The family owned company Hector Van Moer and Sons was on the lookout for an innovative solution to recycle construction and demolition (C&D) waste. Traditionally, the recycling industry uses an impact crusher, but the owner Dirk Van Moer was looking for a more sophisticated solution. “In our C&D-waste there are often large pieces of steel which will lead to a lot of downtime when using a percussion crusher. This is why we prefer a jaw crusher”. Van Moer started the search for a suitable solution to fit their requirements and found it at OMTRACK, a company belonging to the KEESTRACK group, as the OMTRACK crushers are equipped with the patented Non-Stop System (NSS) to guarantee a continuous production process and to protect the crusher against an uncrushable feed. If a large unbreakable piece enters the crushing chamber, the jaws will open automatically and then reset to the original setting.
Van Moer uses their jaw crusher mainly at their own sites for demolition, earthworks and soil remediation projects and they have to follow strict quality guidelines for the Belgian COPRO approval. Copro approved products can be sold as a commodity. When Van Moer visited OMTRACK in Italy they presented all their requirements.
The result was on show during the Mat Expo exhibition in Belgium (Fig. 1). The new Giove jaw crusher (1100 x 750 mm / 3’7.3” x 2’5.5”) in closed circuit with easy removable post screen of 1200 x 3000 mm / 3’94 x 9’10” (Fig. 2), a pre-screen with side discharge conveyor (Fig. 3), a hopper with extended hopper walls (Fig. 4), a highly effective overband magnet, a spray-dust suppression system, radio remote control, central greasing system, diesel fuel pump and an optical weighing system with data transfer for remote inspection of the production capacity. “If we crush on location we save on transport and dumping costs. In addition, we can reuse the material on the spot by using the post screen which saves on commodities. Screening could be done by a separate screener but we have chosen to integrate the screen to save transport costs and space on site.” According to Dirk Van Moer, because of these cost reductions, he believes that a return on investment (ROI) of 5 years is realistic, which is very good for a machine which is not used daily. This client customised Giove CC, which is painted in the company fleet colours, weighs 62 t of which the crushing unit weighs 19 t. With Van Moer the Giove CC produces 130 t/h at CSS 45-46 mm. Of this amount, there are ± 100 t Copro approved crushed aggregate of 0-40 mm and ± 30 t natural fines of 0-15 mm. The fuel consumption of the Cummins engine at 1850 rpm is 0.20 l/t produced.
