Embodiment

[0026] The coal deep processing method and the coal treatment method of the embodiments of the present invention will be described in detail below.

[0027] Please refer to figure 1 This embodiment provides a coal deep processing method, which includes screening and grading raw coal 100 through a screen 201 to obtain a coarse oversize 110 and a coarse undersize 120 . Then, the coarse screen oversize 110 and the coarse screen undersize 120 are further subdivided to obtain more commercial coal varieties. The particle size of the screen 201 is 10-30mm, preferably 10-15mm, more preferably 11-14mm, most preferably 13mm. Specifically include the following steps:

[0028] 1. Screening of coarse sieve 110

[0029] The coarse sieve material 110 is sorted by the jig 202 to obtain the first clean coal 111, the first medium coal 112 and the first gangue 113, wherein the first clean coal 111 is further screened into lump clean coal 114 and fine coal. The clean coal 115, lump clean coal...

Abstract

The invention relates to the field of coal processing technology and provides a coal deep processing method and a coal processing method. The coal deep processing method includes the steps that raw coal is screened and graded through a screen net, and crude oversize products and crude screen underflow are obtained; the crude oversize products are separated through a jigging machine, first clean coal, first middle coal and first gangue are obtained, the first clean coal is divided into block clean coal and powder clean coal, and the block clean coal, the powder clean coal, the first middle coaland the first gangue enter a block clean coal bin, a powder clean coal bin, a middle coal bin and a gangue bin correspondingly to be warehoused; the crude screen underflow is subjected to dressing bywashing through three product hydrocyclones so that second clean coal, second middle coal and second gangue can be obtained; the second clean coal is combined into the powder clean coal bin to be warehoused; the second middle coal is combined into the middle coal bin to be warehoused; and the second gangue is combined into the gangue bin to be warehoused. By means of the coal deep processing method and the coal processing method, the variety of commercial coal is greatly increased, the product stability is high, and economic benefits of enterprises can be increased easily. Besides, the coal processing method can be used for performing deep processing on the raw coal so that the variety of the commercial coal can be improved.

Description

technical field [0001] The invention relates to the field of coal processing technology, in particular to a coal deep processing method and a coal treatment method. Background technique [0002] Coal processing refers to the processing of raw coal by various methods in order to improve coal quality or coal utilization value to obtain commercial coal or coal products suitable for different needs. Among them, coal processing includes the screening of raw coal, but the screening process of raw coal in the prior art is simple, resulting in large changes in coal quality, high gangue content, and poor stability. The price of coal has dropped again and again, so that the profits of enterprises have decreased and their credibility has decreased. Contents of the invention [0003] The purpose of the present invention is to provide a coal deep processing method, which can increase the variety of commercial coal, improve product stability, and improve enterprise economic benefits. ...
