Introduction of Kaolin Dryer
The mined kaolin or clay because of longtime deep buried in the ground, containing a certain degree of internal moisture. They rely on a drying step to reduce shipping costs, improve handling characteristics, prepare the kaolin for downstream processing, and ensure clay materials meet their specific performance standards.The kaolin dryer is specially designed by our company to dry the wet kaolin or clay from the moisture about 25% to 8%. It is widely used in building materials, metallurgy, chemical, and cement industries,etc. This system is mainly suitable for materials with high water content, fine granularity and large viscosity.
Kaolin Dryer Applicable Raw Material
Kaolin (white clay, china clay)
Clay
Bentonite clay
Ball clay
Fire clay
Fuller's earth (Input moisture: 40-50%, final Moisture: 10%)
Advantages of Kaolin Dryer
01
Large Capacity, Low Cost
Large processing capacity with low fuel consumption and low drying cost.
02
High-Temperature Resistance
High-temperature-resistant design allows high-temperature hot air to dry materials quickly.
03
Automated Control
Computer automatic control enables remote operation, with drying temperature and time configured to suit the kaolin or clay.
04
Self-Aligning Support
A self-aligning tugboat structure keeps the tug and rolling ring well matched, greatly reducing wear and power consumption.
05
Multiple Heat Sources
Coal, biomass pellets, natural gas, diesel, electricity and other heat sources are available.
06
Low Investment & Fast ROI
Low equipment investment and operating cost with quick return on investment.
Working Principle of Kaolin Dryer
Firstly, wet material is crushed by the crushing machine, then transported to the rotary drum dryer by the belt conveyor. Because of the inclination of drum dryer, material with hot air moves to the end of dryer body, during which process wet material gets fully contact with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The left materials mixed with dust continue go into the cyclone dust collector and the bag dust collector in sequence, where the dust will be collected. Lastly, with the function of induced draft fan, the left material will discharged through the conveyor.
