CREATING VALUE FROM WASTE AT QUARRIES IN THE UK
- Posted April 18, 2017
MARSHALLS plc, one of the UK’s leading hard landscaping manufacturers, have recently invested in a new Powerscreen Warrior 2100 screen, purchased via Blue Machinery Central, to work at their various quarries throughout the North West.
Initially, Marshalls took a Warrior 2100 on demonstration to gauge its capabilities, throwing it in at the deep end by tasking it with the processing of problematic waste piles. The mobile screen made light work of the heavily mixed material, separating it into –40mm, 40mm–100mm and +100mm fractions.
The –40mm was sent through a wash plant to create clean, saleable 40mm, 20mm and 10mm products, as well as grit sand and builders sand, while the oversize was re-crushed before also going through the wash plant.
After just three days on demonstration, the team at Marshalls were satisfied with the value of the machine and placed an order for one of precisely the same specification, including fingers and a 40mm deck, as well as chains to slow the movement any large oversized material.
The Warrior 2100 incorporates Powerscreen’s proven Triple Shaft technology, which is synonymous with the company’s heavy-duty mobile scalper. This innovative design ensures that the 16ft x 5ft screenbox is ultra-efficient, yet maintains a high level of throughput.
According to Powerscreen, the extreme screening acceleration means the Warrior 2100 is a class leader, particularly in sticky scalping applications, such as the one at Marshalls.
The new machine is now working with the aim of cleaning up the overburden from a sandstone quarry. Previously, it cost Marshalls to move this overburden, but now, not only is this cost being saved, but the screen is also creating a saleable stone from the recycled overburden, turning a negative cost into a positive income generator.
Commenting on the new machine, site manager Ian Manley said: ‘We were extremely impressed with the machine on demo and had no hesitation in placing the order. We are currently using a 50-tonne excavator to load the Warrior and we have had to turn the screen down as we couldn’t load it quickly enough.’
The machine will continue working in its current location before being moved on to deal with the overburden at various other quarries, which means its ease of operation and set up are also key benefits for Marshalls. Moreover, as there are thousands of tonnes to be processed, the machine is expected to pay for itself in a very short period of time.
