ore beneficition, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process.
The acid insolubles value is a measure of the amount of material insoluble in mineral acid. In copper, a large part of this material is found to be complex compounds of copper with other elements. Particle shape depends on the production method. Copper powders, produced by the methods discussed, can be spherical, irregular or dendritic.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
