W.S. Tyler developed the Ro-Tap Test Sieve Shaker in the early 1900s. Until that time, sieving was primarily performed by hand. Today, the Ro-Tap Test Sieve Shaker is used to measure particle-size distribution. The design intent was to replicate and mechanize sieving hand motions. The Ro-Tap Test Sieve Shaker, with its rotating movement and tapping energy, provides for the most consistent, repeatable sieving analysis results. The Ro-Tap is the required test sieve shaker in many industrial specifications. Currently, there are no industry standards governing the calibration of the unit itself. W.S. Tyler recommends the product users develop their own quality control program.
