The use of non-metallic minerals is mainly manifested in the degree of deep processing, including ultra-fine pulverization, fine grading, refining and modification. Therefore, the development of ultrafine mill technology and ultra-fine grinding machine equipment determines the rational development and comprehensive utilization of non-metallic minerals to a certain extent. At present, all kinds of ultra-fine grinding equipment and fine crushing equipment have been produced in China. The performance and technology of the equipment have gradually approached the world advanced level. Some of the equipments such as SBM Heavy Industry's ultra-fine grinding machine have reached the fineness of grinding. A very high level of technology.
As the main equipment of the pre-crushing process, the ultra-fine mill has been successfully applied to the raw material grinding system, which has the effect of increasing production and energy saving. However, the effect of a considerable number of cement plants is not satisfactory, mainly due to the serious wear of the plate hammer and the lining plate, failing to meet the design requirements, and the effect of increasing the output of the mill is not obvious. At present, the idea and direction of the pre-crushing process of the cement grinding system using the vertical impact crusher is correct. The main reason for the unsuccessful success of many cement plants is the unreasonable design of the pre-crushing process of the mill and the improper selection of the process parameters of the cement grinding system. of.
Especially with the rapid development of industrial production and manufacturing technology, high-fine micro-powder has become more and more important for industrial production, and ultra-fine grinding machine is the future development direction. When we used the traditional mill grinding machine, we found that the Raymond mill can not guarantee the yield and fineness of the material when the processing fineness exceeds 325 mesh, which meets the demand of ultra-fine powder in modern industry. The appearance of ultra-fine grinding machine is undoubtedly born. SBM heavy-duty ultra-fine grinding machine is divided into high-pressure micro-powder grinding machine, three-ring medium-speed grinding machine, ultra-pressure V-type grinding machine and other ultra-fine grinding equipment. High output and low energy consumption, using pulse dust collector to capture dust, using muffler to reduce noise, environmentally friendly and clean. There is no rolling bearing or screw in the grinding cavity, so there is no problem that the bearing and its sealing parts are vulnerable. There is no problem that the screw is easy to loose and destroy the machine; the grinding roller and the grinding ring are forged by special materials, so that the degree of utilization is utilized. Greatly improve.
