Abstract: Mixtures of particulate material of widely different particulate sizes segregate on storage, smaller particles falling to the bottom. In the invention mixture is supplied to a bunker in a plurality of layers and subsequently withdrawn so that mixture is taken from each layer simultaneously. Apparatus used comprises a rotor dividing the bunker into several equal compartments. During introduction of a batch of mixture to the bunker the rotor is rotated through several revolutions so that the mixture forms layers in each compartment. The bottom of the bunker is flat. An outlet slot in the bottom extends along a chord. A crew conveyor below the slot carries mixture falling through the slot away from the bunker. The rotor rotates slowly during dispensing in synchronism with the conveyor, pushing mixture to the slot at such a rate that material from every layer in a compartment falls into the slot simultaneously, the compartments being progressively emptied.
