Cement clinker grinding implementation equipment and stirring device thereof

Abstract

The invention discloses cement clinker grinding implementation equipment, and relates to the technical field of grinding devices. The cement clinker grinding implementation equipment comprises a shell, a rotatable stirring shaft, stirring units, a screening device and reinforced stirring parts, wherein the stirring shaft is inserted into a stirring cavity of the shell, the stirring units are arranged on the stirring shaft, the screening device separates the stirring cavity and a discharge port, and the reinforces stirring parts extend in a sub-grinding area; and the reinforced stirring parts are configured to enable at least part of grinding media and materials of the sub-grinding area to do grinding motion in the circumferential direction of the stirring shaft in cooperation with the stirring units. According to the cement clinker grinding implementation equipment, dry grinding can be carried out under the conditions of high filling ratio and high rotating speed, the dead mass zone iseffectively eliminated, and the energy consumption is greatly reduced under the condition of grinding the materials with the equal magnitude.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to cement clinker grinding equipment and a stirring device thereof. Background technique [0002] The high-energy ball mill is the core equipment of the crushing and grinding process. The drum-type ball mill mainly used in industry has a large processing capacity, but it has a critical speed and the collision energy is small during ball milling. The cylinder part of the stirring ball mill is fixed, and the agitator rotates at high speed with the main shaft. Under the action of friction and centrifugal force, the grinding medium in the cylinder is driven to move together, so that intense and frequent collisions occur between the medium and between the medium and the wall. Shearing and friction, resulting in the crushing and dissociation of materials. In principle, the stirring ball mill has no speed limit, and the collision energy can reach a large value during ball milling...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the existing horizontal ball mill is not suitable for cement clinker dry grinding, especially the problem that the existing horizontal ball mill has a large number of dead material areas under the condition of high filling and high speed. The present invention provides a A kind of cement clinker grinding implementation equipment, which can carry out dry grinding under the condition of high filling rate and high speed, effectively eliminate dead material area, and greatly reduce energy consumption under the condition of grinding materials of the same level
