Coal is a kind of industrial solid waste, waste residue from coal-fired power plants, industrial and civil boilers and other equipment.
1. Crushed and sieved. The specific process is that the large coal gangue is uniformly fed by the vibrating feeder, and conveyed to the coal gangue pulverizer through the belt conveyor for coarse crushing, and the coarsely crushed coal gangue is sieved by the vibrating sieve.
2. Medium and fine. The sieved material in the above process needs to be crushed twice, and the coal gangue conveyed by the conveyor to the counter-breaking or cone-cutting is finely crushed, and then sieved by a circular vibrating sieve, if the particle size is too large for the particle size The larger particles of coal gangue can be returned to the counter-break or the cone to break again.
