Raymond Mill and Ball Mill Difference2018-08-22

As we all know that both the Raymond mill and ball mill are the common use stone powder grinding mills. However, there are lots of difference between the Raymond mills and ball mills. In this article we will know the difference between Raymond mill and ball mill from three points, application, structure and working principle.

Application Difference

Raymond mill is widely used in marble, limestone, dolomite, fluorite, potassium feldspar, limestone, calcite, talc, activated clay, activated carbon, cement, phosphate rock, gypsum, glass, thermal insulation materials such as moh’s hardness is not greater than 9.3, and the humidity below 6% of non flammable and explosive mines, chemical industry, construction and other industries more than 280 kinds of materials of high fine milling processing.

Ball mill is the main equipment for crushing after material crushing. Widely used in cement, new building materials, refractory materials, silicate products, chemical fertilizer, black and non-ferrous metal ore dressing and glass ceramics production industry, of all kinds of ores and other materials may be grinding of dry or wet grinding.

Structure Difference

Raymond millis mainly composed of main engine, analyzer, fan, product cyclone separator, micro-powder cyclone separator and air duct. The main engine consists of grinding roller, grinding ring, frame, air inlet volute, spatula and cover.

The ball mill consists of the feeding part, the feeding part, the rotary part and the transmission part. The hollow shaft is made of cast steel, which can be changed and changed. The rotary gear is made of rolling gear, which has a wear-resisting lining board, which has good wear resistance.

Work Principle Difference

Raymond mill is the need to crush materials from hood shell side into the hopper add machine, hanging roller device on a host computer around the vertical axis orbit, itself rotates at the same time, due to the effect of rotating centrifugal force when the roller swing outward, press in ring, the shovel knife scooping up material to between grinding roller and grinding ring, due to the roller rolling rolling material crushing.

Ball mill for horizontal cylindrical rotating device, material composed of feeding device through the hollow shaft spiral evenly into the mill first warehouse, the warehouse has ladder plate or corrugated plate, and is equipped with different specifications of the steel ball, cylinder rotation will generate centrifugal force after the ball to a certain height, pounding on the material and grinding. After the material is roughed up in the first warehouse, it enters the second warehouse through the single-layer compartment plate, and the material is further ground in the warehouse. The final powder is discharged through the discharge grate, and the powder is finished.
