Gypsum calcination equipment is usually processed with two ways: one step and two step. One step method is to complete the drying and calcining process of gypsum with one equipment. It is suitable for small scale desulphurized gypsum with water content less than 10%. Simple process, small heat loss, less investment cost. The two-step method is to complete the drying and calcining process of gypsum with two equipment separately. The two-step method is generally suitable for large-scale production lines with high water content.
Uniform heating, dynamic calcination, no raw and overburning phenomenon, can be continuous automatic production..
Optimized structure configuration, equipment running stably, can be equipped with complete anti-corrosion, insulation measures according to the requirements.
Circulation heating and drying system, greatly saving energy, equipped with efficient dust removal device, green environmental protection.
The equipment process is simple, the production capacity is large, the equipment operation is safe and stable.
Gypsum is first shoved into the feeder, and then evenly sent to the belt conveyor by the feeder, and then into the dryer through the material guide tube, heat generated by the combustion of fuel in the heat conduction oil furnace under the action of heat transfer of heat conduction oil into the main engine and gypsum heat exchange contact, gypsum in the drying roller uniform copy plate flip. It is evenly dispersed and fully in contact with hot air to accelerate the heat transfer, mass transfer and evaporation of moisture in the drying of desulfurized gypsum. The gypsum dryer produced by our company is a sealed structure, which can reduce heat loss and improve thermal efficiency. The dried gypsum is discharged through a discharge hopper and transported to a designated location for storage. The upper part of the discharge hopper is the dust collecting process. After being treated by the dust collecting system, it can achieve the purpose of environmental protection.
