Mechanical Knowledge Base: Wheel Mill

The equipment consisting of grindstones and millstones as the main working components is broken (powder) broken or mixed.

The equipment that is broken (crushed) is called a dry mill. For example, a rotary table roller mill has a pair of grinding wheels and a grinding wheel, and the material is ground and crushed on a rotating grinding disk. The outer ring of the mill plate has sieve holes and the crushed material is discharged from the sieve holes. In the refractories industry, it is mainly used to break (powder) broken medium hardness clay, clinker, silica and so on. It is generally used to crush and crush materials. The product crushed with this dry mill is approximately spherical and its corners are not sharp. Dry mill construction is relatively simple, manufacturing and maintenance easier, the feed size requirements are not strict, but the energy consumption is large, the production efficiency is low.

As a mixed equipment, it is called a wet mill. Its structure is similar to that of a dry mill except that there is no sieve on the mill pan, the mill is lighter, and there are unloading mechanisms. The batch material and water are added into the mill, and after being uniformly mixed, the material is discharged by a unloading mechanism. In the mixing process, there is both stirring and squeezing effect, which can better eliminate the air between the particles of the material, so that the water content of the mixed material is uniform, the surface of the particles is fully wetted, and the kneading effect is good, but the granularity of the material is certain. The destructive effect. Wet milling machines are relatively bulky, have lower yields, and consume more energy, but the quality of the clay material is good.
