The process of Raymond mill processing kaolin

Kaolin powder dry crushing process is the ore crushing to 5mm or so, after the allocation of separator and collector of Raymond Mill further ground into a powder, it can be most of the sand out. This technology is suitable for processing the high whiteness, particle size distribution of gravel content is low, is suitable for the ore. Raymond mill processing of kaolin used what brand is better? In general, kaolin ore mill mainly used in rubber, plastic, paper and other industries low filler. Its fineness requirements generally at around 200. So according to the range of fineness, can use Shanghai sebang latest upgrade Raymond mill, the European version of MTW series mill. According to different materials, material and production requirements, the machine in addition to the grain size can be adjusted in the 80-3000 mesh size, specifications, production also has the very big difference, can meet the different requirements of customers.

Calcium Spraying of boilers in thermal power plants and using limestone - gypsum method for post combustion flue gas desulphurization purification, is currently the world's most mature technology, with the use of sulfur dioxide emission control technologies most widely. The desulfurization with limestone gypsum powder or grain size in 250 -325 mesh. Power plant 250 limestone powder and limestone powder 325 mesh, the main production include: limestone, limestone, limestone milling storage transport, storage and distribution of limestone powder. 250 mesh and 325 mesh powder limestone desulfurization limestone powder production equipment mainly includes crusher and mill equipment, the choice according to the particle size and particle size of limestone ore, at about 1200mm, the need for the use of crusher crusher, crushing to 30-40mm, can enter the mill for milling. Generally the final grinding particle size will have influence on the desulfurization effect, this is the need of power plant desulfurization of limestone powder in 250 -325 mesh. The preparation of the 250 and 325 mesh of limestone powder, there are two kinds of equipment, one is the European version of MTW milling machine, the other one is LM vertical milling machine, the vertical milling machine production than the MTW European version of mill output will be larger, according to the actual needs can be chosen. MTW European version of LM mill and vertical mill, ball mill in ultrafine powder preparation than energy saving is more significant, and the drying effect is good, has the advantages of small occupation area, advantages, construction investment, etc. at present, most power plant desulfurization of limestone powder preparation are beginning to use domestic mill, such as the Wenzhou power plant, Changxin power plant Xuzhou Xu Tang power, Datang Power Plant Desulfurization System in a power plant in Xiangtan, and were treated with domestic mill, the trend of limestone milling was prepared to replace the potential.
