Optimized kiln structure, refractory selection, and process control support consistent residence time and temperature stability—key to reliable calcined kaolin/metakaolin performance.
The burner system can be configured for different fuel choices based on local availability and compliance needs (e.g., natural gas, diesel, or pulverized coal—subject to project design and regulations).
From process design to layout guidance, installation/commissioning support, and training—our solution is built for customers who need an integrated production line, not just a single kiln.
Sealed feeding/conveying plus dust collection (cyclone + pulse bag filter) helps reduce dust leakage and supports cleaner operation. Safety guards, emergency stops, and compliant electrical/control configurations can be applied per project scope.

Kaolin is fed from hopper/feeder to the next stage. If your feed contains oversized lumps, a size-control step (crusher/screen) can be included to protect downstream equipment and improve kiln stability.
For higher-moisture kaolin, a rotary dryer or pre-drying section reduces moisture, helping stabilize the kiln thermal balance and reduce fuel consumption.
A sealed and metered feeding system controls the feed rate, reduces air leakage, and supports stable kiln operation and dust control.
Kaolin travels through the rotating kiln with controlled residence time and temperature profile to achieve the required phase transformation and product performance.
The hot calcined product is cooled by a rotary cooler or other cooling solution. Heat utilization options can be considered to improve overall energy efficiency.
Dust-laden gas is treated by a dust collection system (commonly cyclone + pulse bag filter). Additional measures can be integrated according to local standards and customer requirements.
The cooled product is conveyed to silo/bulk storage or packing system for shipment.
