A discharging screen contains a receiving plate and a frame with grates fixed on it, which create the working surface of screening, each of which rests on elastic element, it has variable lining executed with possibility of displacement and located in fan-shaped manner to each other with formation in the direction of motion of material clearance, which is expanded. Receiving plate is made in the form of a chute with longitudinal cuts, in which the grates are located, and is located at sharp angle to the working surface of grates. The end part of the chute projects beyond the limits of the frame in the form of console, and longitudinal cuts are made on smaller length than the length of console. In this case, the end part of the grates in the longitudinal section has a form of parabolic curve, and the elastic element of each grate is located in the upper part of the discharging screen under receiving plate.
