Spin Flash Dryer for Calcium Chloride (CaCl₂)

Project Overview

We successfully engineered, supplied, and commissioned a Spin Flash Dryer system for the efficient drying of Calcium Chloride (CaCl₂) slurry into free-flowing powder. The system was designed to handle hygroscopic material while ensuring consistent product quality, energy efficiency, and operational reliability.

Scope of Supply

Process design & engineering
Spin Flash Dryer fabrication
Hot air generation system
Cyclone separator & dust collection
Instrumentation & automation support
Erection, commissioning, and performance validatio

Process Description

The CaCl₂ slurry is fed into the Spin Flash Dryer, where it comes into direct contact with high-velocity hot air. A specially designed disintegrator breaks agglomerates instantly, enabling rapid moisture evaporation. Fine, dry particles are conveyed with the air stream, while heavier particles are retained for further drying, ensuring uniform residence time and moisture control.

Key Design Features

Optimized high-shear drying chamber for hygroscopic materials
Special anti-sticking internal surface treatment
Precise temperature and residence time control
Integrated cyclone and bag filter system for maximum powder recovery
Robust design suitable for continuous industrial operation
