www.rockproducts.com ROCK products • November 2017 • 35 EQUIPMENT & TECHNOLOGY CRUSHING & BREAKING At the MATEXPO in Belgium, Keestrack presented the diesel electric B3e jaw crusher, a hybrid variant of its successful model deployed on building sites and recycling. All specific advantages of the track-mounted 30-ton machine are pre- served – budget-conscious operators can now benefit from lower maintenance costs and the opportunities for operating subsequently connected units cost-effectively. Its extremely compact transport dimensions, low transport weight and state-of-the-art jaw, 1000- x 600-mm width, have enabled Keestrack to set real standards in recent years with the B3 (formerly Argo) among 30-ton jaw crushers. Even smaller exploitation operators appreciate the crush- ing capacity of the machine, which continuously delivers top-quality results of up to 300 tph, thanks to gap widths of 45 to 170 mm (C.S.S.) that can be adjusted hydraulically at any time. Keestrack's B3, without support legs, has no trouble keeping up with the work on building sites and in quarries and, thanks to the robustly constructed tracks and the excellent chassis construction, it can also be deployed on challenging surfaces. It is these all-around characteristics, which have also made the machine very popular in the rental sector. The diesel electric Keestrack B3e crusher, heavy-duty vibrating primary screen and tracks drive are all diesel-hydraulically driven, and Keestrack's own load-sensing hydraulic control guar- antees low consumption rates of the 160-kW Volvo diesel engine (tier 4f ). A compact, lightweight 42.5 kVA on-board generator supplies the power, which further reduces the diesel operating speed (1500 rpm), and also reduces cooling requirements, risks of leakage and maintenance costs because the elimination of hydraulic motors and corresponding pipework. The reduced piping means that the Keestrack B3e now has 100 litres less hydraulic fluid, which pays off at every fluid change interval. The Keestrack B3e offers direct fuel savings and operating cost advantages when driving a subsequently connected electrical screening unit (e.g. the Keestrack K2e) or a stock- pile conveyor (connected load: 32 A (17.5 kW). With merely 4 to 5 litres increased consumption in compound opera- tions, Keestrack assesses that immediate benefits can be derived thanks to a higher added value through high-quality end-products or a clearly higher stockpiling capacity when operated by a single individual. Keestrack, www.keestrack.com KPI-JCI and Astec Mobile Screens Release Drop-In Carbides for VSI Drop-In carbides are now available for all models of vertical shaft impactors (VSI) from Kolberg-Pioneer Inc. (KPI). The new industry-standard drop-in carbide wear parts will significantly decrease downtime required for ser- vice and maintenance. "We place a huge priority on the ease and quickness of maintenance on all of our products," said Tim Harms, product manager, crushing and screening prod- ucts. "We understand that every second spent down drains valuable profits from our customers. The new carbides cut replacement time to around 20 percent of what it is with other solutions." The drop-in carbides can be retrofitted into existing VSI crushers from KPI. To learn more about the drop-in carbides or crushing and screening equipment from KPI, contact Tim Harms, tim- harms@kolbergpioneer.com.
