Continuous disc dryer is a new type of conductive drying equipment, which has the advantages of continuous operation, closed operation, high evaporation intensity, reasonable humidity gradient distribution, low power consumption, small footprint and so on. At the same time, its configuration is simple, does not need to be equipped with spray drying must be configured cyclone dust collector, does not use hot air as the heating medium, therefore, there will be no product loss due to bad separation of hot air and dust with tail gas entrained.
The disc continuous dryer is composed of a drying disc, a rake arm, a number of rake blades installed on the rake arm, roller, a spindle, a transmission device, a shell, etc., and a heating medium is passed into the hollow drying disc. The drying tray is divided into two kinds of large plate and small plate, horizontal layer arrangement in the dryer, the drying tray is stationary, the material on the large plate in the rake leaf driven from the outside to the inside of the movement, from the inside edge of the large plate into the inside edge of the small plate, the material on the small plate from the inside to the outside movement, from the outside edge of the small plate into the large plate, the material on the drying plate surface by the rake leaf transport, flip, in the Archimedes spiral track movement, In the process of movement is heated by the drying disc, heat and mass transfer to complete the drying operation, according to the output of the dried material, properties, initial and final water content, determine the drying disc layer number (drying area). The disc dryer works vertically, the wet material is added by the top feeding port, and discharged by the bottom of the dryer after passing through each layer of drying pan. The whole drying process is closed and the water steam released from the material is directly discharged into the atmosphere by the exhaust pipe on the top of the dryer. The main component of the tail gas is water steam, and there is no entailing by the dried product.

(1) Organic chemical products
Disc dryer is widely used in the drying of cotton seed, alcohol, liquor, beer, chemical products, medicine and other industries discharging waste residue. Other products include protein feed, bio-potassium fertilizer, aureomycin for feed, mycelium, bran, wine grains, grains, seeds, herbicides, cellulose, feed, calcium hydrogen phosphate, polytetrafluoroethylene resin, fumaric acid, anthraquinone, nitroanthraquinone, p-aminophenol Organic chemical raw materials and intermediates such as melamine, cyanuric acid, p-aminobenzenesulfonic acid, nitroaniline, dipentaerythritol, chlorinated paraffin, calcium formate, triethylenediamine, sodium benzenesulfonic acid, m-phthalic acid, sodium dimethyl pentasulfonic acid, thiourea dyes.
(2) Inorganic chemical products
Light calcium carbonate, active calcium carbonate, nano-scale ultra-fine calcium carbonate, magnesium carbonate, potassium carbonate, kaolin, bentonite, aluminum hydroxide, white gray black, strontium carbonate, barium carbonate, potassium carbonate, barium sulfate, potassium sulfate, microsphere catalyst, magnesium hydroxide, copper sulfate, nickel sulfate, cryolite, iron oxide red, lithium hydroxide, nickel hydroxide, calcium phosphate, sulfur, etc
20,000 tons of light calcium carbonate and active calcium carbonate drying system application disc continuous dryer
The thermal efficiency is higher than that of the rotary tube dryer, and the annual coal saving is 200 tons, and the economic effect is remarkable.
