Raw Ball Mill Grinder Introduction:
As an industrial raw material, powder is widely used in cement industry, building materials industry, metallurgy industry, chemical industry, electric power industry, paint industry, rubber industry, plastic industry, cosmetics industry, etc. The particle size of conventional industrial powder is 1 ~ 10μm, and 0.1 ~ 1μm for fine powder, 1 ~ 100nm for ultrafine powder or nano powder. The particle size by ball mill or vertical mill equipment both can reach 1 ~ 10μm, each of which has advantages and disadvantages.
Applied Materials:
Copper, magnetite, molybdenite, zinc ore, iron ore, gold, hematite, fluorspar, lead & zinc, manganese, tungsten, marble, granite, slag, cement, limestone, clinker, coal etc
The most widely used in the classification of mills, and the most classic is the ball mill. Ball grinding mill (ball grinding mill) is the key equipment for crushing materials and then crushing. It is mainly used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics production industries. The ball mill can be divided into two types: lattice type and overflow type according to different ore discharging methods. It can be divided into dry and wet grinding methods. It is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industry. And other industries.
Working Principle:
Vertical Raw Mill
Vertical raw mill uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials. Feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers. Coarser material and bigger lumps drops through the nozzle ring – and is eventually recirculated into the feed material inlet. Moisture evaporates almost immediately as the gas stream carries the finer portion of material to the separator. The separator allows material that has reached the required fineness to leave the grinding mill and sends oversized material back for further grinding.
Horizontal Raw Mill
The raw mill is a horizontal rotating device transmitted by the gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of grinding media in the chamber. The centrifugal force caused by rotation of shell brings the grinding media to a certain height and impact and grind the materials. The fine materials are discharged through the outlet, thus the grinding process is finished.
