Description

Continuous Ball Mill

technical field

The utility model relates to the technical field of continuous ball mills, in particular to a continuous ball mill device.

Background technique

During the grinding process of the continuous ball mill, the material processing and production are continuous, and the input and output are continuous. It can be produced in two forms: open circuit and closed circuit. The open circuit work does not need to strictly control the product particle size, and the processing capacity is large. It is to re-grind the materials that do not meet the particle size of the finished product through the feeding device. Most of the ball mills produced are continuous ball mills, which have the widest application range. The material hollow tube enters the grinding cylinder for grinding, and then is discharged from the discharge hollow tube on the other side of the grinding cylinder, so as to realize the continuous crushing and grinding of the material. The application number is "201721255790.3". , which has solved the problem of the existing continuous ball mill due to the large overall mass of the ball mill and the material, the end cover of the ball mill is a casting, and the load-bearing parts at both ends will be worn for a long time, the manufacturing and maintenance costs are high, and the ball stones in the continuous ball mill And the raw material cannot be higher than the central axis of the cylinder, which limits the efficiency of the ball mill. After further searching, it is found that the "impact continuous ball mill" disclosed by the application number "201420419287.7" is set through a specific technical structure. It effectively solves the problem that most of the currently used ball mills use closed-circuit circulation grinding, which has low efficiency and high energy consumption. To solve the problem of closed-circuit circulation grinding, a closed-circuit impact mill design has also appeared. Although the efficiency of the closed-circuit impact mill is improved, the energy consumption is also reduced. However, most of them will have technical disadvantages such as short service life of the ball mill cylinder and insufficient grinding. However, there are still many defects in the continuous ball mill device with similar structure in actual use, such as: the continuous ball mill device miscellaneously grinds the materials Incomplete grinding is prone to occur, and some large-size particles will be entrained in the grinding material, which will affect the overall quality of the grinding material. At the same time, the continuous ball mill cannot automatically perform secondary grinding on the substandard particles in the grinding product. In view of this, we propose a continuous ball milling device.
