Graphite hollow paddle dryer for new energy industry

Description of Hollow Paddle Dryer:

KJG Hollow Blade Dryer can indirectly heat or cool the materials in paste, granules, powders and slurry materials. It can also complete the unit process of drying, cooling, heating, sterilization, reaction and low temperature combustion. The special heat-transfer stirring blade wedge type in the equipment has high heat-transfer efficiency and its heat-transfer surface has self-cleaning function.

KJG Hollow Blade Dryer is a kind of low-speed stirring dryer which has a stirring blade set inside the machine, making the wet materials have a full contact with heat carrier and hot surfaces under the stirring of the blade, to achieve the purpose of drying. Its structure is generally horizontal, dual-axis or four-axis. This dryer is divided into conduction type.

Features of hollow Paddle Dryer:

1. Blade paddle dryer is low energy-consumption: due to the indirect heating, there is not a lot of air carrying away the heat; the outer wall of the dryer set the insulation layer. for slurry material, it takes only 1.2kg water vapor to evaporate 1kg water.
2. System of blade dryer is low cost; the heat transfer area is large in unit effective volume, which makes shorter the processing time and the smaller device size, greatly reducing its covering area and building space.
It can handle wide ranges of materials: Using different heat medium, it can not only deal with heat-sensitive materials, but also materials requiring high temperature treatment. Common media are: steam, heat transfer oil, hot water and cooling water.
3. It supports both continuous operation and intermittent operation; it can be applied in many fields.
Environmental friendly: it does not use carry air and carries very little dust material. Material solvent evaporation is little so it is easy to handle. for materials which may cause pollution or requiring solvent recovery, closed circulation can be applied.
4. Low operating costs: little abrasion, low maintenance cost.
Stable operation: due to the special compression - expansion stirring of wedge-shaped blade, material particles have sufficient contact with the heat transfer surface. In the axial zone, materials have low temperature, low humidity and small mixing gradient so as to ensure the stability of the process.
