The application and working principle of Raymond Mill

The application and working principle of Raymond Mill
httpwwwfinenesscrushernetproductsgrinding-machineraymond-millhtml

Raymond mill is widely used in barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials Mohs hardness is less than 7, high fine powder processing at 6% humidity the following non inflammable and explosive mineral, chemical, construction and other industries more than 300 kinds of materials, R type Raymond mill finished product size 80 to 325 mesh range of arbitrary regulation, the highest part of the material can reach 600 mesh.

Raymond mill structure is mainly composed of a host machine, a blower, analysis, product cyclone separator, piping device, motor and other components. The host is composed of a machine frame, a wind inlet volute, blade, roll grinding, grinding ring, a cover casing and a motor. Auxiliary equipment are jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control cabinet, the user can choose flexibly according to the scene.

Raymond mill machine will work when the bulk raw material crushing to the feed particle size required, by the bucket elevator to transport material to a storage bin, and then by the electromagnetic vibration feeder evenly sent to the host of the grinding chamber, into the mill interior material is shovel knife entered between rollers and ring are ground the air from the blower, a diffluence disk blown into the grinding chamber, the crushed powder to the analysis room, after separation from the motor through the transmission device to drive the analysis of impeller rotation, the large particles fall back to the fine grinding powder chamber, re grinding, qualified with the airflow into the finished product cyclone powder collector, and after air separation, discharge from the discharge opening for the product. The host in the work process, blade system plays a very important role. 

It is located in the lower end of the grinding roller and grinding roller with blade, in the rotation process the material shoveling throwing feed between the grinding roller ring, forming a pad layer, the layer produced by grinding rotary roll outward extrusion pressure would crush the materials, so as to achieve the purpose of milling.

The use of advanced structure of similar products abroad, Raymond mill, and based on a large of Raymond Mill on improving design and updated. The ball mill equipment than the high efficiency, low power consumption, small occupation area, less investment. Function of grinding roller under the centrifugal force in the grinding ring tightly compacted, so when the grinding ring wear to a certain thickness does not affect the yield and fineness of grinding roller, finished product. Roll grinding, grinding ring replacement cycle is long, thus rejecting the centrifugal pulverizer wearing parts replacement cycle short ills.

Winnowing airflow Raymond mill is in fan - mill shell - cyclone fan internal circulation flow operation, so the ratio of high-speed centrifugal pulverizer.
