This drier is suitable for the raw materials that contain more moisture and appear paste and other raw materials that can not be dried with other drying methods. For example, copolymer of vinyl acetate and chloroethylene, cellulose acetate, catalyst, C,M.C., CT-1 resin, burnt plaster, electrolytic manganese dioxide, anthraquinone ammonium sulphonate, fluor, diatomaceous, silica gel catalyst, born powder, potassium perchlorate sulfonamide, synthesis resin, active argil, chemical filter cake, titanium dioxide, decanedioic acid, copper sulphate, Aluminum sulphate, sodium sulphate, calcium phosphate, starch, dyestuff, calcium citrate, coal earth, cement, aluminum hydroxide, barium hydroxide, slurry of calcium carbonate, residue of sludge, organic compounds, ferric oxide, organic fuel, maize albumen feed, mica powder, medicine, dyestuff, paper pulp of potassium perchromate, lees residue and so on.

Air drier can remove moisture from the surface of raw materials of granule or powder that are easy to dehydrate. Under the air of drying, the quality of finished products can be controlled to the best state because of raw material can stay here in a short time. The drier of our factory is developed on the basis of basic type to add a reinforced device of stepless speed exchange. When the humidity raw material is fed through screw, it is mixed with air fully and under the broken and pushing of rotating knives, the surface of raw material is broken to fine granule. It absorbing of air force. At the place it is dried further. The humidity and heavy granule that is not absorbed by air is broken and dried continuously till entering the drying pipe.
