What are the steps of Raymond mill powder

Raymond mill is most widely used and can be used for barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, such as cement, phosphate rock, gypsum, glass mohs hardness is not greater than 9.3, and the humidity below 10% of non flammable and explosive mineral, chemical industry, construction and other industries more than 280 kinds of materials is high, the fine powder processing, finished product size adjusted within the range 80-325 mesh, part of the material up to 600 mesh. Raymond mill principle of work, after the material into the Raymond mill host grinding chamber, the spindle under the effect of rotating centrifugal force, roller swing outward, press in grinding ring, shovel knife scooping up material sent to the between grinding roller and grinding ring, along with the roller rolling grinding, milling and to achieve. After grinding material, powder with blower wind circulation through the analysis of machine for sorting, fine fall back into the grinding chamber through the coarse material resharpening, qualified fine powder increases with airflow into the cyclone powder, the powder tube drainage.

The air flow passes through the cyclone collector and then enters the blower to form a closed-loop cycle, so that the machine can work continuously, while the residual wind is going through the exhaust pipe to the dust collector to purify the back of the machine. Raymond mill pre-grinding process: grinding mill as the front grinding mill of Raymond mill, the material is premilling; The grinding mill is a grinding mill, in which the finishing mill is finished and the grinding work is finished. Using this process can increase the yield of grinding mill by 20% to 50%. 4-8kw/h per ton of cement. The semi - final grinding process of the ramon mill: it is a circulating system that combines the extrusion grinding into the ramon mill. After extruding the crushed material (cake) is sent to the disperser to break, become a loose granule of untangled mass, then feed into the separator and select the powder. The selected coarse powder is sent back to the extrusion mill, and the other part is fed to the grinding machine for final powder grinding: the powder produced by the pulverizer, and the material discharged by Raymond mill. Together as a powder mill product. Because of the extrusion mill in this process, a part of grinding products is directly provided, so it is called semi-finishing grinding process. Remoning mill finish grinding process: it is used separately to use extrusion mill without Raymond mill. Material discharged from squeezing grinding cake, send people scattered machine SongSanHua, be not loose particles, and then into the classifier classification, classifier is fine powder grinding products, coarse powder is returned to squeeze grinding cycle again. When grinding cement, rather than used to mill, every tons of cement can power saving half in this process, the process of cement, because the grain size composition and mill grinding of cement, and cement particle roundness is poorer, so the properties of cement is test faults, performance on the setting time short and water needed is bigger. Ramon grinding mill process: it is a circulatory system that combines extrusion grinding into Raymond mill. First, feed the material to the mill, then crush the crush of the cake flour mill to continue grinding mill. A part of the pulverizer is sent back to the extrusion grinding cycle. Another part is grinding mill powder. The powder of the separator is the product. When grinding cement, using this process can increase the production of the grinder by 30% or even 100%, which can save 15% to 50%.
