Quarry Manufacturing and Supplies replace two large cone crushers at Hope Works cement plant
SOME years ago, Breedon’s Hope Works cement plant, in Derbyshire, contacted Quarry Manufacturing and Supplies Ltd (QMS) to provide regular servicing, spare parts, and aftermarket care for two large stationary cone crushers. The excellence of the service delivered and the quality of the QMS wear and consumable parts supplied has recently led to the quarry replacing the crushers with QMS’s own B-Series cone crushers.
Cone crushers are a key part of many quarry or aggregate plant operations, and this was certainly the case at Breedon’s Hope Works, where secondary and tertiary rock reduction was undertaken by the two large cone crushers. However, owing to a variety of factors, support for these crushers was seen as expensive and lacking in many ways. Wear parts, consumables, and general aftermarket care was not considered to be up to the task at hand, which is what led Breedon to contact Quarry Manufacturing and Supplies.
‘When we were first approached, the quarry didn’t feel it was getting the service it needed to keep production at the high level it required. We were asked to provide round-the-clock back-up to the site’s four cone crushers and other parts of the quarry operation,’ said QMS’ managing director, Jonathan Beck.
But it was not just service and aftermarket care that the quarry required, as Mr Beck explained: ‘The quarry had found that spare and wear parts and consumables had become, and were getting, even more expensive. When it was realized that we could supply, fit, and support our own range of cone crusher consumables and parts, we were asked to supply these as well, as they proved a perfect match to the existing crushers.
‘Our crusher parts were seen to be more cost-effective than the other options available, of a similar quality, and equally productive. Due to the already existing levels of QMS support being provided, it made sense to all involved for QMS to provide all the parts and aftermarket care required to maximize production.’
Due to the excellent relationship that developed between QMS and Breedon, when the time came to look at upgrading the plant and replacing the old cone crushers with new, Hope Works asked QMS if they could offer a suitable replacement. QMS seized the opportunity and provided first one, then another B-Series cone crusher. These were installed in late 2022, with QMS also providing parts, consumables, and aftermarket care for both the crushers and most of the quarry operation.
QMS’ B-Series range consists of different size models, engineered to deliver the maximum productivity with reduced operating costs. Designed, developed and manufactured in the UK, the B-Series’ robust design uses high-quality cast steel components and premium spherical roller bearings that directly contribute to reliability and high performance.
The B-Series cone crushers also feature a special hydraulic system which provides automatic overload protection by allowing the head assembly to drop, permitting the passage of tramp iron and other non-crushable material. The system then automatically returns the head assembly to its original position. The design of the hydraulic system means the crusher operates at a definite setting with less setting drift and greater stability throughout the circuit. The crusher setting is instantaneously maintained even after passing a piece of uncrushable material.
‘A blend of high motor power, large eccentric throw, and increased speed give the B-Series greater capacity than other crushers of comparable size, whilst the truly modern design creates excellent product shape and can be configured to maximize production of premium single-sized aggregates,’ said Mr Beck.
‘We believe we offer a range of crushers – jaw, impact, and cone – that are the match of anyone else in the market with regards to the cost-to-performance ratio. As we are able to support our equipment with our own engineers and have the industry knowledge to adapt any plant to suit the quarry, mine or aggregate plant’s unique requirements, we believe that our products and service provide the ideal solution, whatever the size of operation.’
