Energy Saving 8 tph Rotary Drum Dryer for sand, cement, gypsum
1. Structure of rotary drier
Drier also named as Drying Machine and Rotary Drier.Drier is mainly
consist of rotary body, raw material feeding plate, driving and
supporting device, etc
2. Application of rotary dryer
Rotary drier is used to dry slag, clay, limestone, It is mainly
used for cement, chemical, metallurgical, building materials
industries.
3. Working principle of rotary dryer
When rotary Dryer is operating, it shall be in direct contact with
heated gas. The dryer consists of a large rotating cylindrical
tube. In order to convey the material through the underside of
dryer, the dryer should be slanted slightly to ensure that the
discharge end is lower than the end of material feed .
Working Principle of Rotary Dryer: Material shall be dried to enter
the dryer. When the dryer is rotating, a series of internal fins
will lift the material by lining the inner wall of the dryer. When
the material reaches certain height to roll the fins back, it will
be fell back to the bottom of the dryer, then passing through the
hot gas stream as it falls. This gas stream can either move toward
the discharge end from the feed end (known as co-current flow), or
toward the feed end from the discharge end (known as
counter-current flow). The gas stream can be composed of a mixture
of air and combustion gases from a burner, and in which case the
dryer is known as a direct heated dryer. Alternatively, the gas
stream may be made up of air or another (sometimes inert) gas that
is preheated. When the gas stream is preheated by some means where
burner combustion gases are not permitted to enter the dryer, the
dryer shall be called an indirect-heated type. Indirect heated
dryers are commonly used when product contamination becomes a
concern.
