Simple screening machine with a single sieve with one product outlet and one waste outlet. Controlled by a motor-vibrator with adjustable eccentric masses for a max power of 85 Watts, mounted on vibration dampers and a closed profile counterframe to keep the damping action constant even when the inclination of the shaker varies.
The closed profile floor support frame includes the product entry, which is thus fixed, regardless of the inclination of the shaker. The sieve is made of wood and Formica with an upper gasket in nytal or stainless steel wire cloth, cleaning balls and support net for them in electro-welded and galvanized steel. The sieve is blocked by tightening lateral screws. An internal shutter, adjustable from the outside by touch, allows for regulation of the flow rate and distribution of the product to be processed.
