The discharged stones from the primary sieves contain some grains. This mixed fraction is sent to the secondary sieve by a pneumatic transfer system, using a built-in fan. Stones are concentrated and discharged.
Heavy-duty construction, permanent lubrication and easy access to sieves for cleaning or replacement result in very low maintenance.
The Satake Destoner is a compact unit and requires less installation space. The vibratory drive eliminates the need for any pulleys, belts, eccentric bearings, etc. and contributes to the improved sanitation in plants.
