1. Rotary dryer machine
The Rotary Dryer is widely used in the field of building materials,
metallurgical, chemical industry, cement and so on. It can dry
slag, coal powder, mining powder, clay, sand, limestone and so on.
It is made into rotary body, lifting blade, driving device,
supporting device etc. The Dryer has advantages of reasonable
structure, high efficiency, low energy consumption and convenient
2. Working Theory of Rotary dryer
Rotary dryers consist of a horizontally inclined rotating cylinder.
Material is fed at one end and discharged at the other end. In
direct-type rotary dryers, hot gases move through the cylinder in
direct contact with the material, either with or against the
direction of its flow. The cylinder is equipped with flights, which
lift the material and shower it down through the hot gas stream.
3. The Rotary dryers has been optimized a lot , which possesses the
following characteristics :
1. The internal adopts assembled structure which has improved the
accuracy of the equipment and it is easy to transport and install.
2. According to the characteristics of different fertilizers ,we
have arranged the second granulation zone reasonably so as to
improve the granulation effect .
3. Adopts assembled hoist board so as to exchange heat fully and
lower the energy consumption .
4. Temperature induction monitor ,uniform vibration and airproof
setting , which improve performance and productivity efficiently .
5. The assorted combustion furnace is a type of energy-efficient
and has the characteristics of smaller area ,easy regulation and
equipped with greenhouse .
