Ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Raymond mill is used for grinding the barite, limestone, kaolin, ceramics, and slags, etc, with the hardness below scale 9.3 of Mohs and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industry, chemical engineering and building material for high fine powder generating and processing. The particle size of finished product can be adjusted from 80 to 325 meshes at random and the particle size of part materials can reach 2000 meshes at the maximum.
Generally speaking, the structure, working principle, use and application scope of ball mill and Raymond mill are different, so the ball mill and raymond mill have each advantages.
However, the particle shape from ball mill is good than raymond mill, so if customer is strict on particle shape, had better choose ball mill. While if not, Raymond mill is also better.
This ball mill has two warehouses and its outside runs along the gear,the material enters spirally and evenly to the first warehouse of the milling machine. In this warehouse, there is a ladder scale board or ripple scale board, and different specification steel balls are installed on the scale board, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried to some height and falls , thus to make the material grinding and striking. After coarse grinding of the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scale board. finally, the powder is discharged by output material board and the process of grinding is completed.
However, When Raymond mill is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.
