Gypsum Rotary Kiln Introduction

Gypsum rotary kiln is a kind of thermal equipment specialized in calcining gypsum, which is transformed into construction gypsum or anhydrous gypsum through high temperature dehydration. Gypsum in gypsum rotary kiln is mainly used in construction engineering, mold processing, chemical industry, cement conditioning and other industries, which is the core equipment for gypsum deep processing.

The main body of gypsum rotary kiln is an inclined rotating steel cylinder with internal lifting device to enhance the heat exchange, and the working temperature is usually controlled between 150-400℃, which is characterized by continuous production, high thermal efficiency and good product stability.

Gypsum Rotary Kiln Working Principle

The gypsum rotary kiln works on the principle of dewatering phase change of the gypsum raw material by controlled heating. The material enters the slowly rotating inclined cylinder from the end of the kiln and moves towards the kiln head under the action of kiln rotation and gravity. The process goes through three stages: preheating section, calcining section and cooling section.

The raw material enters into the preheater of gypsum rotary kiln and exchanges heat with the hot airflow. After the raw material reaches the cyclone separator, it enters the decomposition furnace for calcination. The calcined product is discharged into the cooling system through the kiln head.

The hot air furnace or gas burner provides heat source, and the exhaust gas is discharged after dust removal. The composition of product phase can be precisely controlled by adjusting the temperature, rotating speed and air volume, and different performance products such as construction gypsum powder or mold gypsum are finally obtained.

Gypsum Rotary Kiln Advantages

Wide material adaptability
High adaptability and inclusiveness to raw materials, no need for fine screening. The temperature gradient is regulated through kiln length zoning to match the needs of gypsum dehydration at various stages, and the raw materials can be directly processed in the production line.

Low processing cost
No coking in the treatment process, simple process flow, energy saving and emission reduction, high thermal conductivity efficiency.

Good safety performance
Adopting indirect heating, safe and stable treatment process with good closure.

Intelligent control
High degree of automation of the production line, through the intelligent control system automatic correction, automatic alarm, DCS system real-time monitoring of temperature, speed, air volume, automatic adjustment of combustion parameters, reducing manual intervention.
