3. Drying Technologies for Mineral Raw Materials
Rotary drums and fluidized bed dryers add quality to your process
Hengyang Industry drum and fluidized bed dryers make
processes more productive Today, Hengyang Industry
dryers are used successfully in almost all industrial sectors.
Particularly in the mineral processing industry but also in
the chemical and fertilizer industry and in recycling
operations, the rotary drum dryers and fluidized bed dryers
prove their extraordinary abilities. Hengyang Industry
drying systems are extremely adaptable. Their design
features and the large number of available options permit
the design of productive processes.

4. Hengyang Rotary Dryer
Single-shell, double-shell and triple-shell drums
Hengyang rotary drum dryers are used, particularly in the minerals industry, for drying free flowing but also sticky and
abrasive wet materials. Their main features are high throughput rates and the ability to process solid materials with widely
differing granulometric properties. The drum dryers are available in single-shell, double-shell and triple-shell versions.
Single Shell Rotary Dryer
For coarse-grained materials, clay products, broken glass,
etc.
Double Shell Rotary Dryer
For drying of fine-grained minerals, silica sand and ore.
Triple Shell Rotary Dryer
For drying materials which require long dwell times. For
easily free-flowing products with fine to medium grain sizes.
Combined processes
Hengyang has extended and perfected the use of Rotary Drum
dryers. The result of this work is a range of designs for new
combined processes in a single system which are therefore
very effective and economical.
A technical highlight is the double-shell drum dryer system
which dries and cools the sand in a single step. The feeding
part of the wet product, referred to as the “bypassing product”,
directly into the outer drum. There it is mixed with the dry and
warm product from the inner drum which dries the wet
bypassing product and cools down the dry product by
evaporative cooling.
Drying & Cooling Sand
Double-shell drum for combined drying and evaporative
cooling of sand. Well proven in the manufacturing of ready
mixed dry products like mortar and plaster.
Drying and Cooling
Double-shell drum with air-cooling path, for grain sizes up to
32 mm (sand, crushed limestone, etc.)
Drying and Crushing
With grinder. Dries and crushes lumpy materials such as
filter cakes. This improves or enables the drying of lumpy
products to produce fine grained dry materials.
5. Drying and Screen
With screening unit. This system dries and screens many
types of materials with reasonably good separation
(aluminium
scrap, shredded recycling products, ...). There is thus a
reduced need for separate downstream screening steps.
Granulation and Coating
This system produces granules from powders and
cakes, such as of fertilizers, lime, bentonite and clay.
It can also be used for coating applications (urea,
potash granules).
Drying and Cleaning
With cleaning zone. This system replaces separate
washing steps especially for lime stone aggregates or
increases the amount of good material from dry
separation.
Drying Of Waste
Municipal waste or paper rejects can be dried quickly
and economically in drum dryers.
Cooling
Two different systems of indirect rotary drum coolers for
hot and very hot bulk materials (titanium dioxide, slag,
hydroxides, gypsum) with heat recovery from the hot
products.
