Abstract
Description
technical field
[0001] The invention relates to a petroleum coke grinding device, in particular to a petroleum coke high-efficiency grinding device for battery production. Background technique
[0002] Petroleum coke is a product obtained by distilling crude oil to separate light and heavy oil, and then thermally cracking the heavy oil. From the appearance, the coke is black lumps (or particles) with irregular shapes and sizes. ), with metallic luster, coke particles have a porous structure, and the main element is carbon, accounting for 80wt% (WT is the English abbreviation of Weight, which means weight percentage. 5WT% is equivalent to more than 50000PPM, and the rest is hydrogen , oxygen, nitrogen, sulfur and metal elements. Petroleum coke has its unique physical, chemical and mechanical properties. It is the non-volatile carbon, volatile and mineral impurities (sulfur, metal compounds, water, ash, etc. ) These indicators determine the chemical properties of coke. [00...
