Description

technical field

[0001] The invention belongs to the field of coal slime drying, and in particular relates to a coal slime drying treatment device. Background technique

[0002] In the production of the dressing plant, the by-product coal slime has high water content, low calorific value, and low economic benefits. Therefore, it is necessary to dry the coal slime to increase its calorific value, thereby improving economic benefits.

[0003] Conventional drying technology is likely to cause problems such as uneven heating of coal slime, overheating and decomposition of the outer layer, and insufficient drying of the inner layer. It is impossible to fully dry the coal slime, and it is easy to cause waste of heat energy. Contents of the invention

[0004] In view of the above analysis, the present invention aims to provide a coal slime drying treatment device, which solves the problems of uneven heating of coal slime, overheating and decomposition of the outer layer, and insuf...
