CRUSHING/SCREENING

‘train’ makes its African debut

The dual powered J-1175 jaw crusher incor- porates the robust JW42 high performance electrically driven single toggle jaw chamber and a heavy duty VGF feeder to give optimum production. Additional benefits are said to include rapid set up time, ease of maintenance, high reduction ratio, high output capacity and an advanced electronic control system. The jaw chamber is hydrostatically driven which offers operators reversible operation for clearing blockages that may be experienced in demolition and recycling applications. The hydrostatic system also provides vari- able chamber speed to suit given applications. Chamber CSS (Closed Side Setting) adjustment is fully hydraulic and can be changed in a mat- ter of minutes. The dual powered C-1540 cone crusher incorporates the proven Terex ® 1000 cone crusher with direct electric drive, automatic tramp relief and hydraulic closed side setting (CSS) adjustment. The C-1540 can be fitted with an optional patented pre-screen module which allows fines materials to bypass prior to being fed to the crushing chamber offering bet- ter wear rates in the crushing chamber. The large hopper/feeder has an automated metal detection and purge system to protect the cone and reduce downtime by removing metal contaminants via the purge chute. The 694+ dual power inclined screen uses as standard two 37 kW IE2 electric motors which operate at 50 Hz; however, a 60 Hz and/ or IE3 set-up can be configured to suit particu- lar regions. The intuitive and user friendly electrical and

hydraulic system allows the customer to switch between diesel and electric mode at the flick of a switch. The primary operation and controls of the machine remain the same regardless of the selected power. The unit features a large 6,1 m x 1,525 m triple deck inclined screen giving a total screen- ing area of 28 m² to provide efficient screening and high capacity. Among the customers at the launch was Kinyua Gachoki, owner of Umhlali quarry in KwaZulu-Natal. “I love the idea of dual power, especially in our current South African con- text,” he said. “I will definitely look to buy one of these units when replacing my current Finlay cone crusher in the near future.” His view was echoed by Johann van Heerden of Sand Van Heerden in the Free State gold- field. “With the price of diesel being what it is, the option to run the machines on electric- ity is bound to lower our production costs, and a lower cost per tonne is what any machine owner should be aiming at.” Looking at the outlook for the dual pow- ered concept, Terry Gillham, Bell Equipment’s Director, Sales & Marketing, said that Bell was expecting to see good demand for the new mod- els. “We may be the ‘new kids on the block’ as far as screens and crushers go but – in the two years or so that we’ve been in alliance with Finlay – we’ve sold 60 units – 48 screens and 12 crushers. This probably makes us the domi- nant player in the field. We anticipate that this success will continue with the dual powered machines.” Photos courtesy of Bell Equipment
