Skako Screens solve ‘sticky’ problems
Skako Vibration have developed a range of heavy-duty scalping screens to handle ‘sticky’ and difficult-to-handle materials which would otherwise cause blinding and product adherence problems on conventional units.
These scalping screens have already proved themselves in a variety of applications, including: handling moist sand and gravel with sticky deposits; handling ‘all in’ limestone on a waste- recovery plant reclaiming slag and coal; and as ‘protection’ screens to remove unwanted oversized materials.
The critical components of the screens are the special forged tines which perform the scalping operation. With a special sculptured tapering design, they are forged from silicon manganese spring steel, delivering high stress resistance under dynamic loading, together with high-levels of wear resistance.
Available in 35mm standard and 45mm heavy-duty nominal diameters, and having a scalping length of 600mm, they can be arranged with nominal scalping apertures of between 40-150mm while handling feed materials with top sizes in excess of 200mm.
The screen itself is of heavy-duty ‘Huck’ bolted stress-free construction, and depending on the size, is driven by either twin unbalanced motors or a geared exciter. The resultant linear displacement allows high-capacity efficient scalping to be achieved.
Standard or customized designs can be offered in widths of 600mm, 800mm, 1,000mm, 1,200mm or 1600mm, with between two and five 600mm long scalping sections, resulting in screening lengths of 1,200 to 3,000mm. The units can be either open or totally enclosed.
