Principles of Rotary Drying
The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a stationary jacket fitted with either multiple burners or other external heat source.
The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights and the speed of rotation. However, irrespective of the gas and material temperatures the drying (or residence) time may be critical, as this is governed by the rate of diffusion of water from the core to the surface of the material.
For special applications, the rotary cascade design is adapted to provide a shortfall, or ‘Cruciform’, lifter configuration.
Similarly, Rotary Cascade Coolers and Combined Dryer/Coolers are available as required.
Features of the Rotary Drying
Robust construction
Permits use of higher drying temperatures
Relatively long residence time
Drum provides dispersion as material is conveyed along the length
Benefits of Rotary Drying
Combines flexibility with reliability resulting in a long service life. The rotary is also suitable for operation with a wide range of materials & particle sizes and can more readily accommodate ‘upset’ up-stream process conditions
Co-current is suitable for materials with relatively high moistures and provides rapid evaporation without overheating the product. Counter-current has the greatest thermal gradient and helps achieve low product moistures
Reduces equipment size and the associated capital and operating costs
Promotes diffusion drying
Relatively low fan power and low headroom
Enables energy savings

How do rotary cylinders contribute to precise rotational control?
Rotary cylinders play a crucial role in achieving precise rotational control in various applications. Here’s a detailed explanation:
1. Actuation Methods: Rotary cylinders utilize hydraulic or pneumatic actuation methods to generate rotational motion. These actuation methods offer precise control over the application of force, allowing for accurate and controlled rotation.
2. Control Valves: Control valves are used to regulate the fluid flow into and out of the rotary cylinder. By adjusting the valve settings, the rotational speed and direction can be precisely controlled, enabling precise rotational control.
3. Feedback Systems: Some rotary cylinders incorporate feedback systems, such as position sensors or encoders, to provide real-time information about the cylinder’s rotational position. This feedback enables precise control over the rotational movement, allowing for accurate positioning and synchronization with other system components.
4. Stroke Adjustment: Rotary cylinders often have adjustable stroke lengths, which allow for precise control over the range of rotational movement. By adjusting the stroke, the rotational angle can be precisely controlled, enabling precise rotational control for specific applications.
5. Positioning Guides: Rotary cylinders may feature positioning guides, such as grooves or slots, that help guide and stabilize the rotational movement. These guides ensure precise alignment and minimize deviations or wobbling during operation, contributing to precise rotational control.
6. Precision Manufacturing: Rotary cylinders are manufactured with high precision to ensure smooth and accurate rotation. The use of high-quality materials, precision machining, and tight tolerances contribute to precise rotational control, minimizing unwanted variations or errors.
7. Integration with Control Systems: Rotary cylinders can be seamlessly integrated with control systems, allowing for precise control over the rotational motion. They can be programmed and synchronized with other system components, such as sensors, actuators, and PLCs, to achieve precise rotational control in complex automation processes.
These factors combined contribute to the precise rotational control achieved through the utilization of rotary cylinders. It’s important to consult manufacturers’ documentation and guidelines for specific information on the capabilities and limitations of rotary cylinders in achieving precise rotational control.
