working principle
After the wet material is invested from one end of the dryer, the looping of the inner tube is evenly distributed and dispersed in the dryer, and the hot air flowing with side (countercurrent) is fully contacting, which accelerates the drying heat and heat transfer. Pass to the driving force. During the drying process, the material can be excreted from another section of the star -shaped material unloading valve to discharge the finished product from the complication plate and thermal flow.
Adapting material
◎ Chemical, mine, metallurgy and other industries are large particles, and large proportion of large materials is dry, such as: mines, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfur.
◎ The drying of powder and granular materials with special requirements, such as: HP foam, grades, light carbonate, active white soil, magnetic powder, graphite, pharmaceutical residue.
◎ Materials are required to dry at low temperature and need to be continuously dry in large quantities.
Performance characteristics
◎ The degree of mechanization of the drum drying equipment is high and the production capacity is large.
◎ The fluid is small through the barrel resistance and low functional consumption.
◎ The adaptability to material characteristics is relatively strong.
◎ The operation is stable, the operating cost is low, and the uniformity of the product is dry.
