Problems solved by technology

[0014] Through analysis and demonstration, it is known that there are three main reasons for the low clinker strength: ⑴ poor cooling effect of the grate cooler; ⑵ poor coal quality; ⑶ burning industrial waste
[0015] In the process of realizing the present invention, the inventors found that there are at least defects such as poor cooling effect, unreasonable proportioning and low calcination temperature in the prior art

Embodiment Construction

[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] According to an embodiment of the present invention, a method for improving the 28-day strength of clinker is provided, including:

[0037] a. Adjust the temperature and humidity of the clinker processing site; step a specifically includes:

[0038] Install a water spray atomization device at the tail of the grate cooler to cool the clinker;

[0039] Regularly clean the throttle valve of the grate cooler to make it ventilated smoothly;

[0040] B, adjust coal raw material, the parts by weight of each component in the coal raw material after adjustment is:

[0041] Coking coal: 30 parts;

[0042] Fat coal: 20 parts;

[0043] Anthracite: 25 parts;

[0044]...

Abstract

The invention discloses an improvement method for 28d strength of a clinker. The method comprises the steps that the temperature and the humidity of a clinker processing site are adjusted; raw coal is adjusted, wherein the adjusted raw coal comprises the following components in parts by weight: 30 parts of coking coal, 20 parts of fat coal and 25 parts of anthracite coal; and industrial waste is adjusted. The improvement method for the 28d strength of the clinker can overcome the defects of poor cooling effect, unreasonable mixture ratio, low calcination temperature and the like in the prior art, and realizes the advantages of good cooling effect, reasonable mixture ratio and high calcination temperature.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for improving the 28-day strength of clinker. Background technique [0002] The 1# production line of my branch factory is responsible for the production of special cement clinker for the entire group company. Clinker is the main component of cement. If you want to grind high-quality cement, you must have high-quality clinker. Therefore, the clinker should be improved first. the quality of. The 28d strength of clinker is one of the very important indicators in clinker quality. The improvement of clinker 28d strength will help us add more admixtures in cement production and reduce the cost of cement. Therefore, we decided to "improve clinker 28d strength" is our research project. [0003] The main technological process of cement production, see figure 1 . The strength of clinker 28d is low and can only reach about 56-57Mpa. For the current situation investi...
