Basic Magnesium Carbonate Flash Dryer
Category: Chemical industry
QUANPIN flash drying disperses basic magnesium carbonate filter cake into a controlled hot-air stream to obtain powder.
Case Details
Working Principle
Tangential air entry creates a rising vortex. A screw feeder introduces wet cake; the rotor breaks agglomerates, while finer particles travel upward for drying and collection.
Structural Design
A compact chamber combines agitation and size reduction. Feed delivery and the lower rotor are selected for the cake’s moisture and stickiness.
Performance Advantages
Rapid dispersion limits thermal exposure and supports uniform powder formation. The short-residence process is intended for cohesive cakes and temperature-sensitive formulations.
Areas of Application
Basic magnesium carbonate, magnesium hydroxide, zinc carbonate and comparable wet filter cakes or pastes.

Material and Process Review
Flash drying brings suitable wet material into contact with a moving heated-air stream. Feed preparation, particle behavior and powder collection affect equipment selection. For a spin flash dryer, review airflow drying performance using representative paste drying or chemical powder drying trials.
Provide feed composition, initial and final moisture, throughput, temperature limits, utilities and cleaning requirements so QUANPIN can define the project operating conditions.
