The new Powerscreen Chieftain 1700X Hybrid screen

Mobile crushing and screening equipment company Powerscreen has launched the new Chieftain 1700X Hybrid screen.

The Northern Irish manufacturer says the screen features a highly aggressive screenbox with a patented 2/4 bearing drive system and improved screening angle.

It adds that the 16ft x 5ft (4.87m x 1.5m) screenbox maintains the screenbox size and mesh of the current Chieftain 1700, but its greater screening force and an increased screening angle both combine to give a superior screening performance.

After listening to its customers, the company said it had made a number of other plant changes to the 1700X. These include changing the way the fines conveyor is suspended for easier transport, self-tensioning side conveyor sealing rubber and feed-boot improvements for quicker setup, and lower running speed for reduced fuel usage without compromising power.

A three-deck machine is available with a hydraulically folding extended auxiliary conveyor, complete with a transfer conveyor that is designed to allow easy re-circulation with the entire range of Powerscreen crushing machines. Alternatively, with a quick valve change the conveyor can run in reverse, effectively turning the machine into a two-deck screen, allowing maximum versatility with a single plant.

The Powerscreen Hybrid option gives customers an alternative energy source, letting them choose which fuel to use depending on cost, location and availability. The company says this option will be of special interest for customers in areas where electricity is more cost effective than diesel fuel and on sites where electricity is the preferred energy source. Powerscreen Hybrid machines are fitted with an additional electric/hydraulic drive system which can be connected to an external electricity supply once the machine has been setup onsite.
