Cement dryer is the material heating drying equipment. With the rotary cylinder sleeves listed by the materials for the spiral vane and discontinuous spiral Yang stripper plate between the inside and outside cylinder feeding turn-back and uplift process of getting drying. Listed structure of the sleeve length could make cement dryer dyanmic statistics, due to sharply reduce heat surface, so that the heat consumption is reduced, and the heat transfer area to make double hot result is greatly improved. The material of cannot touch smoke, the inner and outer tube vehiele cement dryers respectively within smokestacks and provide the annular smokestacks, between smokestacks with radial flue communication, similarly high efficiency and energy saving. See not hard, on the thermal material and cold media in terms of the machine be sleeve type rotary cooling machine.
Cement dryer, by two to five cylinder sleeves columns, with the radial support (7) and (25) and so on each other to become an organic whole repeatedly, frame benito wheelset (16) and (17), in which the body is connected in the gear or other transmission system to make the body accept external turn movement, material (20) within each cylinder by spiral vane and intermittent transmission and spiral Yang stripper plate cylinder by and lift up the connected aggregate box (8) ends next makings, heat (21) can be and material (20) mix of flow, touch by aggregate box (8) by top eduction, also can be the cylinder body inside a pipe (29), annular smokestacks (31) and raw mask (33) and communication each smokestacks radial smokestacks (30), (32) by exhaust mouth (34) PaiKou, its features are: (1) inside and outside cylinder (1), (2), (22) with the collar column, the radial support (6), (28) to represent a body, frame in Joe wheelset (16) and (17), (2) each canister contains a spiral leaf (5), (6) and (24) and discontinuous spin Yang stripper plate (3), (4) and (23), (3) in the inner cylinder (1) a hot smokestacks (29), each cone annular smokestacks have between the outermost (31), a mask (33) and raw smoke mouth (34), in (29), (31) and (33) have between radial smokestacks (30) and (32) communication.
