How to select a ball mill?
Generally speaking, enterprises in the selection of mining equipment, need to consider comprehensively, understand the nature of minerals, abrasive requirements, production environment and energy consumption conditions and so on. After scientific analysis to choose suitable ball mill equipment.
1. Understand the properties of minerals
(1) In the face of different dry and wet conditions during grinding, ball mills can be divided into dry ball mills and wet ball mills.
In general, a variety of metal and non-metallic ores containing water will use dry ball mills, as well as cement, marble and other building stones, or products need to be stored or sold in the form of powder, dry ball mills will also be used. In addition, the selected plant area is located in the water shortage area, in order to save rare water resources, dry ball mill will be used.
Wet ball mill has a wider range of applications. In a variety of metal and non-metal mines are very common applications, as long as the need to deal with the material will not react with water, resulting in the quality of the product has an impact, can use wet ball mill for processing, generally speaking, the separation equipment used in the concentrator is wet ball mill.
Wet ball mill
(2) In the face of different grinding media, ball mills can be divided into ball mills, automills or rod mills.
As the name suggests, the self-grinding machine does not need to add additional grinding medium, only rely on the mineral itself as the medium, suitable for rough materials with its own grinding to achieve self-grinding. There is a wide range of materials that can be used in an automill, of any nature. Especially when dealing with iron ore, gold ore, manganese ore, asbestos tile, copper and limestone such materials, autogenous grinding machine to obtain better grinding effect.
Ball mill is added grinding medium steel ball in the mill to participate in grinding, more suitable for fine material grinding mud, adaptability is also stronger, common materials such as aluminum ash, lime, slag, molybdenum ore.
Rod mills are more commonly used in grinding brittle minerals to avoid over-grinding, and are more commonly used in gravity and magnetic separation of rare metals such as tungsten and tin.
