In recent years, with the development of science and technology, China's ultra-fine powder technology has not been the same, and non-mineral resources are increasingly entering all walks of life, three-ring medium-speed micro-grinding, ultrafine mill machine and other super The emergence of fine powder processing equipment has brought a major change to the mining machinery industry and promoted the development of ultra-fine powder processing technology in China. For the customers, they are confused about the three-ring medium-speed micro-grinding and ultra-fine grinding machine. The main thing is to listen to the manufacturer's explanations to understand the processing materials, technology and other information of the equipment. So is the processing of ore material in the end three-ring medium-speed micro-grinding or ultra-fine grinding machine more suitable? According to the development of SBM's mining machinery manufacturing for decades, as a high-performance equipment manufacturer, each product has been widely used in many industries, such as metallurgy, building materials, chemicals, mining, pigments and other industries. In fact, whether it is a three-ring medium-speed micro-grinding or ultra-fine grinding machine, its development determines the rational development and comprehensive utilization of non-metallic minerals to a certain extent. Faced with the fierce competition in the mining machinery industry, SBM has organized a professional technical team to deduce the grinding equipment processing technology and its improvement in the requirements of the general ultra-fine powder, especially in the country to encourage and support the independent development of China's mining industry. Not only the raw materials, production process and technology content of the milling equipment have been greatly improved. Moreover, SBM independently developed a new type of three-ring medium-speed micro-grinding and ultra-fine grinding equipment. In the future research and development of grinding equipment, SBM will adopt a new second-order staggered three-ring medium-speed micro-grinding. The relative number of the fifth-stage grinding rolls in the upper layer is small, which is beneficial to the large-grain material entering the grinding ring passage, and the quality of the grinding roller is relatively large. The centrifugal force generated by the grinding roller is large, the main working principle is impact crushing, suitable for coarse breaking; the lower order has an average distribution of 10 grinding rolls, and the relative number of grinding rolls is relatively large, which can appropriately increase the grinding probability of small particles and increase the yield. The volume and quality of the grinding roller are relatively small, mainly used for rolling and grinding, which is suitable for fine breaking. Look forward to our new products coming out fresh.
