The DRW-400 dredger and the GrAT-400/40 pump is designed for use in mining and processing plants and mining and metallurgical plants, thermal power plants, cement plants, diamond mining and gold mining enterprises, technological lines for crushing, mineral processing and similar industries.
Provided that the length of the pipeline is 200 meters and the conventional geodetic lift is not more than 5 meters, this model nominally produces 60 m3/h or 600 m3 per 10 hours of operation. With a sand density of 1.4 tons per m3, the weight of the extracted sand will be 840 tons.
The energy consumption for extraction of 840 tons of sand will be 600 kWh per 10 hours. Nominal consumption of diesel fuel for 10 hours of operation 600 kWh x 0,210 l / kWh = 126 liters. From this calculation we conclude: To extract 840 tons of sand, should be used 126 liters of diesel fuel is needed. Fuel costs per ton of production of sand is 126 liters / 840 tons = 0.150 liters per ton.
