Belgium-based supplier Keestrack used that country’s recent Matexpo exhibition to show its new B3e jaw crusher.
The company says that the product retains all the advantages of its earlier 30 t range, which made it popular with the rental industry, while allowing for lower maintenance costs and cost-effective operation of connected units.
The diesel electric Keestrack B3e has a similar crusher, heavy-duty vibrating primary screen and tracks drive are all diesel-hydraulically driven, and the company says its own load-sensing hydraulic control guarantees low consumption rates of the Tier 4F 160 kW Volvo diesel engine (tier 4f).
According to Keestrack, the B3e offers direct fuel savings and operating cost advantages when driving a connected electrical screening unit. With only 4 to 5 litres increased consumption in compound operations, Keestrack says that immediate benefits are possible thanks to a higher added value through high-quality end-products or a clearly higher stockpiling capacity when operated by one person.
While the dimensions, weight and equipment are largely identical to the diesel-hydraulic system, the hybrid B3e positions itself equally impressively as a profitable job site crusher for rapid relocation, even for small batches.
For higher performance demands or operators with access to cost-effective electrical power, Keestrack offers its new B4e fully hybrid jaw crusher (maximum operating weight 49 t). In this case, a 110 kW electric motor is responsible for driving the crusher or it can be operated entirely from the mains supply.
