Raymond also called Raymond mill, the full name of , grinding process is widely used within the metallurgy, building materials, chemicals, mining minerals in areas such as materials, product fineness can reach 0.044mm. Raymond (Raymond) common sense: Hardness: Because it is destructive test, so the rough or unpolished precious of minerals can not be used. Hardness scale has two categories, one is the absolute hardness, and the other is a Mohs hardness (a relatively hardness) Mohs hardness: the ten common minerals come as standard with a scratch each other hard to distinguish what what soft , it is customary on mineralogy or gemology are using Mohs hardness. Head is a general characterization of sieve aperture size, its conversion formula is cm = 16 / mesh, mesh has British and American, British refers to the number of holes per square inch; Raymond (Raymond) Scope: Raymond (Raymond) mainly suitable for metallurgy, building materials, chemicals, mining and other mineral materials milling equipment. Grinding range is: quartz, feldspar, kaolin, bentonite, calcite, talcum, barite, fluorite, clay, marble, limestone, dolomite, lime, activated carbon, kaolin, phosphate rock, glass, manganese ore, refractory materials, insulation materials, lime mud, paraffin stone, mullite, stone, attapulgite, magnesium ore, iron ore, copper ore, silicon ore, magnesium oxide, barium salt, etc. Mohs hardness of 7- 8, humidity below 6% of various non-combustible and explosive material grinding mineral processing. Raymond (Raymond) Main structure: Raymond (Raymond) structure mainly by the host, analysis machine, blower, finished cyclone, powder cyclone and duct components. Among them, the host from the rack, inlet volute, blade, roller, grinding ring, casing and motor. Raymond (Raymond) Workflow: Bulk purified by jaw crusher broken to the desired size (such as material reaches Raymond (Raymond) Feed 2 cm size requirements may not need Crusher ), crushing the material evenly require continuous feeding Raymond (Raymond) host grinding chamber, since the centrifugal force, the roller swings outward rotation, pressed on the grinding ring, the shovel blade materials to the mill between roller and grinding ring, due to the rolling mill rolls to achieve the purpose of crushing, grinding the powder was taken away after the fan airflow, the analysis machine extension, in line with the powder fineness with the airflow through the pipe into a large cyclone collector inside, they were separated and collected, after the discharge is finished powder charge. Stream again by a large cyclone collector upper return duct suction blower. Native entire stream system is a closed loop, and is under negative pressure state circulating. If no hoists, storage silos, vibrating feeder, can be manually uniform feeding. Is generated when the ground because there is a certain moisture content of the material, grinding mill indoor heat leads to an increase in milling chamber air flow, for pipe came to equilibrium by adjusting the airflow over the wind turbine and the host, and the excess into the atmosphere after purification , the bag should always shake so good exhaust effect. Raymond Accessories: Raymond accessories roller, grinding ring roller assembly, plum frame, reducer, fans, air duct plate, bearing, blade, blade holder, oil seals, roller shaft, under gland, etc., SBM Raymond mechanical long-term preferential supply various accessories, welcome to buy! Raymond (Raymond) How it works: Raymond mill (Raymond) works under the centrifugal force roller tightly rolled in the mill Sheung Wan, the shovel blade materials to roll grinding and grinding ring middle, crushed into powder material under grinding pressure of the role, and then under the action of the fan to blow up into a powder material through analysis machine, reaching fineness material requirements by analyzing the machine, who fail to return to the grinding chamber to continue grinding machines by analyzing the material into a cyclone separator to collect processor. When heat is generated by the grinding mill indoors due to a certain moisture content of the material, grinding mill indoor gas evaporated lead to change air flow, and the machine does not close all pipe connections so that the outside air is sucked, so that air circulation flow increased, leading to mill machine flour even less blasting machine, which, the new European version of the mill has been provided with a ladder-proof measures in the upper body, you can maximize avoid Raymond machine explosion caused injuries, while such the case can also be adjusted over the fan duct and the host to achieve a balance between airflow and excess gas is introduced into the small cyclone collector, the residual gas into a fine powder-collecting down by the last paragraph on the small cyclone collector the exhaust pipe into the atmosphere, or introduced into the dust collector makes emptying gas purification, however, the operator’s technical requirements are relatively high, and the need to detect and adjust.
