HZG serise rotary drum dryer

The HZG-type rotary dryer has a cylindrical drum structure with a slightly inclined main body, and its rotational speed can be adjusted within a certain range. Wet materials are fed into the drum through a feeder. Under the flipping action of the lifting plates uniformly distributed on the inner cylinder, the materials are evenly distributed and dispersed inside the dryer. They come into full contact with the hot air passing through the drum (in parallel or counterflow), thereby enhancing heat and mass transfer to achieve the drying purpose. The equipment can adopt various types of lifting plates to adapt to the drying requirements of different raw materials.

Working principle

After being fed into one end of the dryer, the wet material is evenly distributed and dispersed in the dryer by flipping the plate reader evenly distributed in the inner cylinder, and fully contacts with the hot air flowing in parallel (counter current), accelerating the heat transfer during drying and transmitting it to the driving force. During the drying process, the material can be controlled to move to the star shaped discharge valve in another section of the dryer to discharge the finished product under the action of the inclined plate and hot air flow.

Application areas

Suitable for large particles and high-specific-gravity materials that require drying in chemical engineering, mining, metallurgy and other industries, such as ores, blast furnace slag, coal, metal powders, phosphate fertilizers, and ammonium sulfate. 

Materials with special drying requirements for powders and granular materials, such as HP foaming agents, distillation residues, light calcium carbonate, active bleaching earth, magnetic powder, graphite, and medicinal dregs. 

Materials that require low-temperature drying and continuous large-scale drying.     



Performance characteristics

The rotary drum dryer has a large production capacity. 

The heating fluid encounters low resistance and consumes less energy when passing through the cylinder. 

It can meet the requirements of different material properties and has strong adaptability. 

It operates stably, has low operating costs, and provides good drying uniformity.
