Audited Supplier Dongding Gypsum Rotary Dryer is manufactured to dry FGD gypsum, phosphogypsum, titanium gypsum, fluorogypsum, gypsum powder, gypsum plaster and other materials.
Dongding desulfurization (phosphogypsum) gypsum drying equipment process is advanced.
The gypsum rotary dryer is of high thermal efficiency, low energy consumption, small occupation area, energy conservation and environmental protection.
The complete set of gypsum rotary dryer equipment has various specifications, the annual processing capacity is 50000-200000 tons according to the needs of users.
Gypsum Rotary Dryer Working Principle
Firstly, gypsum slurry is crushed by the crushing machine, transported to the screw conveyor by the belt conveyor,
then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor,
the left material will go into the cyclone dust collector, where the dust will be collected, with the function of the induced draft fan, the left material will be discharged through the conveyor.
Dongding Gypsum Dryer Advantages
1. The chemical gypsum (desulfurized gypsum, phosphogypsum, etc.) can be directly fried into β - hemihydrate gypsum powder;
2. Precise control of the drying time and temperature are ensured;
3. Reasonable design of the air outlet, no dust pollution;
4.Multiple heating source choices.Tailored solutions for each customer.
