A controllable method for installing alumina grinding media for ball mills

Abstract

The invention discloses a controllable method for installing alumina grinding media for ball mills, comprising the following steps: (1) selection of alumina grinding media: requiring the grinding media to be corundum ceramic materials; (2) selection and technical transformation of ball mills: selection Ball mill with pre-grinding system; technical improvement before installation of alumina grinding media includes: (a) optimization and technical improvement of pre-grinding system: (b) adjustment of internal structure of the mill: (3) gradation of alumina grinding media Find the most effective grinding body diameter corresponding to various particle size materials on the test mill in the laboratory, and then calculate the grinding body diameter used in actual production, and then obtain the correction coefficient through experiments, and finally improve the existing stage (4) Adjustment of the central control operation method: make the wind speed in the mill 0.8-1.2m / s, maintain a uniform material flow rate in the mill, and stabilize the output of the grinding machine. The method saves energy and reduces consumption, prolongs the service life of the grinding medium, and greatly reduces maintenance workload.

Description

technical field [0001] The invention relates to a ball mill, in particular to a controllable method for installing alumina grinding media for a ball mill. Background technique [0002] At present, ball mill grinding is still the main method of dry grinding of cement, mineral powder, fly ash, stone powder, etc. When ball mill grinding, the metal grinding body is the main grinding medium. [0003] The existing problems are: the mass of the metal grinding body is large, resulting in high drag power of the ball mill, high operating current, and high energy consumption of grinding, so that the power consumption of dry grinding and the wear of the metal grinding body occupy the cost of dry grinding. An important part of this is the inherent difficulty of grinding operations. [0004] In order to solve the above problems, the feasible way now is to replace the metal grinding body with high-quality and wear-resistant new alumina grinding media. [0005] In order to ensure the grin...
