Second, the main equipment of each process is:
1, coal mining: mainly including shearer, scraper conveyor (commonly known as forward and backward sliding), hydraulic support, crusher, transfer machine, emulsion pump station, etc.
2. Transportation: Belt transportation mainly includes belt conveyors and coal feeders. If coal is transported by hoisting, there are mainly hoists, skips (vertical shaft hoisting) and harvesters (inclined shaft hoisting). Belt transportation is more common in coal mines now.
3. Washing: At present, dense medium coal preparation is the main equipment, including dense medium shallow trough separator, spiral separator, medium removal screen, slurry pump, filter press, filter press, thickener, fan and centrifuge.
4. Loading: quantitative bunker, coal feeder, etc.
5. Outbound transportation: mainly cars and trains.
