Mill capable of improving mixing amount of road cement mineral powder

Abstract

The invention discloses a mill capable of improving the mixing amount of road cement mineral powder. The mill comprises a first sorting sub system, a second sorting sub system, an activated arc current-limiting ring and a special discharge system for a sorting mill, which are connected sequentially; the special discharge system for the sorting mill is internally provided with abrasion-resistant multi-element alloy micro forged pieces. The mill capable of improving the mixing amount of the road cement mineral powder can overcome the defects of unreasonable mill grading, poor metering accuracy, low clinker intensity and the like in the prior art so as to achieve the advantages of reasonable mill grading, good metering accuracy and high clinker intensity.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a mill for increasing the amount of mineral powder in road cement. Background technique [0002] In 2013, due to the needs of the expansion project of Liuzhou Airport, our company began to mass produce road cement. Considering the fierce competition in the cement industry, reducing production costs is the only way out for the enterprise; at the same time, the granulated blast furnace slag powder produced by the slag vertical mill of our company's #4 production line has a large surplus, and the mill is often stopped when the storage is full, and the mill operation rate is low. In order to make full use of the capacity of the vertical mill, the company requires the 1# production line to be mixed with granulated blast furnace slag powder (referred to as slag powder) to produce road cement after passing through the homogenizer. [0003] The 1# production line of Guangxi Yu...

AI Technical Summary

Problems solved by technology

From June to October 2013, the strength of clinker reached 55MPa in only one month, and the strength of clinker was relatively low

[0015] Determination of reasons: 1. Unreasonable mill gradation; 2. Inaccurate measurement; 3. Low clinker strength

[0016] In the process of realizing the present invention, the inventors found that there are at least defects such as unreasonable mill gradation, poor measurement accuracy and low clinker strength in the prior art
