Manganese ore has high industrial value. Manganese ore can be ground into fine powder by dry mill equipment. The fine manganese ore powder processed by manganese ore grinding mill is the main raw material for making metal manganese and alloy additives. It is also one of the important auxiliary materials for the production of cement retarders, and can also be used to make refractory materials and ceramic glazes.

At present, manganese dioxide ore grinding mill process mainly includes dry grinding and wet ball milling. Among them, wet grinding consumes a lot of energy, and the equipment is bulky and noisy. It is difficult to accurately control the product size, and it is difficult to accurately measure the material. It is difficult to maintain the stability of the subsequent continuous leaching process. The dry grinding process is relatively mature, the process is relatively short, the configuration is relatively simple, and it is easy to control the subsequent continuous leaching process; With the development of modern dry grinding mill equipment and technology, the dust problem has been significantly improved. At present, the manganese industry generally adopts dry grinding technology.

The key of dry grinding process is the selection of manganese ore grinding mill equipment, including manganese ore vertical mill, manganese ore Raymond mill, manganese ore dry ball mill, manganese ore high pressure roller mill and other equipment. The following mainly introduces two types of manganese ore dry grinding equipment, namely, manganese ore Raymond mill and manganese ore vertical mill.

HC series manganese ore Raymond mill is a large, efficient and environmentally friendly manganese ore grinding mill independently developed by HCMilling(Guilin Hongcheng) Mining Equipment Manufacturing Co., Ltd. The main machine adopts the integral casting base structure, and can adopt the damping foundation. At the same time, the offline dust cleaning pulse system or afterwind pulse dust collection system is adopted, which has strong dust cleaning effect, long service life of filter bag, and dust collection efficiency up to 99.9%, ensuring environmental protection effect. It can be used as dry grinding equipment for manganese ore, and the fineness of the finished product can reach 38-180 μ m.

The technological process of manganese ore grinding mill is as follows: manganese ore raw materials are fed into the center of the rotating grinding disc by the air-locking feeding equipment, and the materials enter the grinding roller table under the action of centrifugal force. The grinding roller is continuously rotating and rolling, so the material is crushed by extrusion, grinding and shearing. At the same time, the hot air is sprayed from the air ring around the grinding plate at high speed and evenly upwards. The material after grinding is blown up and enters the classifier with the wind. The qualified fine powder passes smoothly and is collected by the dust collection equipment as manganese ore powder.

HLM manganese ore vertical mill produced by HCMilling(Guilin Hongcheng) can be used as manganese ore dry grinding mill equipment. It has the advantages of high grinding efficiency, low power consumption, large feed size, easy adjustment of product fineness, simple equipment process flow, small floor area, low noise, small dust, simple use and maintenance, low operating costs, and low consumption of wear-resistant materials.
