Coking coal moisture control method and hammer crusher for realizing same

Abstract

The invention relates to a coking coal moisture control method and a hammer crusher for realizing the same and belongs to the technical field of coking coal pretreatment methods and equipment of coking plants. In order to solve the main technical problems, the characteristic that the moisture content and the granularity of coking coal are in inverse proportion approximately is bound to be mastered and used fully, and after rough distribution of the coking coal according to the granularity of the coking coal, drying of thin portions of the coking coal is continued, so that drying effectiveness is improved. The coking coal moisture control method is characterized by including: adopting the hammer crusher, wherein hot air is fed into the hammer crusher; performing distributing operation for crushed coking coal; and mixing the distributed coking coal and then conveying the mixed coking coal to a coke oven. The hammer crusher is characterized in that the hammer crusher is provided with a second outlet for the coking coal. The coking coal moisture control method and the hammer crusher for realizing the same are applicable to moisture control of the coking coal and have the advantages of simplicity, feasibility, energy and investment saving and the like.

Description

technical field [0001] The invention relates to a method for adjusting humidity of coking coal and a hammer crusher for realizing the method, and belongs to the technical field of coking coal pretreatment methods and equipment in coking plants. Background technique [0002] Since the humidity control of coking coal has many advantages, such as significant energy saving, improvement of coke yield and quality, etc., more and more coke manufacturers pay attention to it. [0003] In the existing technical field of humidity control of coking coal, the method of removing moisture from coking coal is usually completed by crushing the coking coal after coal blending, and then adopting an independent dehydration process. For example, some manufacturers use a drum-type drying process, and some manufacturers use a fluidized-bed drying process and so on. [0004] The major disadvantages of the prior art are: [0005] 1. Failure to grasp and utilize the characteristic that the water co...

AI Technical Summary

Problems solved by technology

[0005] 1. Failure to grasp and utilize the characteristic that the water content of coking coal is roughly inversely proportional to its particle size, but to dry them together without distinction, which not only affects the drying effect, but also leads to waste of energy

[0006] 2. Failure to grasp and utilize the violent impact and tumbling effects of coking coal during the pulverization process, wasting the opportunity to dry coking coal

[0007] 3. It occupies a large area, and the initial investment and operating costs are relatively high
