Product Description
Rotary dryer is a common industrial equipment widely used in the
drying process of various materials, particularly suitable for
materials requiring large-scale, continuous drying. Its principle
involves the continuous agitation of the rotating cylinder and the
transfer of heated gas to evaporate moisture from the material
surface and achieve the desired humidity standards. In industrial
applications, rotary dryers are commonly used for drying materials
such as metal powders, iron ore pellets, slag, quartz sand, blue
carbon, brown coal, fly ash, quartz sand, and clay.
Product Advantages
1. High-efficiency drying performance
The rotary dryer continuously flips the material through the
rotation of the cylinder, allowing it to fully contact the hot
airflow and thereby accelerating the evaporation process. Compared
to traditional drying methods, the rotary dryer can achieve higher
drying efficiency in a shorter time, making it suitable for
processing large quantities of material.
2. Energy-saving and environmentally friendly
Rotary dryers enable efficient use of energy. By optimising the
heat exchange system and implementing reasonable temperature
control design, rotary dryers not only reduce energy waste but also
lower emissions of harmful gases such as carbon dioxide. When
processing wet materials, heating methods such as hot air or steam
are used to minimise energy consumption, aligning with modern
environmental protection and sustainable development requirements.
3. Wide Applicability
Rotary dryers have excellent applicability and can process various
granular, powdery, blocky, or slurry materials. Whether it is metal
powder, slag, brown coal, blue carbon, or materials such as quartz
sand and clay, rotary dryers can be adjusted according to the
properties of different materials to ensure their effectiveness in
various application areas.
4. High Durability
Rotary dryers feature robust equipment structures constructed from
high-quality wear-resistant and high-temperature-resistant
materials, enabling them to withstand high temperatures, pressures,
and wear during prolonged operation. This results in a long service
life and stable performance even in harsh working environments.
Product Application
1.Metal Powders:
Rotary dryers are highly effective in removing moisture from metal
powders during production, preventing moisture from adversely
affecting the powder's flowability, adhesion, and final
performance. Especially in the drying of high-performance metal
powders such as aluminium powder and copper powder, rotary dryers
ensure powder quality with their uniform drying and high-efficiency
advantages, meeting the requirements of subsequent processing.
2. Iron ore pellets:
In the smelting process of iron ore, rotary dryers are commonly
used to dry iron ore pellets. Pellets must be dried to an
appropriate moisture content at high temperatures to proceed to the
next smelting stage. Rotary dryers ensure uniform drying of pellets
by controlling temperature and humidity, preventing low smelting
efficiency or increased production costs due to excessive moisture.
3. Slag:
Slag, as a by-product of smelting, must undergo drying treatment
when it needs to be reused or disposed of. Rotary dryers
effectively remove moisture from slag, ensuring its stability
during storage, transportation, and subsequent use. They also play
a significant role in industries such as cement production and
concrete production, ensuring the drying quality of slag and
thereby improving production efficiency.
4. Quartz sand:
Quartz sand is an important raw material in industries such as
construction materials, glass, and chemicals. Rotary dryers can
process large quantities of quartz sand, achieving the desired
drying level quickly through uniform heating and agitation, thereby
avoiding moisture-related quality issues. After drying, quartz sand
exhibits good flowability and storage stability, meeting the drying
requirements for materials in industrial production.
