Product Introduction

Zhengzhou TongDing Machinery and Equipment Co., Ltd. is currently the most professional and authoritative enterprise engaged in researching and developing drying equipment in China. It is the only enterprise in China's drying industry that integrates design, production, and sales, and is dedicated to providing top-notch drying solutions. With nearly 20 years of fast and steady development, Zhengzhou Dingli has gradually become the leader of the Chinese drying equipment industry.

Zhengzhou TongDing has meticulously researched and developed a special drying system and drying machines for desulphurized gypsum, gypsum mineral powder, and other materials. After more than 20 years of drying practice and research, the equipment has been continuously improved. With advanced technology, high efficiency, low energy consumption, stable operation, ease of use and maintenance, as well as safety and environmental protection, the equipment has been praised by users. Currently, over 100 sets of drying equipment are operating perfectly in China and around the world.

The equipment is widely used in industries such as cement, mining, building materials, chemicals, food, metallurgy, chemical production, fertilizer production, slag, clay, and others. Additionally, the equipment can be customized according to the material type, depth of precipitation, and user requirements to meet the unique needs of each customer.

Working Principle

The gypsum tumble dryer is comprised of several components including a 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. This equipment adopts a fair current (or countercurrent) drying process.

The working principle of the equipment is as follows: the wet materials enter the drying drum and are spitted into the following working areas. First, the material guiding zone is where plaster comes into contact with high-temperature hot air to rapidly evaporate moisture. The material is then transferred to the next working area under the splicing while in a large lifting flight angle.

Second, the copy board area is where the gypsum is dropped and picked up by the lifting flight, forming a material curtain state. During this stage, the material comes into full contact with hot air and the moisture in the plaster is quickly evaporated and stripped into water vapor. The induced draft fan then draws away the water vapor, achieving the purpose of gypsum drying. The gypsum is dried in this zone to a loose state with moisture below 5-10% (or lower) after the material undergoes heat exchange and reaches the required moisture state.

Finally, the material enters the discharge zone, which does not have a copy board roller. The material slides in this zone towards the discharge port to complete the entire drying process.

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.
