HZG series rotary drum dryer
HZG series rotary drum dryer
Detailed description
Works
??
wet material from the dryer is put into one end of the inner cylinder cloth copy turning plate reader, the homogeneous distribution of material in the dryer with the dispersion, and contact and full flow (countercurrent) hot air, speed up the drying mass Heat, spread to the driving force. During the drying process, the material can be regulated to move to the other star discharge valve of the dryer to discharge the product under the action of the tilting plate and the hot air flow.
Adapt to the material
◎ chemical, mining, metallurgy and other industries large particles, dry material than the major, such as: mines, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
◎For the drying of powder and granular materials with special requirements, such as: HP foaming agent, distiller's grains, light calcium carbonate, activated clay, magnetic powder, graphite, and dregs.
◎Requires low-temperature drying, and large batches of continuous drying materials.
Performance characteristics
◎ Rotary dryer has a high degree of mechanization and a large production capacity.
◎ The resistance of the fluid through the cylinder is small and the function consumption is low.
◎ The adaptability to material properties is relatively strong.
◎ Stable operation, low operating cost, and good product drying uniformity.
