Combination cement grinding system

Abstract

The invention provides a combination cement grinding system. The combination cement grinding system mainly comprises a hoister, a roll squeezer, a first powder concentrator, a third powder concentrator, a ball grinder and a bag type dust collector; the combination cement grinding system mainly comprises two circulating systems, the first circulating system comprises a steady flow bin, a hoister, a roll squeezer, the first powder concentrator and a second powder concentrator; and the second circulating system comprises the second powder concentrator, the ball grinder, the third powder concentrator, two conveyors and the hoister. The finished cement contained in materials extruded by the roll squeezer through the system are separated out, the powder grinding phenomenon of the ball grinder can be reduced, the system yield can be improved, and proved by production, the production of the system can be increased by more than 10%, and electricity consumption is reduced.

Description

technical field [0001] The invention relates to a cement combined grinding system. Background technique [0002] In recent years, with the increasing shortage of energy and rising prices, the production cost of cement manufacturing enterprises is getting higher and higher. Energy saving, consumption reduction and environmental protection have become important issues for the development of each enterprise. In the process of cement production, the power consumption of the grinding link is very large. The power consumption of the traditional grinding process is about 40kwh / t per ton of cement. Cement power consumption is also reduced to about 32kwh / t, accounting for about 35% of cement production power consumption. [0003] How to increase cement mill output and reduce product power consumption under the existing equipment and process conditions has become the research goal of technicians. During the use of cement roller press combined grinding system, our company has carried...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a cement combined grinding system, aiming at the characteristics of the cement roller press combined grinding system, it solves the problem of secondary sorting of finished products of the roller press and the problem of over-grinding due to too much fine powder in the cement mill problems, so as to achieve the purpose of increasing the output and reducing power consumption of the cement grinding system
