Product Details

Working Principle
Powder or granular materials are loaded into the double-cone vessel via vacuum feeding or manually. As the vessel rotates continuously, the materials undergo complex tumbling and impact motions within the container. This movement ensures uniform mixing while drying under vacuum conditions, preventing oxidation or damage to sensitive materials.

Key Features
Suitable for heat-sensitive, easily oxidized, or toxic materials.

Preserves the integrity of crystalline substances.

Efficient moisture removal with vacuum drying.

Continuous rotation ensures uniform mixing of materials.

Energy-saving, easy to operate, low labor intensity, and high operational efficiency.
