The shape and structure of the dry ball mill
As we all know, the grinding method of ball mill
is divided into dry grinding method and wet grinding method. The ball mill using dry grinding method is called dry ball mill. Its appearance is similar to that of other ball mills, and the structure is similar. Let us one below. Get up and understand its structural composition.
The structure of the dry ball mill is composed of a feeding device, a discharging device, a grinding device, a transmission device and the like, wherein the feeding device is composed of a feeder, a feeding screw, a bearing cover, a bearing seat, a roller and a slate. The discharging device is composed of a discharging jaw, a guiding sleeve, a flange, a material guide and a discharging sieve, and the grinding device is composed of a cylinder body, a lining plate, a grinding medium, a grinding chamber, a unidirectional passing sieve, and the like, and the transmission device It consists of a reducer, a pinion, a coupling, and a base.
The large-scale mining equipment consisting of various parts and parts—the dry ball mill is the big one in the horizontal cylinder in the picture below. It looks cumbersome and big, but it works unambiguously. Here is its work. At the scene, let's take a look.
Dry ball mill production site
Dry ball mills are more common in cement production. Because the raw materials of cement react with water and chemically affect the quality of finished cement. Other materials that are easily reacted with water are generally dry if not required. The ball mill is ground, so the dry ball mill and the wet ball mill cooperate with each other, and almost cover the material grinding work of the entire mine beneficiation industry. The two machines complement each other, and the mining industry is the machine (ball mill)!
The reason why the dry ball mill can be used in the mining and dressing industry in large quantities is equal to that of the wet ball mill. We know that the wet ball mill has more processing capacity than the dry grinding, and the wet ball mill is more environmentally friendly and less dusty. What is the advantage of the dry ball mill to compete with it?
1. The dry ball mill grinding material has a relatively low pulp surface and has a forced discharge effect, which can effectively reduce the over-grinding or muddy phenomenon of the mine materials, accelerate the discharge rate and improve the grinding efficiency;
2. When the dry ball mill is ground, the material is in a dry state, no need to dry and other operations, which greatly saves production cost and simplifies the operation process.
