Superfine ball mill

Abstract

The invention provides a superfine ball mill, and belongs to the technical field of ball mills. The superfine ball mill comprises a base, a ball milling cylinder is rotatably arranged above the base, a driving mechanism used for driving the ball milling cylinder to rotate with the central axis of the ball milling cylinder as the center is arranged between the base and the ball milling cylinder, a feeding port and a discharging port are formed in the two ends of the ball-milling cylinder correspondingly, no less than three screening mechanisms are evenly arranged inside the ball-milling cylinder in the length direction of the ball-milling cylinder, each screening mechanism comprises a material blocking ring and a screen connected to the side wall of the side, close to the discharging port, of the material blocking ring, a plurality of screen holes are evenly formed in each screen, and the apertures of the screen holes are sequentially reduced from the feeding port to the discharging port. According to the superfine ball mill, the fineness of materials can be controlled, the materials can pass through the corresponding screen holes only after the fineness reaches the standard, it is guaranteed that the fineness of the materials flowing out of the discharging port finally reaches the superfine standard, the situation that secondary grinding is needed due to the fact that the final fineness of the materials is not enough is avoided, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to an ultrafine ball mill. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials 52555, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials . Ball mills are suitable for grinding various ores and other materials, and are widely used in mineral processing, building materials and chemical industries. They can be divided into dry and wet grinding methods. According to different ore discharge methods, it can be divided into grid type and overflow type. [0003] The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a ...

Problems solved by technology

However, the fineness of the ground material is difficult to control. If the fineness is not enough, secondary grinding is required, which wastes time and low work efficiency. Therefore, an ultrafine ball mill is needed to overcome the above problems.
