Provided that the length of the pipeline is 200 meters, and the usual geodetic elevator does not exceed 5 meters, this model nominally produces 240 cubic meters per hour or 2,400 cubic meters per 10 hours of operation.The density of sand is 1.3 tons per cubic meter, weight The extracted sand is 3120 tons. The cost of extracting 3120 tons of sand will be 2000 kWh in 10 hours. The nominal consumption of diesel fuel for 10 hours of operation is 4000 kW x 0.200 l/kW = 2000 liters. From this calculation we conclude: To extract 3120 tons of sand, 452 liters of diesel fuel is needed. The cost of producing one ton of sand is 452 liters/3120 tons = 0.145 liters per ton. This model is able to transmit pulp at a distance of 500 meters without loss of productivity.
