Rotary Barrel Vacuum Drying Machine Natural Gas Heating High Efficiency


HYG-P Rotary   Conductive style drying machine (Rotary dryer, rotating dryer ,Rotary drying


machine , Rotary drying equipment  ) 




Mostly the machine is used in per burning of rigid magnet oxygen Pulverized fodder, it is also suitable for the cement, metallurgy and chemical industry, it is made up of main kiln body and supporting Drive set cooling pipe and supporting drive set, fuel system, electricity control secondary air set, exhaust dust and warm-up kiln body etc. The machine has function like: give an alarm for over temperature, give an alarm for over loading, auto control for working temperature,oxygen atmosphere is adjustable in the kiln etc.


The principle of work

When the damp raw material is fed from one material, it is turned over through blades that are distributed inside the cylider and wil be distrubuted 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 discharging value.




It is suitable for drying the following raw materials,They are granules with heavy specific gravity in chemical industry, mine indystry,metallurgy industry such as ore, slag, coal,metallic powder,phosphorus fertilizer,ammonia sulfate. Moreover for raw materials that are granules with special requiremnets, 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.

1. The motorization level of the barrel is high, and the production capacity is high;

2. The resistance that the material passes through the barrel is less, and the power consumption is low.

3. Application capability to different characters of materials is high.

4. The operation is stable, the operation fee is low, and the uniformity of product drying is good.
