Difference Between Ball Mill and Raymond Mill

Posted by dongfang on September 18th, 2017

Both the ball mill and raymond mill are powder grinding equipments.The fundamental difference between them is that the raymond mill is sand -making equipment while the ball mill is ore beneficiation equipment.Raymond mill is widely used in barite, limestone, fluorite, calcite, potash feldspar, talc, marble, lime, active white soil, phosphate ore, activated carbon, gypsum, glass, bentonite, kaolin and insulation materials that have the Moh’s hardness scale less than 9.3 and the humidity of less than 6%,non-flammable and explosive materials.And the particle size of finished product can be adjusted from 80-325 meshes at random. Besides, some materials can reach 2000 mesh.The ball mill is widely used in refractories, cement, new building materials, glass ceramics, silicate products, black and non-ferrous metal beneficiation and other production industries. Moreover, the equipment can also be divided into dry-type ball mill and wet-type ball mill. The discharging speed of ball mill is fast, and the product granularity is relatively coarse. The outstanding advantages of raymond mill are: stable performance, convenient operation, low energy consumption, wide range of product granularity adjustment. So it is suitable for fine grinding of nonmetal under some medium hardness. The feeding size of raymond mill is generally 15~20mm, mainly used for Moh’s hardness scale under 9.3, and humidity is less than 6% of a variety of ores, building materials, chemical materials which are the non-flammable, not easy to explode, such as superfine crushing processing. The finished product fineness of up to 2000 mesh. So it is suitable for some material with fineness requirements. Ball mill, which is suitable for the materials whose Moh's hardness is below 7, humidity is below 6%, is extensively used in the black and nonferrous materials processing, fertilizer processing, refractory processing, silicide processing etc. The material can be dry-type, wet-type grinding.The finished product fineness can be up to 425 mesh at most.It is commonly used in mineral processing production line of material grinding.
