Drum dryer series
HZG series rotary drum dryer
Detailed description
summary:
After the wet material is put into the dryer from one end, the material is evenly distributed and dispersed in the dryer under the overturning of the plate copying device uniformly distributed in the inner cylinder, and fully contacts with the parallel flow (countercurrent) hot air, which speeds up the drying flow and mass transfer driving force. In the process of drying, the material can move to the star discharge valve at the other end of the dryer to discharge the finished product under the action of inclined plate and hot air flow.
Application:
Drying of large particles and materials with large specific gravity in chemical, mining and metallurgical industries, such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer and ammonium sulfate.
Drying of powdery and granular materials with special requirements, such as HP foaming agent, distiller's grains residue, light calcium carbonate, activated clay, magnetic powder, graphite and drug residue.
Materials requiring low temperature drying and continuous drying in large quantities.
characteristic:
The rotary dryer has high mechanization and large production capacity.
The resistance of fluid passing through the cylinder is small and the function consumption is low.
It has strong adaptability to material characteristics.
Stable operation, low cost and good drying uniformity.
