Zhengzhou Jiutian is currently the most professional and most authoritative enterprise engaged in the research and development of drying equipment in China. The gypsum rotary dryer is a tumble dryer system carefully developed and produced for desulfurized gypsum, gypsum ore powder and other materials. After more than 20 years of drying practice and researches, it has been continuously improved. With its advanced technology, high efficiency, low energy consumption, stable operation, and easy operation and maintenance, safety and environmental protection, praised by users, more than 100 sets of drying equipment are perfectly operating in China and around the world. This type of equipment is widely used in cement, mining, building materials, chemicals, food, metallurgy, chemical, fertilizer production, slag, clay, and other industries. The equipment can be customized according to the type of material, depth of precipitation and user needs to meet the individual needs of each user.
Gypsum tumble dryer is mainly composed of hot blast stove, belt feeder, tumble dryer, belt feeder, induced draft fan, cyclone dust collector, bag filter (or wet dust collector) and operation control system. The equipment adopts the fair current (or countercurrent) drying process. The working principle as following: After entering the drying drum, the wet materials are spitting into the following working areas: First, the material guiding zone. Plaster enters this zone and contacts with high temperature hot air to quickly evaporate moisture. The material is in a large lifting flight angle is transferred to the next working area under the splicing; Second, the copy board area, in which the gypsum is drop and pick up by the lifting flight to form the material curtain state. At this time, the material in full contact with the hot air, and the moisture in the plaster is rapid. The evaporative stripping becomes water vapor, and the water vapor is drawn away immediately by the induced draft fan to achieve the purpose of gypsum drying; the gypsum is dried in this zone to a loose state with moisture below 5-10% (or lower), after heat exchange of the material The required moisture state is reached and the final discharge zone is entered. The third is the discharge zone. The roller does not have a copy board in this zone. The material slides in this zone to the discharge port to complete the entire drying process.
Materials:widely used in cement, mining, building materials, metallurgy, chemical, slag, clay, etc.
Application:Drying gypsum for building materials and industrial applications.

| Note: 1. The internal structure of desulphurization gypsum and gypsum mineral powder drying equipment are completely different, and the specific consulting company is dedicated. 2. The production capacity of the equipment is directly related to the proportion of desulphurized gypsum and gypsum mineral powder to reduce the water content. The proportion of precipitation is large and the production capacity of the equipment is reduced accordingly. | |||||
Fixed-speed quantitative feeder with buffer silo ensures continuous feeding. Non-powered screw disperses large gypsum lumps, preventing blockage and improving evaporation efficiency.
Optimized lifting plates and patented layered drying design form a full-section material curtain, maximizing heat exchange and ensuring uniform drying without over-drying fines or under-drying coarse particles.
Low-oxygen hot air furnace (<5% O₂) delivers stable heat at 700–1100℃. PLC control system monitors temperature, pressure, speed and oxygen concentration for safe, efficient operation.
Dual mechanical sealing ensures airtight operation. Multi-stage dust collection keeps emissions below 30–50 mg/Nm³. Modular design enables easy transport, installation and maintenance.
From solution design to equipment manufacturing and on-site installation and commissioning, Jiutian provide complete one-stop services. The equipment is exported to over 100 countries including UK, Russia, Malaysia, the Philippines, Italy, Israel, Indonesia, Malaysia, Ethiopia, Nigeria, Congo, South Africa, Pakistan, India, Egypt, etc. Looking forward to cooperating with you.
