Powering ahead in mobile crushing

POWERSCREEN has recently added two new crushers to their extensive product range. The mobile crushing and screening equipment provider launched the Powerscreen 1150 Maxtrak cone crusher and Powerscreen Premiertrak 600 earlier this year.

The Premiertrak 600 is described as a high performance primary jaw crushing plant machine. Specificed for quarrying, demolition and mining applications that require high production capabilities, especially in hard rock, the machine was launched at the Nordic Open Event held in Stockholm at the end of May.

In advance of the Premiertrak 600’s release, a handful of Powerscreen customers were given the opportunity to test the machine and provide feedback on its usability. Ed O’Donohue from Roadstone, who operated the machine at the company’s crushing and screening sites in Ireland, said, “We ran the Premiertrak 600E electric jaw crusher at a limestone quarry in Co. Meath and also used it to crush demolition concrete at a facility in Co. Dublin. When the machine first arrived, we were hugely impressed with the modern design and robust construction. For a machine in that class range at more than 70 tonnes, we expected it to be quite complicated to set up and get operational, but in fact the opposite was true. The machine was crushing within minutes of being tracked off the transport truck!

“The machine was fitted with its own on-board generator,” Ed added, “which, when coupled with the electric drive system allowed the machine to run very quietly and extremely smoothly for that size of primary jaw.

“In the limestone quarry, the Premiertrak 600E was using around 27 litres of fuel per hour and when all the calculations with the throughput figures were done, the overall cost per tonne was an awful lot lower than we imagined and astounding for that size of machine. When you see this machine in the flesh, it’s obvious that Powerscreen have used their years of knowledge and experience to design and engineer a machine will perform and last.”

Powerscreen also recently unveiled the Powerscreen 1150 Maxtrak cone crusher.

Damian Power, Powerscreen Global Product Director, said, “We are excited to add the 1150 Maxtrak model to our cone crushing range. Packed full of new features, the 1150 Maxtrak crusher will continue to push the boundaries in the crushing and screening industry. Due to the feedback we have received during testing, we have every confidence that this machine will be a success.”

Crush Ltd has been putting the 1150 Maxtrak cone crusher through its paces with extensive testing in preparation for its launch later this year. While on site at their quarry in Wales, Crush Ltd has been primarily using the 1150 Maxtrak unit for the crushing of gritstone to produce 6mm (1/4″), 10mm (3/8″) and 14mm (9/16″) chips on final products. Ben Sherratt from Crush Ltd explained, “Typically, we had been using a crushing and screening train consisting of a jaw, two 1000 Maxtrak cone crushers and a Chieftain 2100X screen. When the 1150 Maxtrak cone crusher was substituted for the first 1000 Maxtrak unit, the plant’s output surged by an additional 30%.” In a second application, Crush Ltd has been using the 1150 Maxtrak crusher to produce a 6N hardcore crusher run product. Ben added, “With the 1000 Maxtrak unit in this application, we had been producing around 1200-1300 tonnes per day. With the 1150 model, we are now at 2100 tonnes per day.”
