3D DIGITAL SIEVE SHAKER The 3D Digital Sieve Shaker is ideal for laboratory or on site use. It is robust, compact and sufficiently lightweight to be portable. A digital display makes the setting of the microprocessor controlled functions very straightforward. The 3D Digital is powered by an electromagnetic drive which has no rotating parts to wear making it maintenance free and extremely quiet in operation. The vibratory action produced by the power unit moves the sample over the sieve in a unique way producing faster more efficient sieving, while the rapid vertical movements also help to keep the apertures from blinding. The 3D Digital's digital controller is used to set both the process time and the amplitude setting while a further control enables the vibration to run continuously or intermittently. Intermittent vibration improves performance and helps to clear apertures that may have become blocked. The controller will also set the duration of both the on and off times of the vibration. Essa's 3D Digital shakers are fitted with a new and totally unique clamping device. It ensures sieves are held firmly without over-tightening and allows them to be quickly removed and replaced. Non-metallic springs and anti-vibration mountings are fitted to isolate vibrations from work surfaces and reduce noise levels. ALSO AVAILABLE: SST450 SUSPENDED SIEVE SHAKER An electro-mechanical shaker for suspended mounting and carrying up to two off 450mm diameter standard test sieves. OST450 SIEVE SHAKER For dry sieving with 450mm square or round sieves.
