Sandvik launches fully electric heavy jaw crusher
04 October 2023
Sandvik Mobile Crushing and Screening has launched a fully electric heavy jaw crusher model, as part of its continued “make the shift” strategy to develop products that offer greater sustainability.
The new Sandvik UJ443E heavy jaw crusher is a tracked machine that is designed to handle hard and abrasive rock, for applications in the aggregates, construction, quarrying and mining sectors.
While Sandvik has not yet revealed the exact specifications pertaining to the crusher’s operational capacities, when compared to the manufacturer’s previous comparable models, the fully electric UJ443E is said to offer up to a 30% reduction in fuel consumption and up to a 30% increase in material throughput.
The UJ443E is fitted with the latest generation CJ412 jaw crusher unit, electric final drives and an onboard genset.
The genset allows it to be powered by either an external electricity supply, HVO or diesel.
Sandvik said: “Operating whilst connected to the external electric source can bring several advantages, including lowering running costs, extending drive train service intervals, reducing time spent refuelling, reducing onsite emissions and lowering noise levels.
“The fully electric track drives also decrease the use of hydraulic oil on the plant by up to 91%,” said the manufacturer, adding that the machine also benefits from “better control and agility when tracking and loading”.
The UJ443E model also has a 125-Amp downstream connection that enables equipment users to operate a downstream plant unit, such as a screener or scalper.
According to Sandvik, utilisation the downstream configuration can decrease fuel consumption by up to 20%, compared to running separate units.
As well as boasting quick set-up and close-down times, the model is equipped with a new crusher unblock system to further minimise down time, and it features a redesigned feed station with a hydraulic lift function for improved maintenance access.
“Its new modular feed station includes a larger hopper, two feeder options with larger grizzly cassettes and an optional under screen for greater natural fines extraction before crushing, allowing operators to optimize their process flow depending on feed conditions and material,” said Sandvik.
