Manganese metal is divided into metal manganese produced by fire reduction and electrolytic metal manganese produced by wet electrowinning. The pyrometallurgical manganese is massive and difficult to crush; The wet electrolytic manganese metal is flake, easy to crush and high purity. At the same time, the production scale of manganese metal powder is generally large, but the added value of manganese metal powder is not high. These factors determine that the mechanical crushing method is suitable for the production of manganese metal powder, and the raw material used is electrolytic manganese metal. HCMilling(Guilin Hongcheng), as a manufacturer of manganese grinding mill equipment for manganese sheet production, will introduce the factors that affect the selection of manganese powder equipment for manganese sheet production.

The production methods of manganese metal powder can be roughly divided into mechanical pulverization method and physical chemical pulverization method, among which the industrial application methods of mechanical pulverization method mainly include ball milling method, ultra-fine pulverization method, roller crushing method, vertical roller mill pulverization method, etc. The basic principle of mechanical crushing method is to use the brittleness of manganese flakes to crush manganese flakes into manganese powder through shearing, impact, bending, extrusion, grinding, etc.

1. Ball milling method: The ball mill is the oldest grinder, which is still widely used in the preparation of chemical raw materials, ceramic raw materials, coatings and other ultra-fine powders. Ball mill is characterized by large crushing ratio, simple structure, strong mechanical reliability, easy inspection and replacement of worn parts, mature process and standardization, which can be used for both dry and wet crushing. However, the grinding efficiency of the ball mill is low, the energy consumption per unit output is high, the continuous operation cannot be carried out, the grinding medium is easy to wear, and the running noise is high.

2. Ultrafine grinding method: ultra-fine grinding is one of the most commonly used manganese ultra-fine vertical mill equipment, and the product fineness can generally reach 5μm. The product granularity is inversely proportional to the unit energy consumption. The product is characterized by narrow particle size distribution, smooth particle surface, regular particle shape, high purity, high activity, good dispersion, etc. In addition, the process is carried out in a closed system, featuring high automation, simple operation, inert gas protection, few fire and explosion accidents, and few dust generation, so the environmental protection is good. Its disadvantage is that the feeding particles are required to be fine, and the cost is relatively high.

3. Manganese vertical roller mill crushing method: manganese vertical roller mill is a relatively new crushing equipment, which has the advantages of high efficiency, low energy consumption, light wear, low noise, simple operation, wide application range, etc. Compared with the ball mill, the unit energy consumption is reduced by 40%~50%, which can adapt to the operation under different conditions, such as crushing and drying, crushing and mixing at the same time. The metal manganese is hard and brittle, which is more suitable for crushing with a manganese vertical roller mill. The production of manganese powder with Hongcheng HLM vertical mill is not only efficient, but also convenient for system sealing, dust-proof and explosion-proof.

HCMilling(Guilin Hongcheng), as a manufacturer of manganese powder production equipment for manganese flakes, our HLM series manganese vertical roller mill, HC series large manganese flake Raymond mill, HLMX manganese ultra-fine vertical mill and other manganese grinding mills are ideal manganese flake production equipment. They can process 80-2500 meshes of metal manganese powder, with rich customer cases. If you have relevant purchase requirements, please contact us for details of the equipment.
