High Capacity 20TPH-5000TPH Rotary Drum Dryer for Gypsum with Hot Air Circulation and Dust Removal System

Product Introduction

The gypsum rotary drum dryer is specially designed for drying wet gypsum materials such as desulfurized gypsum, phosphogypsum, natural gypsum, and titanium gypsum. The complete drying system consists of a drying drum, heating system, feeding and discharging units, dust removal system, and transmission components. It can continuously and efficiently dry large quantities of wet gypsum filter cakes and powder materials. After drying, the moisture content of the material meets the required standards and can be directly used for gypsum powder production, building materials, and cement additive manufacturing. The dryer can be equipped with various heat sources, including coal, natural gas, and biomass fuels.

Product Advantages

· Special lifting plates inside the drum effectively disperse and lift the material, ensuring uniform gypsum drying and preventing material agglomeration and sticking to the drum wall.

· Wide production capacity range, supporting 24-hour continuous automatic operation with stable output.

· Hot air circulation and heat exchange structure provide high thermal efficiency, lower energy consumption, and reduced production costs.

· Equipped with self-cleaning and anti-sticking structures, reducing gypsum adhesion inside the drum and minimizing downtime for cleaning.

· Simple temperature control, strong and wear-resistant structure, and convenient maintenance.

· Complete dust removal system reduces dust emissions and meets environmental protection production requirements.

Working Principle

The rotary drum dryer operates with the drum installed at a slight inclination and rotating at a low speed. Wet gypsum is fed into the dryer from the feeding end. Inside the drum, specially designed lifting plates continuously lift and scatter the material, forming a uniform material curtain that fully contacts the hot air, allowing moisture to evaporate efficiently.

The dried material gradually moves toward the discharge end under the force of gravity. Moist air and exhaust gas enter the dust removal system for purification before being discharged. Qualified dried gypsum is continuously discharged from the outlet. The entire drying process is carried out in a sealed negative-pressure environment, ensuring efficient and environmentally friendly operation.
