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 cylinder and
will be distributed uniformly in the drier and contact fully with
the counter current hot air. In this way, the process of heat
conduction is increased.During the period of dry, under the effect
of inclined blades/or angled bafflers and hot air stream,raw
material can be moved to the star section of drier and discharged
from discharging value.
Applications
It is suitable for drying the following raw materials,They are
granules with heavy specific gravity in chemical 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/or Foaming agent, lees,light calcium carbonate, active
white earth, magnetic powder, graphite, lag of medicine and raw
materials that need low temperature and in batch continuously.
Features
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.
