Achieving Precision Alignment for Rotary Dryers, Rotary Coolers and Rotary Granulators
Aligning rotary dryer, rotarycooler, or rotarygranulator units is a critical aspect of ensuring their efficient operation and longevity. While the alignment process may seem straightforward after installation, achieving that elusive "sweet spot" - the zero skew position of each roller - is often more challenging than it appears. At Proficient, we specialize in achieving precise alignment, whether it's a new installation or optimizing an existing one.
Proficient Alignment Procedure:
In installations, where rollers are fitted with spherical roller bearings, our process is meticulously designed to ensure flawless alignment. Here are the key steps:- Grind the Rollers and Tyres: To achieve perfect contact and rotation, we grind the rollers and tyres to the required specifications.
- Set Zero Skew: Setting all rollers to a zero skew position is a critical step in achieving optimal alignment.
- Shim for Contact: Precision shimming is performed to ensure perfect contact between rollers and tyres.
- Float the Unit (If Necessary): In some cases, floating the unit may be necessary to fine-tune alignment.
- In New installations the 1st step of grinding is not needed.
Overcoming Alignment Challenges:
The challenge lies in accurately determining the zero skew position for each roller. Traditional methods, such as measuring the position of the bearings, often fall short in achieving the degree of accuracy required. For installations with sleeve bearings, alignment primarily involves floating the rollers, provided the bases are correctly sloped and no shimming is necessary. However, when spherical roller bearings are used, we employ a different approach. Instead of measuring roller positions, we focus on monitoring axial forces on the rollers, providing a more accurate solution.
Steps for Alignment in Existing Installations:
For existing installations, our alignment process begins with correctly positioning the shell in the seals at both the discharge and feed ends. While these initial adjustments may be relatively coarse and not require precise measurements, they play a crucial role in overall alignment. Consideration is also given to optimizing the gear-to-pinion mesh during this process, ensuring that all elements of the system work together seamlessly.
