A superfine grinding system for cement production

Abstract

The invention relates to the field of cement production and processing, in particular to an ultra-fine grinding system for cement production, which includes a support frame and a grinding barrel, and the grinding barrel is sequentially provided with a feeding channel, a shutter mechanism, and four sets of coarse grinders from top to bottom. The crushing mechanism, the fine grinding mechanism, the reverse grinding drive mechanism and the feeding trough, the shutter mechanism includes several movable plates that can be opened and closed, the coarse grinding and crushing mechanism includes grinding rollers that can rotate, the coarse grinding and crushing mechanism and the fine grinding mechanism A screening plate is installed horizontally between the grinding mechanisms, a base is fixed horizontally under the supporting base, the reverse grinding driving mechanism includes a rotatable driving gear and a transmission rod, and a funnel blanking rack is provided at the top of the feeding channel. The shown ultrafine grinding system for cement production can perform a series of operations such as feeding, heating, crushing, and ultrafine grinding through the grinding barrel, which reduces the production process, greatly improves work efficiency, and reduces manual labor intensity. Reduced production costs.

Description

technical field [0001] The invention relates to the field of cement production and processing, in particular to an ultrafine grinding system for cement production. Background technique [0002] Cement grinding is the final process of cement manufacturing and also the process that consumes the most electricity. Its main function is to grind cement clinker (and retarder, performance adjustment materials, etc.) to a suitable particle size (indicated by fineness, specific surface area, etc.), form a certain particle gradation, and increase its hydration area. Accelerate the rate of hydration to meet the requirements of cement paste coagulation and hardening. [0003] With the development of precalciner kilns becoming more and more perfect, the heat consumption of clinker production has been greatly reduced, while the comprehensive power consumption of cement production has remained high for a long time. In the 1980s, people focused on the improvement and breakthrough of grindi...

Problems solved by technology

[0004] In the existing cement grinding equipment, most of them are prepared by different equipment. The feeding, heating, crushing, grinding and collection are all operated by different devices. This method not only occupies a large area, but also greatly improves the production capacity. cost, and it needs to go through multiple transshipment processes, which increases the production process and affects the efficiency of production and preparation
