Sieve Shakers

The Gilson Wet/Dry vibratory sieve shaker is an economical electric sieve vibrator and is helpful for fast separations of wet or dry materials using one or two 8in (203mm) diameter full-height ASTM test sieves. Vibration energy is transferred directly to the sieve frames, promoting the passage of finer particles from wet or dry material. This unit works with particles ranging in size from 1 inch to No. 200 (25mm-75µm). The vibrator frame is constructed of powder-coated steel with an integral vibrating unit mounted on the top of the unit and is designed for use with the notched plastic bucket to collect fines. It operates on a 115V, 60Hz 3-wire cord and plug. For operation with 230V, order the TR-502 Step-Up/Step-Down Transformer. For wet samples, use WT-7 Spray Fitting, WT-5 Spray Bottle, or other wet-sieving accessories. For dry sieving applications, SSA-20 Notched Bucket to catch fine material or use an extended-rim sieve pan with a single sieve.

• Inexpensive yet effective unit for fast separations of wet or dry materials
• Durable mounting on a steel frame keeps the unit secure
• Ideal for quick scalping of oversize materials from bulk samples
• Notched bucket sold separately

3" / 76 mm Sieve Shaker is designed for small samples of chemicals, minerals, pharmaceuticals, powdered metals, cosmetics, abrasives, ores, foods, and other fine powders. Useful range is 75 µm - 4.75 mm (No. 200 to No. 4 sieve sizes) with woven wire sieves, but many materials may be sized smaller using electroformed sieves.

High frequency, 3600 vpm, electromagnetic vibratory action with 0-100% amplitude control is ideal for fine particle separations. Inline solenoid-actuated tapping action may be used during vibration (60 taps/min.) to speed dry separations. Also use the tap separately for tap-settling and bulk density tests. During dry sieving, the tapping action redistributes the sample on the sieves, and breaks static blinding, helping to clear undersize particles rapidly.

Model SS-3 includes a platform assembly for up to seven full-height. 3" / 76 mm metal sieves and pan or 14 acrylic sieves and pan. The unique sieve clamping mechanism makes insertion and removal of the sieve stack simple and convenient, yet holds the sieves snugly during operation. The captive knobs on the clamping mechanism allow it to be raised with a quick twist, releasing the sieves. The mechanism remains at this height until the knobs are twisted in the opposite direction clamping the sieves in place. The Performer III’s compact size, small footprint, and quiet operation make it an extremely desirable instrument for dry powder sample separations.

Model SS-3 features include an attractive, but rugged coated steel case, on/off controls for vibration and a manual/timed mode switch. A digital timer showing time set and time remaining, the numbered vibration control knob, and simple, efficient electromagnetic vibratory action enable the Performer III to give reliable, repeatable results. Optional stackable acrylic 3" / 76 mm see-through cylinder is helpful for observing sample action while leveling platform or for setting vibration.

8" SS-15 Sieve Tester is a budget, portable, 8" / 203mm sieve shaker designed to outperform other comparably priced equipment. The 1/4-hp unit is widely accepted by state transportation departments for highway materials testing. Back and forth lateral motion is combined with up and down and tilting motions to cause test material to travel in an orbit on the sieve surfaces. This forced travel assures full use of sieve mesh area without precise leveling of the tester. The SS-15 is recommended primarily for No. 4 to No. 200 size range, but may be used with larger material sizes when specifications for sieve loading and sample quantities permit. The Tester holds 6 full-height sieves and pan or 13 half-height sieves and pan. Clamp bar with attached cover secures sieves. The 15-minute timer has an adjustable knob-stop for improved repeatability, and a "hold" feature for continuous running. Freestanding operation is normal, but may be mounted via holes provided in bottom end flanges.

Designed to be used in coarse testing applications, the affordable RX-812 Coarse Sieve Shaker has unique capability of using both 8" diameter and 12" diameter test sieves, simply by using the quick-change adapters provided. The RX-812 has a quet operation and utilizes an effective "action" that gives consistent, accurate results.

• Designed for use with 8" and 12" diameter Test Sieves.
• For analysis of particles US #100 (150 µm) and larger
• Oscillating movement only
• Supplied with adapter for 8" and 12" Test Sieves
• Oscillations per Minute: 280 (60Hz); 231 (50Hz)

The Industry standard in test shakers, W.S. TYLER® RO-TAP® RX has a unique two dimentional operation: a horizontal, circular motion and a vertical, topping motion. This special action allows material particles to stratify and "seek" critical openings in the test media. The result is the most accurate and consistent particle analysis testing.

12"/8" Sieve Shakers provide sharpest repeatable separations in minimum time over the broadest possible range of particle sizes, shapes, and densities.

The W.S. Tyler® Rotay Sifter sifts 8 or 12 inch (200 or 300mm) sieves in a dust free enclosure.

• Accurate Results
• Safe and Effiicient

W.S. TYLER® RO-TAP® RX-94 Test Sieve Shakers utilizes the same traditional design as the RX-29 and RX-30 models. In addition, the unit features a cavity that allows for two "stacks" of 8" diameter test sieves. This allows for twice the processing capacity in nominally the same time required to complete one test.

The W.S. TYLER® RO-TAP® Electronic Test Sieve Shaker operates with 8" or 12" diameter Test Sieves and offers precise sieving results. The RX-29-E compact (8" Test Sieves) unit requires minimal space on a laboratory countertop and designed for light to medium testing applications. The RX-30-E (12" Test Sieves) model is a floor unit. Controls can be remotely mounted for convenient operation.
