A thrower constructed for the mining industry and comprises a rotatable rotor pivotally connected by means of at least one connecting rod with a bucket adapted to receive and unload material. The spacing of the axis of rotation of the rotor from the axis of rotation of the adjacent pivot of the connecting rod is twice the spacing between the axes of rotation of the two pivots of the connecting rod, parallel with the axis of rotation of the rotor. In operation, the drive of the thrower effects rotation of the rotor and of the connecting rod in the same direction at the same speed, as well as rotation of the bucket in the same direction at a speed which is twice the rotation speed of the rotor. The material is loaded into the bucket in the lower portion of the rotor, since the absolute speed equals zero at this point of its path. The material is thrown the bucket at a predetermined point of its path, the moment the direction of the centrifugal force aligns with the upper open portion of the bucket, the latter being mounted so that it can be adjusted and retained in a preselected position relative to the horizontal plane.
