The invention belongs to the technical field of industrial and agricultural production tools, and particularly relates to a smooth
particle material rolling
drying device. The smooth particle materialrolling
drying device comprises a bottom plate, first supporting legs, second supporting legs, a first rotating roller, a second rotating roller, a conveying belt, a supporting frame, a
heat supply plate, a first hopper, a mounting frame, a connecting plate, a first motor, a discharging roller, a second motor and a material returning mechanism. According to the smooth
particle material rolling
drying device, by the obliquely-arranged conveying belt, when materials fall onto the conveying belt, the materials roll and move downwards under the action of the gravity of the materials; and throughrotation of the first motor, the conveying belt drives the materials to have an upward trend under the action of
friction force; when the materials fall down, the materials are turned over under the combined action of the gravity of the materials and
friction force provided by the conveying belt; and by adjusting the rotating speed of the first motor, the upward
moving speed of the materials driven by the conveying belt is balanced with the downward
rolling speed of the materials under the action of
self weight, the materials stay on the conveying belt for a long time, and a
heat supply platecan dry the materials more evenly.
