HZG Roating Cylinder Dier
Description
After the damp raw material is put into the dryer from on end,it is turned over through strring-up rake inside the cylinder and distributed uniform in the dryer and contacted with countercurrent hot air fully.It speeds up heat and mass conducting of dry.During the oeriod of dry,raw material is effcted by stirring-up rake with gradient and hot air,it can be moved and passed through the dry region and to star valve and then
discharge the finished product.
Application
Used in chemical, miners, metallurgical and other industries big particles, large proportion of dry material. Such as ore, blast furnace slag, coal, metal powder, ammonium phosphate sulfur.
Have special requirements to powder, granule materials dry. Such as: G P foaming agent, sprinkle the slot slag, light calcium carbonate, activated clay, magnetic powder, graphite, liquid.
Request dry at low temperature, and be large quantities of continuous dry material.
