Abstract

The invention discloses a cement grinding mill activation device, and relates to the technical field of cement ball mills. The cement grinding mill activation device comprises a ball grinding mill lining plate. A plurality of activation cones are fixedly installed on the ball grinding mill lining plate and are further distributed on the ball grinding mill lining plate in a staggered mode. Each activation cone comprises a first triangular plate and a second triangular plate. One side edge of each first triangular plate is connected with one side edge of the corresponding second triangular plate. The base edges of the first triangular plates and the base edges of the second triangular plates are both fixed to the ball grinding mill lining plate. The included angle of the base edges of the first triangular plates and the base edges of the second triangular plates is 70+ / -5 degrees. Edges formed by connecting the first triangular plates and the second triangular plates face the direction opposite to the rotating direction of a ball grinding mill. The first triangular plates and the second triangular plates are both provided with activation holes. In the operating process of the mill, grinding bodies and materials of different particle sizes can be activated through the activation device, and the milling capacity of a fine grinding bin is enhanced.

Description

technical field [0001] The invention relates to the technical field of cement ball mills, in particular to a cement mill activation device. Background technique [0002] Cement mill is an essential and important equipment in cement production. The power consumption of cement grinding is close to half of the comprehensive power consumption of the entire cement production, accounting for a considerable part of the cost of cement production. The degree of grinding is also related to the performance of cement. Therefore, improving the grinding efficiency is something that cement grinding technicians must consider. At present, cement enterprises mainly use ball mills for grinding. Ball mills are generally divided into two chambers, a coarse grinding chamber and a fine grinding chamber. The middle of the coarse grinding chamber and the fine grinding chamber is separated by a partition board. Balls mainly play a role in crushing materials, and the fine grinding chamber is equipped...
