Desulfurization gypsum dryer

[Structural component]

Intermittent drum Gypsum powder is mainly constituted by front and rear wheel, cylinder device, inlet and outlet equipment, rigging (driving device), gear cover and other components. Gypsum dryer doesn’t include these accessory equipments, like combustion chamber, feeding and discharging equipment, dust collector equipment.

[Working principle]

The origin 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 drum behind by the spiral copy board. Because of the oblique of drum. The materials 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 forms uniform screen in the barrel and achieve heat exchange fully with the hot air in the barrel. Material will be dried by repeated scattering during in which moisture content is evaporated gradually. The device is suitable for drying gypsum, Fly ash and other materials.

[Main feature]

1. It has strong anti-overload, large capacity, less fuel consumption, low cost.
2. Hot air and the wet material enter into the dryer from the same side. Adopting downstream for drying; materials can use high temperature air to obtain a high evaporation, dryer temperature is low in the outlet and it has high thermal efficiency.
3. According to material nature, it can change operating parameters so that the material can form a stable and full cut fabric curtain to achieve mass and heat exchange more fully in the dryer drum.
4. New feeding and discharging devices eliminate the phenomenon of feeding stoppage, discontinuous, ununiform and returning materials of roller dryer and reduce the load of the dust system.
5. Dryer achieves “zero thrust” which greatly reduces the wear of gear wheel and guarantee cylinder to operate smoothly and reliability.
6. Dryer uses“self-aligning roller-type device” that make the under roller and the rolling ring to keep linear touch forever, thereby reducing wear and power loss greatly.
7. According to user’s requirement, it can control the moisture content of products.
