Raymond Mill workflow and principle

Structure:

Raymond mill entire structure by the host, analysis machine, plumbing fixtures, blower, finished cyclone, jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric motors and other components Where Raymond host from the rack, into the wind volute, blade, roller, grinding ring, casing and motor

Raymond entire work process (grinding material process): a large block of material by jaw crusher to the desired size after the material sent by the hoisting machine hopper, and then send continuously through uniform quantitative feeder interior grinding into the grinding, grinding the powder was taken away after the fan airflow The analysis machine grading, in line with the fineness of the powder with the air through pipes into a large cyclone collector, were separated and collected, and then the powder discharge pipe is finished powder Stream again by a large cyclone collector upper return duct suction blower The whole machine is closed loop gas flow system, and is in a state of negative pressure circulating
Working principle:
Raymond hosts work process is driven by rotation of the central axis of the transmission, the upper end of the shaft is connected to plum frame, rack mounted roller is installed to form a swing fulcrum, rotating around the center of not only the country, but around the roller grinding ring revolution Meanwhile, the roller itself due to the friction and rotation Plum frame with the bottom of the blade system, its position in the lower end of the roller, roller blade and process with the transfer of the material between the feed roller shovel throw ring, forming litter layer, the material layer by the rotation of the roller outward centrifugal force (ie, pressing force) the material is crushed, the resulting flour milling purposes
Analysis via by two slow speed motor and drive 60 blades on the turntable rotates, the powder form of hierarchical role Speed blade speed is based on the size of the finished powder Liaoduo adjusted When To obtain more finegrained powder neutrons must increase blade speed, the blades in contact with the powder will increase, so that the powder is undesirable thrown to the outer wall of the air flow from the blade, coarse child due to the action of gravity falls from grinding chamber regrinding, qualified finished powder was with the air leaves a large cyclone collector inhalation, the airflow and the powder will be separated, the powder was collected And so on
