Industrial Hollow Blade Paddle Drying Machine For Chemical Sludge
KJG Series Hollow Blade Dryer.
Densely lined 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 ugh blades. Unit effect 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 material 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 attachments for 2-4 hollow stirring shaft. 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 ot thermal media have different internal structures to ensure the best heat transfer.
Working Principle
KJG Series New Type Hollow Paddle Dryer for Industrial 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 the machine is generally horizontal type with two or four shafts.

Features
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.
