HG Direct Heating Revolving Cylinder Drier
Principle:
When the damp raw material is fed from one terminal. It is turned over through blades that are distributed inside the cylinder and will be distributed uniformly in the drier and contact fully with the countercurrent hot air. In this way, the process of heat conduction is increased. During the period of dry, under the effect of incine blades and hot air stream, raw material can be moved to the star section of drier and discharged from discharged from discharging value.

Features:
High in the etent  of mechanization and strong in production capacity.
The resistance for fluid passing through the cylinder is small. The consumption of power and energy is low.
It has strong adaptability to the properties is cheap. The uniformity of raw material. The operation is stable. The cost of operation is cheap. The uniformity of dried substance is good.

Application:
It is suitable for drying the following raw materials. They are granules with heavy specific gravity in chenmical industry, mine industry, metallurgy industry such as ore, slag, coal, metallic powder, phosphorus fertilizer, ammonia sulfate. Moreover for raw materials that are granules with special requirements, such as HP vesicant, less, light calcium carbonate, active white earth, magnetic powderm, graphite, lag of medicine and raw materials that need low temperature and in batch continuously.
