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 U.S. to meet CE requirements.
The AutoSiever uses 3,600 sonic energy pulses/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 assuring consistent, repeatable test results for even the most difficult materials. Up to ten profiles can be saved to memory, assuring repeatability for similar materials. Control functions for intensity, ramp/dwell, and total test time to assure fully customizable profiles. 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.
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. Minimal training is required for proper operation.
Sample capacity is a function of particle size and material type. Large particle samples may range up to 20g or about 7cc. Samples with maximum particle sizes of 38µm (No. 400) should be about 10g or 4cc. For precision sieving with electroformed sieves down to 5µm, some samples may be as small as 1g.
When ready for testing the sieve stack is placed atop of the flexible-walled latex fines collector for retaining the fines. A latex diaphragm is placed on top of the sieve stack to seal the air column and confines the sample during testing. A column lock is then locked in place for a complete sieve stack assembly. Once assembled the sieve stack assembly is inserted into the backlit testing chamber and quickly secured in place for testing. Operating time can be set for up to 99.9 minutes. Test times may 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.
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 the user desires to use fewer sieves.
