Coal Recycling After Crushing And Grinding

After being crushed, the coal is elevated to the belt conveyor and sent to the raw coal bin further. Then the coal is fed into the grinding cavity of LM130M vertical mill by quantitative belt conveyor. After being ground, the coal gets pulverized and enters to the anti-explosive impulse dust collector in the wake of powder separation.

Micro shape of coal particle and crushing energy

2018-11-1  Usually a certain amount of energy would be consumed to fragment a solid. Assuming that crushing a coal block of size D into smaller components of size d, then we can define the reduction ratio i as follows: (6) i = D d. Eq. implies that the greater the i is, the larger the energy is needed for crushing. The theory of new surface formation states that fragmentation of a solid results in new surface formation, and hence the consumed energy in solid crushing
