Aggregate Sieve Shakers & Sieve Analysis Machines
Match the Shaker to the Required Analysis
An aggregate sieve shaker agitates a stack of test sieves to separate a prepared sample into size fractions. Select the machine for the sample mass, particle range and governing procedure rather than choosing on sieve diameter alone. The machine, sieves, pan and cover together form the working setup.
Round-sieve shakers differ from tray-based aggregate testing screens. Compare the larger screening systems when the prescribed sample cannot be accommodated by a round sieve stack without overloading it.
Compare Tapping and Vibratory Configurations
The WS Tyler RX-29 8in Ro-Tap Sieve Shaker combines horizontal circular movement with vertical tapping. For vibratory equipment, compare the RETSCH AS 200 Control Vibratory Shaker against the operating controls and material requirements of your method.
These agitation arrangements should not be treated as interchangeable for every analysis. Confirm suitability for the material and required procedure, including the available timing, amplitude or interval controls on the exact model. Do not assume a feature listed on one shaker applies throughout the category.
Specify the Complete Sieve Stack
Choose aggregate test sieves with the required frame diameter, openings and frame heights. Full-height and half-height stacks take different amounts of space; allow for the receiving pan, cover and any clamping hardware when checking capacity.
The RX-29 listing identifies sieves as separately purchased and a cover as required for operation. Verify the contents of each selected shaker package before adding sieves or accessories. An adapter should be included in the order only where its compatibility with both machine and sieve diameter is documented.
Check Wet-Sieving Requirements Separately
A dry-sieving machine is not automatically equipped for water use. Where the procedure requires wet sieving, confirm the manufacturer's approval and the necessary lid, seals, water connections, drain and electrical safeguards for that configuration. Do not infer wet capability from the general word “vibratory.”
For rotary-machine choices, use the separate laboratory rotary sifter guide. Keep specialty separation equipment distinct from ultrasonic sieve cleaning baths, which clean equipment rather than replace a sieve analysis machine.
Plan Installation and Routine Care
Check the specified voltage, frequency, mounting and working clearance for the selected unit. The Sound Enclosure for RX-29 and RX-30 Ro-Tap Shakers is a model-specific accessory; confirm space for loading and maintenance before adding it.
Use approved cleaning practices and suitable sieve cleaning brushes. Inspect mesh and frames between runs, and follow the procedure for verifying the sieving endpoint rather than treating a timer setting alone as proof of complete separation.
