Multi-stage coal mill for coal processing

Abstract

The invention discloses a multi-stage coal mill for coal processing, which belongs to the technical field of coal processing, and comprises a bottom plate, a main assembly of a coal mill is installed above the bottom plate, and a pulverizer is installed on one side of the main assembly of the coal mill. Assemblies, a plurality of supporting legs are installed on the lower edge of the crushing assembly, and a drying device is installed above the crushing assembly, and the drying device includes a top cover, a spray hopper, an air delivery chamber, a cylinder, a connecting frame, and a socket , heating plate, heat conduction shell, drying frame, connecting pipe, processing box, electric heating rod, mounting plate, silica gel desiccant, mesh tube and fan; The socket, heating plate, heat conduction shell, drying frame, connecting pipe, processing box, electric heating rod, installation plate, silica gel desiccant and mesh cylinder enable the coal pulverizer to effectively dry the coal block, thereby improving the efficiency of the coal pulverizer practicality.

Description

technical field [0001] The invention belongs to the technical field of coal processing, and in particular relates to a multistage coal mill for coal processing. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground through complex biochemical and physicochemical changes. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. [0003] The Chinese patent application number is CN201921351344.1, which discloses a multi-stage coal mill for coal processing. First, the crushing device is used to crush the coal block, and then it is crushed into smaller particles before grinding. The grinding efficiency is greatly improved, and a cleaning net is installed. Mechanism, the brush inside the cleaning mechanism is in a non-rotating state when the filter plate rotates, so the brush can clean the non-standard coal powder...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following problems: 1. The above-mentioned patents have the problem of being unable to effectively dry the wet coal lumps before being crushed, which leads to the fact that the coal lumps are easily rebonded after being crushed, and the inside of the crushing box is easily damp. This further reduces the practicability of the coal mill; 2. The above-mentioned patent has the problem that the primary crushing mechanism and the coal mill cylinder are difficult to separate when needed, thus reducing the convenience of the coal mill
