Hollow Blade Dryer Drying Machine for Gypsum/Phosphogypsum Powder Drying
Dual counter-rotating shafts with unique intermeshing hollow wedge-shaped paddles produce intimate mixing, optimize heat transfer, and provide a self-cleaning feature. A large heat transfer area to volume ratio is achieved by the use of hollow paddles and a jacketed vessel, through which the heating medium flows. The result is an efficient, compact machine with less space requirements and lower installation cost.
The Hollow Paddle Dryer has a metal wall which separates the process mass from the heat source (steam or hot oil). High thermal efficiency is obtained because the heat from the thermal medium goes directly into the process mass. As the material comes into contact with the heated through and agitators, the process mass is heated via conduction. With an insulated dryer, very little heat is lost. To evaporate 1kg of water only requires about 1.2kg of steam for slurry materials. Exhaust gas is minimal and at a low temperature. Therefore, the volume of non-condensable gas from the dryer, which might require treatment, is minimal.
The dryer is an indirect heat transfer device which utilizes a high degree of mechanical agitation to enhance contact with the product being dried. Evaporation rates per square foot of heat transfer surface are maximized through self-cleaning paddles and the mixing effect. Movement of the process material between the slanting surfaces of the revolving wedge-shaped paddles generates shearing forces, which clean the paddle surfaces and maximize conductivity. Counter rotating shafts move the material away from the walls, cleaning the walls by means of the tab on each paddle. This results in higher heat transfer rates than disc or single shaft designs.
The wedge-shaped paddles, and the intermeshing of the dual agitators, create a localized mixing effect around the paddle. This allows more individual particles in the bed to be exposed directly to the heat transfer surface, thereby increasing the heat transfer rate, allowing the use of smaller equipment.

Applications
Petrochemical industry: polyolefin powder, polycarbonate resin, high and low-density polyethylene, linear low-density polyethylene, polyacetal granules, nylon 6, nylon 66, nylon 12, acetate, polyphenylene sulfide, propylene base resin, polypropylene, engineering plastics, polyvinyl chloride, polyvinyl alcohol, polystyrene, polyester, polyoxymethylene, styrene-acrylonitrile copolymerization, ethylene-propylene copolymerization.
Environmental protection industry: sludge, electroplating sewage sludge, boiler soot, sugar factory waste residue, pharmaceutical factory waste residue, MSG factory waste residue, coal ash.
Feed industry: soy sauce residue, bone-based feed, distiller's grains, food scraps, apple pomace, orange peel, soybean meal, chicken bone feed, fish meal, feed additives, bio-sludge.
Food industry: starch, cocoa beans, corn kernels, salt, modified starch, medicines.
Chemical industry: soda ash, NPK compound fertilizer, kaolin, bentonite, white carbon black, carbon black, phosphogypsum, calcium sulfate, calcium nitrate, magnesium carbonate, sodium cyanide, oxidized sodium fluoride, aluminum hydroxide, barium sulfate, calcium carbonate, molecular sieves, dyes, saponins.
1) Low energy consumption: As a result of indirect heating, no much air take away the heating, the outer wall has insulation layer, the heat efficiency can be up to 90%. For slurry, evaporating 1kg of water just need 1.2kg vapor.
2) cheap investment: it has huge effective heat transfer surface area per unit, reduce treatment time, let the machine size become small, so It greatly reduces the construction area and building space.
3) wide range of materials handling: can use different types of media, not only can treat heat-sensitive materials, but also handle high-temperature materials. Common medias are: water vapor, thermal oil, hot water, cooling water and so on.
4) flexible operation method: Can be continuous operation or intermittent operation, can be applied in many fields.
5) Low environmental pollution: don't use air to dry material, dust material entrainment is rare. Small solvent evaporation, easy to treat. For contaminated materials or solvent recovery conditions, closed-loop can be used.
6) Cheap operating costs: Low-speed mixing and reasonable structure, Low wear, low maintenance costs. For normal operation, just only 1 person / day.
7) Stable operation: Due to the special compression-expansion stirring of the wedge blades, the material particle contact with the heat transfer surface enough, it ensure the processing is stable.
