Particles of molasses absorbed in diatomaceous earth, blended with powdered additives, are dispensed smoothly, without agglomeration or classification according to particle size, by a gravity-fed dispenser having a slowly rotating paddle wheel at the lower front edge of a hopper having a planar front wall and a steeply sloping bottom.

A dispenser for particulate material which becomes sticky and agglomerates when subjected to shearing forces, comprising in combination: an enclosed hopper having a generally planar front wall, a generally rectangular opening in a lower portion of said front wall, a floor sloping downwardly and forwardly at an angle of at least about 60°to the horizontal, extending from the rear of said hopper to a line parallel to said front wall and spaced rearwardly of said opening, said floor then bending forward in a smooth curve to a substantially horizontal plane and terminating at the lower edge of said opening, a stub portion of said front wall, constituting a vertically adjustable lift gate, extending downwardly and rearwardly a short distance into the hopper from the upper edge of said opening and terminating in a distal edge, rotatably mounted in said hopper, an impeller having a horizontally disposed shaft in a plane parallel to said front wall, said impeller being positioned below the distal edge of said stub portion, above the floor and forward of the lower edge of said opening, a plurality of paddles extending generally radially from said shaft along substantially the entire width of the hopper, the the radial length of said paddles being such as to slightly clear the distal edge of said stub portion, and means for slowly rotating said impeller in a direction such that said paddles move from top to bottom when viewed from the outside of said opening.
