Wheel mill: composed of roller and grinding pan, mainly used to crush(smash) materials or mulling.
Dry pan mill, as crushing equipment, such as rotary grinding pan has a pair of roller and grinding pan,materials in the rotate grinding pan is crushed, Outer of grinding pan, there is sieve pore, smashed materials are discharged from the sieve pore. In the refractory industry it is mainly used to crush medium hardness clay, clinker, silica,etc. Commonly used for secondary crushing and fine crushing. Dry pan mill has simple structure, easy manufacturer and maintenance, feeding size is not too strict, but large energy consumption, low production efficiency.
Wet pan mill, as the mixed equipment, its structure is similar to the dry pan mill, but there is no sieve pore in the grinding pan, roller is much lighter, and has discharging mechanism. Add mixtures materials and water into the roller, through muling evenly, discharge from the discharging structure, in the mixing process, there is mixing and extrusion, so can better discharge air between the material particles, making mixed pug and water mixing evenly, particles surface is wetting fully, muling effect is good, but for materials particles has a certain effect. Wet pan mill is relatively heavy, low yield, energy consumption is larger, but mixed pug materials have good quality.
