Rotary Dryer System Alignment
Precision Engineering Survey
A DATscan 2.0 is a cold drum (performed when a rotary dryer or unit is shut down) engineering survey that measures system alignment. A DATscan 2.0 gives you baseline measurements to inform your maintenance and repair decisions for your rotary equipment. Whether you’re preparing for a plant shutdown or in the middle of one, a DATscan 2.0 is a great tool to help guide your next steps concerning your rotary unit. This precision engineering survey is checked three ways and boasts an accuracy of +/-0.040”.
Types of Measurements
Information included in the DATscan 2.0:
- System Slope
- Base Slope
- Support Roller / Trunnion Slope
- Tire / Roller Angle
- Brief Visual Inspection

Why Schedule a DATscan 2.0?
Understanding a Float vs. a DATscan 2.0
An alignment situates the support rollers so that shell flexing is minimized. The beginning of understanding alignment is to know where the support rollers / trunnions are holding the equipment in relation to a straight line. Alignment is best utilized as a preventative maintenance measure. A DATscan 2.0 provides the data necessary to perform an alignment on your rotary unit.
Quick View of a Float vs. DATscan™2.0
- Alignment such as slope
- Can determine roller coordinate system
- Can get base slope information
- Determine base settling if any
- Determine diameters of tires and rollers
- Compare coordinates to base centers
- Referred to as skew, thrust Neutralization, or balancing a rotary unit
- Makes sure the rollers give a balanced uphill thrust
