Description

Technical Field

[0001] The utility model relates to the technical field of coal mills, in particular to a slag discharge device for a coal mill. Background Art

[0002] Coal mill is a machine that breaks coal blocks and grinds them into coal powder. It is an important auxiliary equipment for coal powder furnace. There are vertical mills, high-pressure roller mills, medium-speed micro-powder mills, super-pressure trapezoidal mills, Raymond mills and other models. The coal grinding process is the process of coal being broken and its surface area increasing. To increase the new surface area, the binding force between solid molecules must be overcome, so energy is consumed. Coal is ground into coal powder in the coal mill, mainly through three methods: crushing, breaking and grinding.

[0003] Common coal mills require a slag discharge structure for slag discharge during use. Traditional slag discharge structures are prone to blockage during the slag discharge process, which is not conducive to slag discharge. In addition, the direction of the slag discharge port cannot be adjusted, making it inconvenient for staff to collect and process the slag. Utility Model Content
