HG2x12 Meter 20tons per day Big Capacity Rotary Dryer For Coal Drying
Drum drying equipment is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum. Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture in materials film so as to dry materials. Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the blade, and are conveyed, collected and packed.
Product Features
1, It can change operation parameters according to different material property, the dryer cylinder can form full section material
fall which makes the heat exchange more fully;
2, New type feeding and discharging devices completely eradicate the disadvantages of traditional dryer like feeding jams, feeding
discontinuously and unevenly, returning materials, and reduce the load of dust removal system ;
3, Scale plate sealing is used to connect shell and feeding and discharging device , good sealing greatly reduce the shell
internal heat loss, thus directly reducing the fuel consumption;
4, Counter-current drying method obtains higher evaporation intensity; Fair current drying method and indirect drying way are
suitable for drying temperature sensitive material;
5, New burner satisfies the customers’ demand for saving energy and high efficiency. It can choose diesel oil, heavy oil, natural
gas, coal gas etc. to be fuel instead of the only choice for coal as fuel in the past.
Product Working Principle
The heat sources of the dryer is from the combustion train. Because of the tilting device of dryer, when the materials enter into the body from the feeding device, i will flow to the bottom end under the infuence of gravity, as the drier is in an inclined position. This process makes the material well-distributed in the body, then ensure the heat exchange with the heat wind. After repeated cycle with this process,the moisture content will be dried and discharged from the dryer.
Product Application
Rotary Dryers have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulfate, filter cakes, sewage sludge, etc.
