Sandvik Mobile Crushers and Screens has unveiled its fully electric UJ443E heavy jaw crusher. The unit is built upon a new ‘fully electric’ track platform and features high quality, reputable componentry throughout, as well as the latest generation Sandvik CJ412 jaw crusher, said the company.
The UJ443E’s 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 optimise their process flow depending on feed conditions and material.
Capable of operating in the most hostile environments, the UJ443E is designed for hard and abrasive rock applications, making it ideal for the quarry, mining and contractor segments.
A sustainable solution
Aligning with Sandvik’s ‘make the shift strategy’, the fully electric UJ443E has been designed with an increased focus on sustainability, productivity and durability, whilst retaining the look, feel and value proposition customers’ demand. Sandvik said that depending on the application, this latest model can provide customers with up to 30% reduction in fuel consumption and up to 30% increase in throughput compared to previous generation products.
The UJ443E features electric final drives and an onboard genset, meaning it can be operated in a more sustainable way, being powered by either an external electricity supply, HVO or diesel from the onboard genset. 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%, depending on the application.
In addition, the UJ443E is fitted with a 125-Amp downstream connection which enables customers to operate a downstream plant such as a screener or scalper, providing up to 20% decrease in fuel consumption compared to running separate units.
Sandvik further highlighted that the new UJ443E offers a user-friendly mobile solution, manufactured using the highest quality components onboard, with controls and maintenance points located conveniently at ground level.
To minimise downtime and maximise uptime, the UJ443E is quick to set up and close-down, and is equipped with a new crusher unblock system to clear any blockages from the jaw crusher. The unit also comes with improved access to maintenance.
The new automation system with Optik intuitive user experience has simplified operation controls and total integration with Sandvik’s My Fleet telematics solution. Diagnostic support, pre-installed guides for troubleshooting and real time information allow customers to know exactly how their equipment is being utilised.
