The cost of the sand washing plant mainly includes equipment cost and construction cost, and environmental protection cost. device [blasting equipment] rock drills, drilling rigs, wind guns, etc.; [transportation tools] forklifts, trucks, excavators, loaders, dump trucks, etc.; [Sand making equipment] The production of stone materials is inseparable from the feeder, crusher, vibrating screen and belt conveyor. Sand making machine and sand washing machine . [Electrical system] motor, starter cabinet, cable, transformer, air compressor, etc. Civil engineering The civil works and steel structures of the stone factory's workshops, silos, crushers, vibrating screens and belt conveyors also require a corresponding budget. Usually the price is about 10% of the equipment cost. Environmental cost Environmental protection is the general direction of the stone factory. After many governments have clearly requested environmental protection, they can only be put into operat

When the filter cake needs to be washed, there are clear flow one-way washing and two-way washing, dark flow one-way washing and two-way washing. A. The clear flow one-way washing is that the washing liquid enters sequentially from the washing liquid inlet hole of the thrust plate, passes through the filter cloth and then passes through the filter cake, and flows out from the non-porous filter plate, at which time the liquid discharging nozzle of the orifice plate is closed. In the state, the outlet nozzle of the non-porous plate is open. B. The clear flow two-way washing is that the washing liquid is washed twice from the washing liquid inlet holes on both sides above the thrust plate, that is, the washing liquid is washed from one side and then from the other side, and the outlet of the washing liquid is the same as the inlet. The direction of the corner, so it is called two-way cross washing. C. The dark flow unidirectional flow is that the washing liquid enters the perfor
