Handling of Bulk Material Rotary Dryer Machine/Dryer Equipment

Product DescriptionRotary dryer, also called rotating cylinder drying machine, which is mainly used for mineral processing, building materials, metallurgy, chemical, cement industry and other departments drying certain wet degree or the size of material. Rotary dryer is mainly consisting of rotary body, raw material feeding plate, driving and supporting device, etc. Rotary dryer strong adaptability to raw materials can be drying a variety of materials, and the equipment is simple and reliable, so widely used. It is of high efficiency and has the features of reasonable structure, high capacity, low consumption easy operation, etc. It can make final products free from dirt and impurities and reduce the high quality sand loss.
Main Features1. It can use chemical gypsum (Free gypsum dehydration, phosphogypsum etc) to fry β-semi-water gypsum directly.
2. From craft process, guarantee the requests of frying temperature and time which should make precise control in roasting the gypsum.
3. The discharging of work machine is designed rationally, when operation, there is no dust pollution.
4. When interval feeding and discharging, it can be banked fire and shut down furnace. The stove fire can be put into normal production after 3 minutes by again opening furnace.
5. Matched gas stove or fluidized bed furnace is used for supplying heat, the waste heat of tail gas can be used recycling. (Boil water, heat the air.)

InstructionRotary drum dryer Instruction:Rotary drier is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350°C)Rotary drum dryer Structure:Rotary drier machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.Rotary drum dryer working principle:Rotary drier adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
Advantages1. Low outlet air temperature longer service life of dust removal equipment.
2. Sizes of lump materials particles and powders are less than 20mm can be dried.
3. Gear driving is not required and it's directly driven by roller with higher mechanical efficiency.
4. Without the phenomenon of air leakage the sealing difficulty is totally solved and the installation can be finished within a few hours.
5. 50% of area covers has been reduced compared with the single drum dryer and land investment reduced by 50% power consumption reduced by 60%.
6. The self-insulation thermal efficiency of three cylinder dryer can reach above 70% (the self-insulation thermal efficiency of traditional single drum dryer is only 35%) it has remarkable energy saving effect.
7. Final moisture indicators can be regulated easily according to the request.
8. Less than 1% of material moisture can be assured by the three-cylinder dryer which is the preferred product for the dry mixed mortar and slag powder production line.
9. The temperature of discharged material is < 50 ºC which can be directly conveyed into the storage silo needless to cool down in the cooling shed.
Detailed1. High Capacity Rotary Drum Dryer advantages:
reasonable structure, polished manufacture, high capacity, low energy consumption, smooth rotation, easy operation, convenient transportation and so on.2. Rotary Drum Dryer main parts:
cylinder, lifters, driving device, supporting device and sealing ring, feeding device, discharging device, gear, gearbox, electric motor, cyclone dust collector, furnace and etc.3. Rotary Dryer Drum drier heating source:
coal, coal gas, natural gas, LPG gas, wood, and etc.4. Rotary Dryer Drum Drier Mode of flow:
direct flow or counter flow. It is based on the different materials.5.Rotary Dryer Drum Drier principle of operation:
The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.Our ServiceOriental Warranty and service:
