Conditioning apparatus for handling particulate material comprises a central frame and a plurality of spaced, annular troughs mounted to the central frame to support the particulate material. The troughs are arranged in a stacked configuration having successive pairs of upper and lower troughs with an uppermost trough for receiving the particulate material and a lowermost trough for discharging particulate material. Hydraulic cylinders or other suitable means are used to impart vibratory movement to the plurality of troughs to fluidize and advance the particulate material in a first direction on each of the plurality of troughs. A passage is formed through each trough for particulate material to fall from the upper trough of a pair to the lower trough. The passage of the upper trough is non-aligned in a vertical plane with the passage of the lower trough such that particulate material falling from the upper trough is received on the lower trough to travel in the first direction over the distance of the lower trough before reaching the passage of the lower trough. A mixing surface is provided in each passage to promote tumbling and mixing of the particulate material which tends to ensure that all surfaces of the particulate material are exposed and available for the conditioning process. The conditioning apparatus finds particular application in drying of particulate material by passing drying gas through the fluidized material, or in filtering or scrubbing of gas by passing the gas through fluidized particulate material.
