New Sandvik QJ241 for Ben Bennett Jr
Upgraded mobile jaw crusher becomes fifth Sandvik machine at Grange Mill Quarry in Derbyshire
LONG-standing Sandvik customer Ben Bennett Jr Ltd have recently taken delivery of their fifth Sandvik mobile crushing and screening unit for use at Grange Mill Quarry in the White Peak district of Derbyshire, a Carboniferous limestone quarrying operation which the 138-year-old family-run business acquired in 1935.
The company invested in its first Sandvik unit in 2013 and has since purchased two mobile screens, two mobile crushers and a static screen. When the time came to upgrade and replace their six-year-old mobile jaw crusher, Ben Bennett Jr did not hesitate to contact Sandvik once again for the supply of a new unit, owing to the reliability and familiarity of their existing equipment, and the aftermarket support provided.
‘With proximity to the customer support centre, this was a major gain for the supply of parts and local service whenever required,’ commented company director Andy Rawson. ‘The aftermarket support has been very good. People have come out whenever we have needed assistance.
He added: ‘A lot of the work we can now do ourselves, as our operators are familiar with the equipment. That’s one of the reasons why we continue to buy Sandvik, as we don’t have to start back at square one.’
The company’s new QJ241 mobile jaw crusher is set at a CSS of 75mm and crushes the quarry’s limestone feed material down to –40mm. This is fed into a QA331 mobile screen followed by a QA140 unit for processing down to 40–20mm, 20–10mm and –10mm.
The new crusher came with the added benefit of Sandvik Optitooth jaw plates, which are now included as standard on all Sandvik Q-Range jaw crushers for extended life, increased throughput and reduced fuel consumption.
The machine also came equipped with Sandvik My Fleet remote monitoring system, as standard, together with seven years’ complimentary data access, which will help minimize operator interventions and allow the planning of service and maintenance schedules, thereby maximizing uptime and allowing optimum output to be achieved at all times.
These new extra features are in addition to the standard features of the QJ241, such as hydraulic drive, which allows the crusher to start under load; hydraulically adjustable jaw setting, to maximize output; and a jaw level sensor, to control the feed rate into the crusher with minimal operator intervention.
In accordance with Sandvik’s environmental focus and sustainability targets, the QJ241 is also fitted with the latest emissions-compliant engine, dust-suppression spray bars and onboard water pump, as standard, to minimize dust. These were important factors for Ben Bennett Jr too, owing to Grange Mill Quarry’s location on the boundary of the Peak District National Park.
