A Keestrack crushing plant is boosting efficiency for a Belgian firm
Belgian recycling company Movarec has been using a diesel-hydraulic Keestrack R6 crushing and screening plant successfully in its operation for over 12 months. Employing the equipment has helped the firm increase throughput, while also boosting utilisation and lowering unscheduled downtime.
The Belgian firm is based at Ingelmunster near the French border and is responsible for the mobile recycling of construction and demolition waste at Monseré construction sites and customer projects. In total, the company processes up to 600,000tonnes/year of construction waste. At the 1ha crushing yard, about 70,000tonnes of high-grade granules are also produced for recycling.
At the end of last year, Movarec replaced its existing 70tonne percussion breaker with a diesel-hydraulic version of the Keestrack R6. Despite the sophistication of this package, the new equipment weighs just over 61tonnes while also being more versatile. In contrast to its predecessor at Movarec, the new machine could be transported on a low-loader without dismantling the post-screen module. As a result, mobility has been improved, downtimes are shortened and the profitability of the large breaker with a capacity of 300tonnes/hour is assured even in medium-sized processing volumes.
The equipment was supplied by Belgian Keestrack distributor for East and West Flanders, HMB. The equipment was tailored to the needs of the customer and, for example, the watering system was fitted with a compressed air device, so that the nozzles could be cleaned quickly and effectively after each use.
Another key feature is the firm’s own Neodym overband magnet which, despite a clearly lighter design, still provides high separation performance. With a weight of just 1.2tonnes, the new Neodym overband magnet is approximately 400kg lighter than a conventional model, reducing the transport weight of the entire installation.
Over 1,600 operating hours have now passed since the delivery of the Keestrack R6 equipment and the firm says it has proved its worth. Low fuel consumption from the 450kW Volvo diesel combined with the load-sensing drive have helped boost operating efficiency.
