Fully electric tracked mobile machine featuring latest-generation Sandvik CJ412 jaw crusher
SANDVIK Mobile Crushers and Screens are continuing to drive the sustainability shift in the crushing and screening industry with the launch of the fully electric UJ443E heavy jaw crusher.
The Sandvik UJ443E 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.
The machine’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 optimize 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. Well suited to the quarrying, mining, and contractor segments, Sandvik say the unit is one of the most versatile and sustainable heavy-duty, mobile primary jaw crushers available today.
Aligning with Sandvik’s ‘make the shift strategy’, the UJ443E has been designed with an increased focus on sustainability, productivity, and durability, whilst retaining the look, feel, and value proposition customers’ demand. The fully electric UJ443E provides customers with up to a 30% reduction in fuel consumption* and up to a 30% increase in throughput* versus previous-generation products.
It features electric final drives and an onboard genset, meaning it can be operated in a more sustainable way, being powered by an external electricity supply, HVO, or diesel from the onboard genset. Operating whilst connected to the external electric source can bring several advantages, including lower running costs, extended drive train service intervals, reduced time spent refuelling, and reduced on-site emissions and lower noise levels. The fully electric track drives also decrease the use of hydraulic oil on the plant by up to 91%*.
The UJ443E features a 125-amp connection which allows customers to operate a downstream plant such as a screener or scalper, providing up to a 20% decrease in fuel consumption compared with running separate units.
Sandvik say the 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 minimize downtime and maximize the uptime, the UJ443E is quick to set up and close down and is equipped with a new and unique crusher unblock system to clear any blockages from the jaw crusher.
The new automation system with Optik intuitive user experience includes 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 utilized.
Summary of key features:
The fully electric track drives provide better control and agility when tracking and loading and significantly reduce the need for hydraulics on the plant and long-term service costs
Redesigned feed station with patent-pending hydraulic lift function for improved maintenance access and fixed jaw removal
Larger feed hopper is provided with a patent-pending folding and locking mechanism. The standard volume is 8m3 (11yd3). This can be increased with optional hopper extensions
Two feeder options are available. A vibrating grizzly for clean rock or a vibrating grizzly with under-screen for rock containing fines. Both are rubber lined and have significantly larger grizzly cassettes for greater fines removal before crushing
The class-leading 1,400mm (55in) wide main conveyor is now angle adjustable and extended with remote hydraulic lock out and a height-adjustable overband magnet
There is also a larger bypass chute and optional natural fines conveyor, with 650mm (26in) wide belt and a 3.5m (12ft) stockpile. It is electrically driven and folds for transport
The Sandvik CJ412 jaw crusher now has enhanced connectivity features, providing the operator with live operating parameters, heavy-duty electric drive, and onboard hydraulics for CSS setting regulation
The jaw crusher assembly can be removed for transport, which is useful in regions with restrictive transport weight regulations
The crusher unblock software reduces the need for an onboard rock hammer, reducing downtime and increasing safety on site
The alternator is sized so that a downstream screening plant could be operated from the plant's onboard genset, simplifying servicing and maintenance an improving overall fuel consumption.
