Superfine grinding system for producing cement

Abstract

The invention relates to the field of cement producing and processing, in particular to a superfine grinding system for producing cement. The superfine grinding system comprises a supporting frame anda grinding barrel, wherein the grinding barrel is sequentially provided with a feeding channel, a shutter mechanism, four groups of coarse grinding and breaking mechanisms, a fine grinding mechanism,a reversal grinding and driving mechanism and a discharging groove from top to bottom; the shutter mechanism comprises a plurality of moving plates which can be opened and closed; the coarse grindingand breaking mechanisms comprise grinding rollers capable of rotating; a screening plate is horizontally arranged between the coarse grinding and breaking mechanisms and the fine grinding mechanism;a base is horizontally and fixedly arranged below the supporting seat; the reversal grinding and driving mechanism comprises a driving gear capable of rotating and a transmission rod; and a funnel blanking frame is arranged at the top end of the feeding channel. According to the superfine grinding system for producing the cement, disclosed by the invention, a series of operations such as feeding,heating, breaking and superfine grinding can be realized through the grinding barrel, so that production procedures are reduced, the working efficiency is greatly improved, the labor intensity is reduced and the production cost is also reduced.

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
