Wet magnetic separator is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals.
Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Feb 08, 2017· The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs duringimpact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed through thecentral hole in the discharge cap or through the grid…Chat Online
Ball millingand ultrasonication were used to reduce the particle size and distribution. Duringball millingthe weight (grams) ratio of balls-to-clay particles was 100:2.5 and themilling operationwas run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied.Online Chat

Ball milling is asize reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion.Online Chat

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of theindependent variables are non-linear or have paradoxical effects on the end results.Online Chat
