For many automated fluid control applications, rotary shear
valves coupled to manifolds are a favorable choice for the instrument designer--used for tasks such as solvent selection, flow switching and injecting samples into flowing streams.
Freitas, "Use of a rotary shear
box for testing the shear strength of rock joints," Geotechnique, vol.
 discovered experimentally slip weakening by the colluvium on the sliding surface that was within the range of natural water contents using high-speed rotary shear
tests with maximum shear speed and shear displacement of up to 1.3 m/s and 90 m, respectively (solid lines).
The Crumbier[R] rotary shear
machine, which received a 2016 AE50 Award, operates in tandem with optimized screening to produce feedstocks that have low aspect ratios, uniform cross-sections, and low compressibility--all of which improve flowability.
The three-roll sheet/film system features (3) 8" diameter by 16" diameter wide rolls with linear motion and individual 1 hp AC motors/drives; driven rotary shear
edge trimming; dual unwinds for extrudate lamination/encapsulation utilizing magnetic particle brakes; integral, center driven rewind with automatic gap control and closed loop tension control; air expanding chucks on rewind and upwind shafts; and Allen-Bradley CompactLogix L2 PLC with touchscreen HMI.

Delta Steel Technologies announced it has shipped a 1 inch by 120 inch temper mill cut-to-length line with rotary shear
to a US service centre.
The equipment for Nexans will go to a copper rod mill in Lens, France, and will include a four-blade rotary shear
, Siemens said.
In addition, the latest drive is able to achieve high-bandwidth control loops, allowing it to be used in a wide range of industrial applications, such as printing, cut-to-length, rotary shear
, converting and slitting.
Customers such as Southwire Cable, Coca-Cola and Jaite Packaging have found Rigby's rotary shear
valuable, the company says.
Designs include the B&K Supermill, Rotary Shear
, and Rotary Pierce.
