Novel grinding device for dry-process cement production

Abstract

The invention discloses a novel grinding device for dry-process cement production. The novel grinding device is provided with a primary grinding mechanism which can realize primary crushing of materials, and then a secondary grinding mechanism is utilized to thoroughly grind and crush the materials; the secondary grinding mechanism is installed on a swinging and oscillating mechanism so as to be driven by the swinging and oscillating mechanism to swing and oscillate, the swinging and oscillating mechanism can help ground cement blanks in the secondary grinding mechanism to be discharged out of the secondary grinding mechanism, the grinding efficiency is effectively improved, and the problems that the ground materials are stuck and jammed are solved. According to the novel grinding device, the rotating direction of a center upper grinding seat is the same as that of an outer upper grinding seat, the rotating direction of the center upper grinding seat is opposite to that of a middle upper grinding seat, therefore, the grinding effect can be effectively improved, and the problems that the materials are stuck and jammed in the grinding process are solved.

Description

technical field [0001] Specifically, the invention relates to a grinding device for a new type of dry-process cement production, and relates to related fields of cement grinding. Background technique [0002] At present, in the cement production process, most of the raw materials are crushed, such as limestone, clay, iron ore and coal. However, these raw materials have larger particle size and higher hardness after mining. Therefore, the raw materials need to be crushed first, and the crushing process is more economical and convenient than the grinding process. Therefore, it is generally necessary to crush the raw materials before grinding or powdering. Grinding, that is, before the material enters the grinding equipment, the bulk material is broken to a fine and uniform particle size as much as possible, so as to reduce the load of the grinding equipment and increase the output of the mill. [0003] For cement, generally speaking, the finer the powder after grinding, the b...

AI Technical Summary

Problems solved by technology

[0003] For cement, generally speaking, the finer the powder after grinding, the better its performance. However, the current grinding method generally adopts ball milling. This grinding method is not efficient, and the particle size of the powder is difficult to ensure uniformity. However, when the current method of upper and lower grinding discs is used for grinding, it is easy to cause grinding sticking, and it is also prone to unevenness of grinding and blanking, which affects grinding efficiency and reliability.
