Working Principle of XSG Rotary Flash Dryer

1. Material Feeding

   Undried materials including wet granules, powder and pastes are delivered into the dryer through the feeding port.
2. Crushing and Dispersion

   High-speed rotating crushing components such as propellers, blades and hammers break materials into fine particles, expanding specific surface area and accelerating drying efficiency.
3. Hot Air Drying

   Hot air is injected into the drying chamber with adjustable temperature based on material properties and finished product standards. Moisture and solvent are rapidly evaporated through sufficient contact between hot air and crushed materials.
4. Classification and Collection

   Dried materials are carried to classifying equipment, generally cyclone separators. Qualified fine powder is separated and discharged. Oversized unqualified particles return to the drying zone for reprocessing until meeting requirements.
5. Waste Gas Treatment

   Exhaust gas containing vapor and volatile substances passes through dust removal facilities like bag filters to eliminate solid particles before atmospheric discharge.
6. Control System

   It regulates drying temperature, air volume and other parameters to maintain stable operation and consistent product quality.

   Technical Improvements

   Rotary flash dryer is one of our core products. Our equipment has been widely used nationwide across pigment, dyestuff, petroleum, building material, food, feed, pesticide and related intermediate industries. We have successfully solved numerous tough problems regarding feeding, drying and separation via scientific analysis and repeated tests. Customized drying solutions are available for materials of varied properties to meet customer requirements.

   1. Multiple feeding devices optional for steady continuous feeding without bridging.
   2. Special cooling structure installed at the dryer bottom to prevent material deterioration under high temperature.
   3. Exclusive pneumatic sealing and bearing cooling design extends service life of transmission components.
   4. Optimized air distribution unit reduces operational resistance and balances internal airflow velocity.
   5. Classifying ring and swirling blades equipped to regulate finished fineness and residual moisture content.
   6. High circumferential air speed and short material residence time avoid wall adhesion and deterioration of heat-sensitive materials.
