Sifter (Sieve Shaker) 3D VGH II
A universal vibratory sieve shaker with three dimensional motion, for foundry sand, powders and other materials, with wet sieving possible. The VGH II drives a full nest on a timed run, so every analysis sees the same agitation.

A universal vibratory sieve shaker for the laboratory, suited to foundry sand, powders and other materials where particle size decides quality. The VGH II drives a full nest in three dimensional motion, so material is presented to every aperture rather than tracking the same path, which is what makes the cut even and the result repeatable.
A timed run. The run is set on the timer, so the agitation stays a constant from one analysis to the next rather than a matter of judgement. The shake is part of the method: too little and fines are still held up in the nest, too much and the sand is worked rather than graded.
Intensity, time and tapping are set, not guessed. The vibration intensity is variable and the run is set on the timer, so a given sand is graded the same way each time. Auto end tapping knocks grains clear of the cloth, and the nest is held by a quick clamp.
Dry and wet sieving. Foundry sand is normally graded dry, on a dried and split sample. Wet sieving is possible where fines cling to the coarser grains and a dry shake does not release them.
