GilSonic AutoSiever Sonic Sifter

GilSonic AutoSiever Sonic Sifter offers the most precise and dependable separations for particle sizing of fine granular materials and dry powders ranging from No.20 (850µm) to 5µm. The AutoSiever uses sonic sieving action with two-way (horizontal/vertical) tapping to achieve the most accurate and reliable particle separation of fine dry powders and granular materials. The AutoSiever is designed and manufactured in the USA to meet CE requirements.

The AutoSiever uses 3,600 sonic energy pulses per min to oscillate the air column enclosed within the sieve stack. This agitation continuously excites and reorients particles to the mesh surface. Programmable tapping clears the sieves and prevents clumping of materials. This program feature is built into each unit and can be programmed for horizontal and vertical, vertical only, or turned off completely.

The easy-to-use control panel allows fully customizable testing profiles with control functions for intensity, ramp/dwell, and total test time to ensure consistent test results for many different material types. Up to ten profiles can be saved to memory, assuring repeatability for similar materials.

Test times vary depending on material type and particle size. Five minutes is the typical testing length, but some samples may be complete in as little as thirty seconds. Operating time can be set for up to 99 Minutes, 59 seconds ±1 second. Sieving intensity (amplitude) is selected with a proportional power controller. The ramping function automatically increases power at a programmed rate for optimum separation of difficult materials.

Sample volume and maximum capacity are based on particle size, density, and other material characteristics. Sample volumes with larger particles, such as No.20 (850µm), can be as large as 20g. Samples with a particle size below No.400 (38µm) should not exceed 10g. For precision sieving with electroformed sieves as small as 5µm, samples may be as small as 1g.

Fines are retained in a flexible walled latex fines collector. A latex diaphragm on top of the sieve stack seals the air column and confines the sample during testing. The complete stack assembly is held together with a column lock, inserted into the backlit testing chamber, and quickly secured into place for testing. Minimal training is required for proper operation.

The cabinet is powder-coated steel with a sliding acrylic door. The enclosed design operation reduces dust to help confine and control the airborne respirable particles in the breathing zone of personnel.

The AutoSiever accommodates seven 3in woven-wire cloth ASTM E11 Acrylic Frame Test Sieves or three 3in ASTM E161 Precision Electroformed Nickel Mesh Sieves in the fixed-height stack assembly. Order GAA-88 Acrylic Spacers if fewer sieves are desired.
