The free moisture content in phosphogypsum is 20-25%, which seriously affects its application and processing in the fields of environmental protection, chemicals, building materials and other fields. Gypsum drying aims to reduce or remove the free moisture in phosphogypsum to prepare for subsequent calcination and grinding. Provide convenience. Our company's phosphogypsum dryer products have 14 specifications and models according to the cylinder size, ranging from Ø1.2×12m to Ø4.2×42m, the cylinder speed is 2.09-5r/min, and the supporting main motor power is 11-400KW. It can dry 2-46 tons of materials per hour.
Scope of application: Drying of viscous materials such as phosphogypsum, coal slime, washed coal, urban sludge, coal slime, choline chloride, red mud, biological waste residue, etc.
Highlight advantages
1. The dryer has a large processing capacity and is suitable for large-scale production with a single machine production capacity of 1t/h ~ 40t/h.
2. The dryer has low operating cost and the volume heat transfer coefficient is as high as 300-450kcal/m3·℃·h.
3. The rotation speed of the drum can be adjusted steplessly. By adjusting the rotation speed of the drum and the air inlet temperature of the dryer, it can adapt to the properties of different forms of feed materials and meet different product moisture requirements.
4. The equipment operates reliably and has strong overload resistance. The self-aligning tug structure is adopted to reduce wear and power consumption. The special gear wheel structure is adopted to reduce the horizontal thrust caused by the tilting operation of the equipment.
