The invention relates to a particle mixture and the stabilization of a homogeneous distribution of these particles in the mixture. In each case, at least two wall parts over-lap in conveying direction at least partly in a fan-like manner at a top side remote from the conveying face. The voltage source is separately coupled to the discharging loop and the controller in order to supply electric power to the controller. The implement includes no ground engaging tool in the right path between the front right portion and the rear right portion, and no ground engaging tool in the left path between the front left portion and the rear left portion.
