KJG series hollow blade drying machine for sludge
Product Description
Description of sludge dryer:
Densely line with wedge-shaped hollow shaft hollow blades , heat medium through the hollow axial flow through blades .unit effective volume of a very large area of heat transfer ,heat medium temperature from-40 to 320 ℃ can be water vapor ,may also be liquid-type: Such as water, oil and so on .indirect conduction heating, the air does not carry away the heat, the heat are used to heat materials. Only through the device body heat loss to the environment, heat insulation layer.
Wedge-shaped blades with self-cleaning heat transfer surfaces. Wedge-shaped surface particles and scrubbing effect relative movement, to wash away the wedge surface material attachments, so in operation have maintained a clean heat transfer surfaces .blade dryer for the w-type shell, the shell of the general arrangements for 2-4 hollow stirring shafts. Shell with a sealed cover with the cover to prevent dust leakage and collection of materials, solvent vapor materials.
Set out and exit pull a block, to ensure a high degree of material level, so that heat transfer surface is covered with fully materials. Heat medium through the rotary joint, passing through the shell jacket and the hollow stirring shaft, hollow shaft stirring according to the type of thermal media have different internal structures to ensure the best heat transfer.

Principle of sludge dryer:
KJG hollow blade drying machine for sludge is a kind of conduction heating and low rotating speed-stirring type drier. There is jacket on the body of drier, hollow oar blade on the hollow shaft, filling heating medium in them, wet material is stirred by oar blade and carries on heat exchange with shaft and oar blade. The structure of machine is generally horizontal type with two or four shafts.

The structure of machine is generally horizontal type with two or four shafts.
Features of sludge dryer:
1. Blade dryer energy consumption is low: as indirect heating, the air does not carry away a lot of heat insulation of dryer wall has, on the slurry material, evaporation of 1kg of water vapor only 1.22kg of steam
2. Blade dryer system costs low: within the effective volume of units have a large heat transfer surface, the reduced processing time, equipment size becomes smaller. Would greatly reduce the building area and building space.
3. Dealing with a wide range of materials: using a different hot medium, able to deal with heat-sensitive materials can be heat-treated materials handing. Commonly used media are: water, steam, oil, hot water, cooling water. Continuous operation can also be intermittent operation can be applied in many fields.
4. Environmental pollution: do not carry air, dust entrainment few materials. Solvent evaporation of material is very small, easy to handle. To have contaminated materials or be recycled solvent conditions, can be used closed circuit.
5. Low operating cost: the equipment normal operation, 1-2persons/day. Low speed and reasonable structure. Wear a small, very low maintenance costs.
6. Operation stability: as the wedge-shaped blades of special compression-expansion of stirring, so that material particles sufficient surface contact with the heat transfer in the axial zone, the material temperature, humidity, mixed density gradient is very small, thus ensuring the process stability.
Application of sludge dryer:
KJG series vacuum paddle drying machine has been successfully used in food, chemical, petrochemical, dye, industrial sludge and other fields. Heating, cooling, mixing features make it to complete the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), response and sterilization. Mixing blades at the same time the heat transfer surface, the effective volume per unit area of heat transfer increases, reducing the processing time. Heat transfer surfaces in wedge-shaped blades with self-cleaning function. Compression – expansion mixing features make the material mixed uniformly. Material along the axis into a “plug flow” movement, in the axial zone, the material temperature, humidity, mixing a very small degree of gradient.
Adaptation materials:
Petrochemical industry: polyolefin powder , Polycarbonate resin , high and low density polyethylene , linear low density polyethylene, polyacetal particles, nylon 6 , nylon 66 , nylon 12 , cellulose acetate , polyphenylene sulfide, propylene base resin , engineering plastics , polyvinyl chloride , polyvinyl chloride, polyvinyl alcohol, polystyrene, polypropylene , polyester , polyoxymethylene ,sludge – acrylonitrile , ethylene propylene copolymer.
Environmental protection industry: PTA sludge ,electroplating sludge into the water , boiler ash, pharmaceutical waste, sugar residue, glutamate factory water ,coal ash .
Feed industry: soy sauce reside, bone-based feed, grains , food scraps ,apple ,orange peel, soybean meal, chicken feed , fish additives , bio-sludge.
Food industry: starch, cocoa beans, corn kernels, salt, modified starch, pharmaceuticals.
Chemical industry: soda ash ,NPK fertilizer, kaolin, betonies, white carbon black, carbon black, phosphorus gypsum, oxidation of sodium fluoride, calcium nitrate, magnesium carbonate, sodium cyanide, aluminum hydroxide, barium sulfate, sulfate acid, carbonate, dyes, molecular sieve, spooning.
