Kaolin Rotary Kiln Introduction

Kaolin rotary kiln (China clay rotary kiln) is a professional production equipment for calcining kaolin. Mainly through high-temperature treatment, kaolin removes crystalline water and undergoes phase change, transforming into calcined kaolin with higher activity and stability. Kaolin rotary kiln is also known as kaolin calcining furnace, which can also be used for calcining clay, kaolin, bauxite, magnesium oxide, zinc oxide and other materials. It is widely used as a functional filler or reinforcing material in the fields of papermaking, coating, ceramics, rubber and catalyst.

Kaolin Rotary Kiln Working Principle

The working principle of kaolin rotary kiln is that through the tilted rotating cylinder, the kaolin raw material enters the cylinder from the end of the kiln through the preheater and moves slowly towards the discharge end of the kiln head, while rolling forward along the cylinder direction in the circumferential direction. In this process, the material passes through drying, preheating, calcining (1000-1500℃) and cooling stages in turn, removing crystallized water and undergoing phase change under the action of high temperature, transforming into calcined kaolin clinker, which is then discharged from the kiln head, i.e. the lower end. The final product is cooled and discharged, which can be used in paper making, ceramics and other high-end fields, characterized by high whiteness and good activity.

Kaolin Rotary Kiln Advantages

Kaolin rotary kiln has the advantages of high production efficiency and stable product quality, so it is widely used in the production of kaolin and other mineral materials. In the process of producing kaolin, kaolin rotary kiln can reduce the emission of waste gas and waste water, so as to achieve the purpose of reducing environmental pollution. Kaolin rotary kiln can also be used to process kaolin raw materials containing water and organic matter, improving the utilization rate of raw materials and the benefits of resource recycling.

• Efficient and uniform calcination: kaolin rotary kiln medium temperature calcination of ultrafine kaolin process technology represents the development direction of ultrafine kaolin calcination technology, the calcination technology has low energy consumption, high yield, product dehydration, decarburization, whitening performance is stable. The rotary kiln adopts rotating cylinder design, so that the kaolin is constantly turning during the movement, ensuring uniform heat, avoiding local over-firing or under-firing, and improving the stability of product quality.
• Strong adaptability and high output: Kaolin rotary kiln can handle kaolin raw materials with different particle size and moisture content, with fine grading and high precision. Automation control realizes 24-hour continuous operation and high production capacity, which is suitable for industrialized large-scale processing.
• Excellent product performance: small crushing limit particle size, large crushing ratio and processing capacity, low energy consumption per unit of product, low abrasion consumption, high efficiency, widely used in high-end fields such as papermaking, coating, rubber, catalyst and so on.
• Energy saving and environmental protection: adopting counter-current heat exchange design, the high temperature flue gas preheats the cold material to improve the thermal efficiency; cooperating with the tail gas waste heat recovery and dust removal system, it reduces the energy consumption and pollution emission.
• Convenient maintenance: modular structure design, key components (such as refractory lining, transmission device) are durable and easy to overhaul, low operating costs.
