Chinese Dryer Manufacture Efficient Paddle Dryer For Sludge Treatment In Chemical Plants
Paddle dryer is an indirect drying equipment with hollow paddles/blades installed usually in a horizontal hollow axle rotating in a vessel. the wet feed is dried when the rotating paddles stir the materials and resulting in a close contact with the heated paddles and vessel shells. The dryer has a high heating transfer surface and high heat efficiency due to no heat loss in exhaust gas(only heat loss is radiation via heavily insulated dryer vessel, which is very trivial). The paddles are self-cleaning due to relative motion between the wet feed and the wedge-shaped paddles. Paddle dryer can work in batches or continuously, in vacuum, protective atmosphere or pressure conditions according to drying requirements and nature of wet feeds. The heating medium can be thermal oil or hot water with pressure from 0.1 MPa to 0.8 MPa, Steam with pressure up to 1.5 MPa. Working temperature: 40 C to 300 C. Evaporation capacity: 8Kg to 60Kg/m2.h
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.
