HZG series rotary drum dryer

Overview:
    After the wet material is put into one end of the dryer, the material is evenly distributed and dispersed in the dryer, and the hot air is fully contacted with the co-current (countercurrent) to speed up the drying and flow, Mass transfer driving force. In the drying process, the material in a copy board with a tilt and the role of hot air, can be controlled to move to the other end of the dryer discharge valve star finished.

application:
● Chemical, mining, metallurgical and other industries large particles, than the major material drying, such as: ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
● For the special requirements of powder, granular material drying, such as: HP foaming agent, distiller's grains, light calcium carbonate, activated clay, magnetic powder, graphite, dregs.
● Low-temperature drying is required, and large quantities of continuous drying materials are required.

Features:
● Drum dryer high degree of mechanization, production capacity.
● Fluid resistance through the cylinder is small, low-power consumption.
● The adaptability of material properties is relatively strong.
● stable operation, low operating costs, good uniformity of the product dry.
