Description

technical field [0001] The invention relates to the field of coal processing, in particular to a grinding device for coal powder processing. Background technique [0002] Coal powder is a kind of coal product made of washed coal, coking coal, etc. after screening, drying and grinding. It is mainly used for the molding of green sand in blast furnace smelting and casting. Coal powder is added to green sand for cast iron to prevent Sand sticking defects on the surface can improve the surface finish of castings, reduce sand inclusion defects, improve the collapse function of molding sand, and effectively prevent subcutaneous pores for wet ductile iron parts. [0003] Grinding is an important process in the processing and production of coal powder. The grinding quality and efficiency of the existing grinding devices are not high, and it is difficult to achieve continuous feed grinding, which greatly affects the production efficiency. Contents of the invention [0004] The obje...
