Ball mill cylinder for ultra-finely grinding slag, fly ash and cement

Abstract

The invention relates to a ball mill cylinder for ultra-finely grinding slag, fly ash and cement. The ball mill cylinder comprises a cylindrical cylinder body, two limiting devices, one or more movable separating mesh discs and one or more disc shifting devices; a feeding inlet and a discharging outlet are formed in the two sides of the cylindrical cylinder body correspondingly, and a disc shifting channel is further formed in the axial direction of the cylindrical cylinder body; the two limiting devices are arranged in the cylindrical cylinder body and located on the two sides of the disc shifting channel; the one or more movable separating mesh discs are arranged in the cylindrical cylinder body, are located between the two limiting devices, can move in the cylindrical cylinder body in the axial direction of the cylindrical cylinder body, and are used for separately grinding the materials; and the one or more disc shifting devices comprise disc shifting power sources and shifting rods. According to the ball mill cylinder, by arranging the movable separating mesh discs, the grinding area between the materials of the slag, the fly ash and the cement, and the like and a grinding ball is increased, the grinding time between the materials of the slag, the fly ash and the cement, and the like and the grinding ball is prolonged, and thus the grinding efficiency of the ball mill cylinder for ultra-finely grinding the slag, the fly ash and the cement is improved.

Description

technical field [0001] The invention relates to a ball mill cylinder, in particular to a ball mill cylinder for superfine grinding of slag, fly ash and cement. Background technique [0002] Ball mills for cement, fly ash, slag, etc. have the characteristics of strong adaptability to materials, continuous production, large crushing ratio, and easy control of the fineness of grinding products. The working principle of the commonly used cement ball mill is that the material enters the mill chamber spirally and evenly through the feeding hollow shaft from the feeding device. There are stepped lining boards or corrugated lining boards in the chamber, and steel balls of different specifications are installed inside, and the cylinder rotates to produce Centrifugal force brings the steel balls to a certain height and then falls, impacting and grinding the materials. [0003] Especially the ball mill grinding balls of cement, fly ash, slag, etc. are the grinding material medium of t...

AI Technical Summary

Problems solved by technology

[0004] The technical solution adopted in the prior art is to improve the fineness of fly ash and cement by improving the grinding balls of the ball mill, but the effects are not very satisfactory, and the cement, fly ash, slag, etc. The ball mill for materials mainly has low grinding efficiency, and the diameter of the ground particles is relatively large, which cannot meet the requirements of existing construction and mineral extraction. Therefore, an improved ball mill is urgently needed to make slag, fly ash, cement and other materials. Get effective and fine grinding, and improve grinding efficiency
