Powerscreen to showcase hybrid screen, digital technology at CONEXPO-CON/AGG 2020

Powerscreen will showcase digital technology and equipment at CONEXPO-CON/AGG 2020. Three machines will be on display: the Powerscreen Premiertrak 600XL jaw crusher, the brand new Powerscreen Chieftain 1700X Hybrid screen and a Powerscreen CT75R tracked radial stockpiling conveyor.

Chieftain 1700X Hybrid

The brand new Chieftain 1700X Hybrid features a highly aggressive screenbox with a patented 2/4 bearing drive system and improved screening angle. Growing on the Powerscreen legacy of high performance four bearing screen boxes, the new screen on the Chieftain 1700X aims to outperform similar sized screenboxes on the market.

The 16ft x 5ft screenbox maintains the screenbox size and mesh of the current Chieftain 1700, but with increased screening force and an increased screening angle.

A number of other plant changes have been implemented, such as changing the way the fines conveyor is suspended for easier transport as well as self-tensioning side conveyor sealing rubber and feed-boot improvements for quicker setup and lower running speed for reduced fuel usage without compromising power.

The 3 Deck machine is available with a hydraulically folding extended auxiliary conveyor, complete with a transfer conveyor that allows 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 2 Deck screen, allowing maximum versatility with a single plant.  

The Powerscreen Hybrid option gives customers an alternative energy source, providing a choice on which fuel to use depending on cost, location and availability. 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. 

Premiertrak 600XL

The Preimertrak 600XL jaw crusher has proven to be a popular choice in large quarrying operations due to the strength and durability of its XL feeder. In particular, this machine excels in applications where hard rock may be present and where large tonnages required.

The diesel-hydraulic and diesel-electric variants of the Premiertrak 600 jaw crusher have been designed to deliver maximum production and performance whilst increasing uptime and lowering running costs. The high capacity jaw is fed by an elongated vibrating grizzly feeder with variable speed control and an independent pre-screen to maximize removal of fine material, extending the wear life of jaw plates within the crusher chamber. The bypass chute is also fitted with wear-resistant liners as standard and incorporates an adjustable five-position deflector plate to divert material to either the product or side conveyors.

The machine control system incorporates a modern interface with intuitive graphics and high resolution display for ease of operation. This is further enhanced with the automatic start/stop functionality, diagnostic capability and straightforward machine adjustments. The speed of jaw crusher on the Premiertrak 600 can be varied to suit the application and therefore optimize performance. In addition to this, the hydraulic system has been designed and configured to increase uptime and fuel efficiency. 

The Premiertrak 600E electric variant is also equipped with an over-size genset, sufficient to run another plant and additionally can be powered from a mains source which substantially decreases the running costs and environmental impact.

CT75R 

The mobility and flexibility of tracked radial conveyors reduces/eliminates the use of a wheel loader on site as well as significantly reducing fuel, labour and maintenance costs. 

This machine has the versatility to cater for a large number of material handling applications, complete with a range of additional options to meet the individual needs of each customer. Options include: overband magnet, dust suppression solutions and radio remote to start/stop the feeder and raise/lower the discharge conveyor. The CT75R can be easily transported using a low loader or packed in to a container for shipping.
