Chieftain 2200 Greywacke

Chieftain 2200 - Machine photo

BACKGROUND

The key information we wanted to gain from the test site was how a Powerscreen Chieftain 2200 compared to a Powerscreen Chieftain 2100X (which the customer already owned). In the customers original setup they were using their Chieftain 2100X to screen out a 14mm product, a 10mm product, a 6mm product and a waste dust product. To create these products within the required specification they often needed secondary screening. The Powerscreen Chieftain 2200 was brought into site and setup to the customers preference for testing.

At this site in Ballynahinch, a Powerscreen Chieftain 2200 screened ‘Greywacke’ rock.

SETUP

A Jaw was being used to Primary crush the material at 125mm CSS. This jaw was feeding a 1300 Maxtrak Cone set at 30mm CSS, feeding a screen with a re-circulation of material entering a 1000 Maxtrak at 18mm CSS.
