The DRW-800 dredger and the GRAT 800/40 pump is designed for use in mining and processing plants, mining and metallurgical plants, thermal power plants, cement plants, diamond mining and gold mining enterprises, technological lines for crushing, mineral processing and similar industries.
Economic indicators:
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 120 cubic meters per hour or 1,200 cubic meters per 10 hours of operation. The density of sand is 1.3 tons per cubic meter, the weight of extracted sand is 1560 tons. The extraction costs of 1560 tons of sand will amount to 1,600 kW/h in 10 hours. The nominal consumption of diesel fuel for 10 hours of operation is 1,600 kW/h x 0.226 l/kWh = 361.6 liters. From this calculation, we conclude: To extract 1560 tons of sand, 361.6 liters of diesel fuel is needed. The cost of mining one ton of sand is 361.64 liters/1560 tons = 0.232 liters per ton.
