Sieve Shaker: A Classical Soil Testing Equipment For Soil Particles Separation

Sieves have been used for centuries in many domestic and commercial applications, Soil testing equipment being one of them. A gyratory sieve shaker is used to separate solid particles that are mainly the same size, and match in width and length. A sieve shaker is primarily a corrugated sheet that has sieve openings on the pitch that lies between the ridge and the furrows of the sheet.

As mentioned above the sieve is a not a new apparatus for separation of particles, however the sieve shaker offers more efficiency in separation of particular mixtures of certain particles that are the same in size. The bed of the gyratory sieve shaker or the sieve deck resembles an accordion. The perforations of the sieve are designed to be placed at the side of the pitched areas or as they call it the hills. The valleys or the furrows are not perforated and are designed to match the direction of the material flow so as to allow for passage of material that have elongated shape are of a different size. This material will simply slide off the bed or deck without channelling through the apertures 30.

This mechanism allows for the elongated particles to go through the furrows in the same direction as the material flows, so that there is no collection and they can simply slide in between apertures 30. One can achieve more efficiency by using it at an incline of sieve 10 in the direction that matches furrows 24. When this happens, the particles that are of the same dimensions are swept away by the gyratory or vibratory motion that the gyratory sieve shaker is built with. This gives way to the roll up of the pitch of area 22.

The particles that need to be sieved will easily pass through opening 30 and the remaining particles that are of off size or are elongated and not needed will be discharged into a scrap container without reaching opening 30 but being let out from edge 18 of the screen.

The gyratory sieve shaker is ideal for use as a soil testing equipment as the apparatus allows for separation of soil so as to learn what impurities may be present. It also allows for separation of particles that are of no use so as to add efficiency to agricultural processes.

The gyratory sieve shaker is a device that is mounted on a carrier that works with gyratory or vibratory motions.
