Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, specifically to a coal grinding device. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. Coal grinding is a device used to grind coal into powder, mainly used for the production and processing of coal powder. It crushes and grinds coal into the required coal powder through physical methods. Currently, coal is the main fuel for thermal power generation. However, in order to ensure the complete combustion of coal, coal is generally crushed into coal powder, and then flame retardants are added to ensure the complete combustion of coal and reduce the emission of harmful gases. However, traditional coal crushers are relatively coarse, and the crushed particles are uneven, which does not meet the requirements for complete combustion.

[0003] For example, CN201520713419.1 discloses "A Novel Coal Piece Crushing and Grinding Device", which uses crushing rollers to perform primary crushing of large coal lumps, and then performs secondary crushing and screening through fine crushing pendulum balls to ensure that the coal powder is of uniform size, reduce the trouble of subsequent sewage treatment, and is convenient and practical.

[0004] In traditional coal grinding, coal lumps are crushed and ground using grinding equipment. However, general coal grinding equipment can only grind coal lumps to a single coarse or fine size. Coal powder, on the other hand, requires different subsequent processing steps when used, which reduces the practicality of coal powder. Utility Model Content
