Abstract

The invention belongs to the technical field of coal mining equipment, and particularly relates to a secondary crushing system for mineral coal briquettes, which comprises a first box body, wherein two supporting holes are formed in the first box body in the width direction, a transmission mechanism is arranged in the first box body, a second box body is fixedly connected to the lower portion of the first box body, a cylindrical crushing chamber is arranged in the second box body; and a crushing mechanism is arranged in the cylindrical crushing chamber, and a dust collection mechanism is arranged outside the second box body. Supporting parts are fixedly connected to the two sides of the box body. The secondary crushing system can finely crush coal briquettes for many times during use, so that the crushing effect of coal briquettes is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of coal mine equipment, and in particular relates to a secondary crushing system for mineral coal blocks. Background technique [0002] The coal block crusher is to fully break the large block of coal by bumping, bumping, smashing, etc., so that it is convenient for transportation or transshipment. The existing coal crushing device generally can only crush the coal once, the continuous crushing performance is poor, the crushing efficiency is low, and there are still some relatively large coal residues in the crushing process, which cannot crush the coal well into Coal pieces that meet the requirements. Contents of the invention [0003] The object of the present invention is to propose a secondary crushing system for mineral coal lumps aiming at the above-mentioned problems existing in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solut...
