For the last 20 years Glenn Sutton and Sutton Services Ltd have been providing a high quality demolition and dismantling service in East Anglia. Due to an increasing work load, and in order to improve efficiency, Glenn Sutton decided it was time for the company to upgrade their crusher.

East Anglia based Sutton Services Ltd is a leading demolition contractor and general building dismantlers that have rapidly expanded in recent years. This has been achieved by drawing on a wealth of experience in the demolition industry, but at the same time proudly minimising environmental impact. Directors and staff possess a vast working knowledge of the industry; it's ever evolving nature, with a key feature of their success being the emphasis placed on regular liaison with the relevant authorities. This has enabled the company to keep abreast of changes to working practices, thus aiding in implementation on site.
In order to ensure operational efficiency, minimal environmental impact, and compliance with changing regulations, Glenn Sutton, Managing Director of Sutton Services, realised that in the company’s 20th year a new crushing solution would be needed if they were to maintain competitive advantage. As Glenn explains, “When you are in business you can’t sit back and rest on your laurels. Over the last 20 years we have developed a loyal and expanding customer base who expects the very best in service. Although I’ve tried to ensure that our equipment is the best out there it was becoming obvious that we needed a more modern and compact crushing solution.” With this need identified Glenn sought out the best value machine on the market, and looked at various crushers from differing manufacturers before settling on the new QJ241 from Sandvik Construction. As Glenn continues – “The QJ241 is meant to be the best out there, and my customers deserve the best.”
The QJ241 is Sandvik’s smallest mobile jaw crusher; of dimensions suitable for low loader trailers, and weighing just over 34 tons, it lends itself perfectly to varied operations at construction sites. The single-toggle crusher has a feed opening of 1000 x 650mm facilitating production of up to 225 tons per hour depending on the material and the required final material size. In Sutton’s recycling operation 120 to 150 tph may be achieved when producing a 0/70mm end product. Furthermore the reversible jaw crusher accepts a maximum feed size of 500mm, and the fitment of a hydraulic wedge adjustment allows a CSS (closed side setting) range of 50 to 150 mm.
A major reason for Glenn Sutton’s decision to go with Sandvik is that the QJ241 has proved an ideal tool for efficient long-term use at construction sites, recycling facilities and small quarries. One of its main assets in these operations is the extensive steel pipe work used in the hydraulics, which provides superior heat dissipation and a maintenance free sealing solution. Additionally the displays, controls and service points are close to ground level, or easily accessible via platforms. The machine also possesses several practical features including a standard fitted hydraulically driven cooling fan, with auto reverse, to back-flush dust from the radiator or the central auto lube on the jaw. Furthermore, and depending on operator requirements, the crusher can be operated remotely by wireless control or via umbilical cord.
The use of a modern PLC system on the QJ241 controls both the level sensor at the crusher in-feed, and the RPM of the main conveyor. The hydraulically driven feeder with grizzly allows automatic control of the feed rate from the large hopper. Additional use of hydraulics sees a hydraulic raise and lower facility on the 800mm wide tail conveyor, which provides clearance for the overband magnet thereby guaranteeing smooth and continuous discharge.
A key feature of all Sandvik mobile crushers, and the QJ241 in particular, has been the minimisation of operating costs. This has been achieved via load optimised control of the hydraulics, and the use of a modern 168-kW CAT C7.1 Acert engine that is compliant with EU Stage IIIb emissions. These developments have led to a signifgicant decrease in fuel consumption even in high-capacity operations. The benefits have already proved evident for Glenn Sutton as he states that after 150hrs of operation - “Compared with previous crushers we have used the QJ241 now achieves in all applications 25% more output and consumes 30% less fuel.”
Sutton Services and Glenn Sutton represent the new breed of demolition contractors who not only aim to complete projects to the highest standard possible, but also aim to do so by using the very latest equipment, thereby maximising on site health and safety, whilst minimising their environmental footprint. The new Sandvik QJ241, the first in East Anglia, represents new standards of performance geared to both end material quality and project profitability, and its purchase by Glenn Sutton marks the 20th year of Sutton Services Limited perfectly.
