Product introduction
The drum dryer is generally used for drying limestone, clay, coal powder and mixed materials in cement plant. It is also applied in metallurgy, mining, electricity, chemical industry and other sectors for drying ore concentrate, tailings and grain with a certain humidity and granularity. It can be set up as an independent unit as well as a complete system which includes dust collector, feeder, conveyor and other necessary machines.
Product Advantage
Low energy consumption: Reasonable operating parameter, both coal consumption and electricity consumption are reduced by 10-15%.
High thermal efficiency: Concurrent flow drying, materials and hot air enter into the dryer from the same side, low exit temperature and high thermal efficiency.
Large processing capacity, small floor area, easy to install and maintain.
Compact and reasonable structure design, stable and convenient operation.
Main Structure
Drum Body: The major component of the drum dryer exist inside the drum body. Wet materials can directly or indirectly get the heat from the heat carrier when moving forwards.
Lifting Plate: The lifting plate is used for changing the motion state of the material inside to increase the heat transfer efficiency in the drum dryer. Thus the drying process will be faster and the heat efficiency is increased.
Dust Collector: It is used for collecting dust produced in the material drying process, which can decrease the dust pollution in the operation.
Working Principle
Heat source of the dryer comes from combustion device, which uses concurrent flow heating method. The materials enter into the barrel from feed box, then being pushed forward by spiral lifting board. Because of the slant installation of the dryer, the materials flow to the tailing end under the action of gravity and rotation. On the other hand, the materials are repeatedly lifted and spread by the lifting board, thus forming even material curtain inside the barrel. The materials fully exchange heat with the hot air in the cylinder. Since the material is repeatedly lifted and spread, the contained moisture is gradually reduced to achieve the drying purpose.
