The origin of heat of gypsum dryer comes from the burning device. The machine adopts downstream method to heat. Therefore, raw materials enter into the cylinder from the feeding box and feed slide. After that, they were sent to the behind of drum by the spiral copy board. Because of the oblique of drum, the materials is flow to the end by the action of gravity and turning. On the other hand, material is copied repeatedly and taken to the top, then, they were spread down continually so that the material form a uniform screen screens in the barrel and achieve heat exchange fully with the hot air of barrel. Material will be dried by repeated scattering during which moisture content is evaporated gradually. The device is suitable for drying gypsum, fly ash and other materials
Gypsum dryer is mainly constituted by front and rear wheel cylinder device. Inlet and out equipment, rigging, gear cover and other components. Gypsum dryer doesn’t include these ancillary equipments like combustion chamber, feeding the discharging equipment, dust collection equipment
2.The special internal structure of rotary dryer ensure the wet materials that will not block and stick the dryer. 3.Rotary dryer can resist the high temperature so that it can dry the material quickly and have a large capacity. We can offer the optimal briquetting and drying solutions for processing industrial wastes
The thermal current is divided to downstream and countercurrent, and the heating method is divided to direct heating and indirect heating. 4. According to different material characteristic, it chooses different inner structure to meet drying requirement of the materials. 5. Effective prevention of the material against sticking on the wall; an ideal system for drying of material with high moisture content and viscosity
Then the material moves to the other end of the internal layer and gets into the middle layer, where it gets counterflow dried. Here, the material not only fully absorbs the heat emitted from the internal cylinder, but also from the middle cylinder. The material gets fully dried in the rectangular shoveling plate, thereby the drying process is finished
Thermocouples are installed in feeding and discharging units to control temperature. Point 3-nspection Examination all the parts according to the drawing after processing Spraying primer, rust preventing paint, and heat resistance paint. 4. Professional logistics service ensuring safety and timely delivery of products all over the world through ocean, airline, road and railway
We always offering lifelong services and provide spare parts for a long term, and repairing main parts under right using for free in two years. We sincerely welcome friends from all over the world to visit our company and cooperate with us on the basis of long-term mutual benefits. 3) After-sales service: Dispatch engineer to the site to guide installation, debugging and training operators
Materials enter the rotary drum from the higher side, and hot air enters the barrel from the lower side. ( There is honeycomb board design at the two sides of rotary drum, biomass material will not burn during drying process. 3. F eature s of sawdust rotary dryer  Highly mechanized, huge production capacity and continuous operation production ability
ROTARY DRYER Rotary dryer is used for such as calcite, sand minerals before grinding process for dehumidifying. Moisture is an unwanted factor during the grinding process, it may reduce the grinding capacity or become it impossible in some cases. Rotary dryers, depending on the inclination and the rotational speed of the plaster and cement kiln furnace as in progress allows the material moves through into an oven, at same time the heated air passing in the drying furnace process. Depending on required capacity and humidity of all sizes and dimensions for dryers may be designed
