Hydraulic miner with dewatering of peat in travelling magnetic field

The article describes the experimental studies on intensified dewatering of peat treated by magnetic field. The magnetic treatment patterns and magnetic susceptibility of peat pulp are revealed, and the permeability and chemical composition of water in the pulp is examined. The physical simulation data on initial dewatering of a thin destructured peat layer are presented with the found efficient squeezing pressure. The watered peat cutting technology and equipment using a suction-tube dredger in a tandem with a float peat cutting and processing system are presented, including a water content reduction plant with layer-wise mechanical pressing of peat. The plant performs initial dewatering of peat immediately aboard the float system without haulage of over-watered material. Based on the tests, the size of the press-and-drain pans for the peat dewatering plant is selected, and the efficient height of the pile of the pans is substantiated to ensure the preset quality of the product directly aboard the float system.
