Model 026

The sieves are designed for sieving the sand base when determining the granulometric composition of the fineness and average grain size in land laboratories of foundries, central factory laboratories and laboratories of research institutes.
Sieving of the sand base is carried out on a rotary-shaking action installation providing 300 ± 5 eccentric revolutions and 180 ± 10 strikes of the striker per minute or on a vibrating action installation that vibrates the sieves with an vibration amplitude of 0.1-1.0 mm and a frequency of 50 vibrations / from.
