HZG manganese slag special dryer
Product Overview: Manganese slag dryer is one of the fastest developing and most widely used drying models in recent years. The manganese slag special
Product details
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.
Performance characteristics
The rotary dryer has a high degree of mechanization and a large production capacity.
The fluid has low resistance and low functional consumption when passing through the cylinder.
Has strong adaptability to material characteristics.
Stable operation, low operating costs, and good uniformity of product drying.
