The difference between Raymond Mill and Ball Mill

Ball Mill and Raymond mill are the key equipment for grinding materials, in general terms the use of the two is the same, it seems no difference, but in actual use, there is a big difference between them. Today we will listen to experts explain Raymond mill and ball mill differences and connections.
 
1, Application difference between ball mill and Raymond mill
 
Ball mill is more widely used in beneficiation field and Raymond mill more widely used in sand and gravel production line.
 
Ball mill is widely used in mineral processing plant, refractory plant, cement, glass, etc., using energy-efficient ball bearings, overflow discharge can save 30% energy than conventional ball mill. This machine is suitable for grinding various ores and other materials are widely used in mineral processing, building materials and chemical industry can be divided into two kinds of dry and wet grinding methods, wet ball mill is the material wet ground water seepage, dry ball mill seepage dry grinding is not allowed. According to the same manner of discharge can be divided into two kinds of lattice type and overflow.
 
Raymond mill is widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock , plaster, glass, insulation materials Mohs hardness of not greater than 9.3, high fine powder processing and humidity below 6% of non-flammable mineral, chemical, construction and other industries more than 280 kinds of materials, R-type Raymond Mill finished size within the range of 80-325 mesh of arbitrary regulation, part of the material up to 600 mesh.
 
2, Working Principle difference between ball mill and Raymond mill   
 
Ball mill is a horizontal cylindrical rotating device, material from the feed device into the compound by the air shaft into the mill screw evenly the first warehouse, there are ladder liner or corrugated liner inside the warehouse, and is equipped with different specifications of steel balls, rotating cylinder produces centrifugal force to the ball a certain height.  After the fall, have severe impact on the material and abrasive. The material in the first position coarse, the single-compartment plate into the second position, the material is further ground in the warehouse, the final powder is discharged through the discharge grate plate to complete the grinding.
      
The material entered Raymond mill is needed from the side of the machine casing feed hopper into the machine, is suspended from the host device about the vertical axis roller revolution motion, while their rotation, the centrifugal force due to rotation, the roller outside swing, pressed on grinding ring, so the shovel blade materials sent between roller and grinding ring rolling mill rolls because the material compacted crushed.
 
3, structure difference between ball mill and Raymond mill
 
Ball mill consists of the feeding part, discharging part, turning part and driving and other components. Hollow shaft with steel fittings, removable lining, rotary gear hobbing by casting process, the body inlaid cylinder liner wear, has good abrasion resistance.
      
Raymond mill mainly consists of the host, analyzers, blower, finished cyclone, cyclone powder and wind pipe. Among them, the master and the roller, grinding ring, rack, inlet volute, blade and housing components.
