Saw Dust, Palm, Biomass, Stone Rotary Drum Dryer Machine

Supported by the team of experts, we are the leading Exporter, Manufacturer & Supplier of Saw Dust, Palm, Biomass, Stone Rotary Drum Dryer Machine in Zhengzhou, Henan, China. Rotary 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 features
1. It can use chemical gypsum (Free gypsum dehydration, phosphogypsum etc) to fry I -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.
.
Working Principle
Rotating cylinder dryer is a new type continuous dryer which designed on foundation of absorbing foreign technology. The machine is equipped 3 sets inner barrel. Raw material fed from screw import, under the function of rake and hot air flow, raw material will get enough heat and mass transfer after second deflection. Dried product will be collected by cyclone separator of bag filter, damp air will be exhausted by fan.
Main technical parameters

Rotary 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 250-350A 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.
1. 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:
