GSC Series – Gas Suspension Calciners for Fine-Particle Processing

The GSC Series gas suspension calciners are designed for efficient, high-throughput thermal processing of fine-grained materials, particularly in cement and alumina production. By suspending the feed material in a rising stream of hot gases, these systems ensure uniform heat distribution, intensive heat exchange, and rapid calcination, even for particles with high surface area and moisture content.

Gas suspension calciners are often integrated upstream of rotary kilns to reduce fuel consumption and improve system thermal efficiency. Their multi-stage design allows for precise temperature profiling and residence time control, enabling high-reactivity clinker formation and decomposition of volatile compounds.

Advanced configurations may include preheaters, cyclones, and hot gas generators, allowing seamless integration into modern pyroprocessing lines. Materials such as raw meal, bauxite, kaolin, and industrial by-products can be treated efficiently with minimal emissions and consistent product quality.

Key characteristics:

• Continuous suspension of fine materials for uniform treatment

• Multi-stage temperature profiling

• Low NOₓ and CO emissions with staged combustion

• Compact footprint and modular design

• High throughput with low energy consumption
