Sandvik UJ440i is an intelligent, fuel-efficient and user-friendly mobile jaw crusher available for the global market. It is designed for trouble-free operation thanks to its onboard integrated ‘intelligence’ system. This allows for simplicity of operation, as the UJ440i is continuously and automatically monitored by the control system that operates the unit, enabling full optimisation of production.
The UJ440i is equipped with the Sandvik CJ412 with a large jaw size of 1,200 x 830 mm, which offers great size reduction and consistent performance. Production is maximised through the generous feed opening coupled with a hydraulic close side setting (CSS) that enables rapid changes through push button operation. The jaw also comes complete with a level sensor as standard to maintain optimum material flow in the chamber when crushing.
The UJ440i tracked mobile jaw crusher is fully operated via radio remote control and can be ready to work in less than 20 minutes on site, with safe set-up from ground level. The hopper walls are hydraulically foldable and automatically locked in position, and the main conveyor has an adjustable discharge height. The unit is also fitted with rubber lined impact zones to reduce wear, minimise maintenance downtime, as well as reduce noise.
The model is very versatile and can be offered in three different variants to suit specific application: Comfort – with grizzly feeder for crushing on clean rock and gravel; Classic – with grizzly feeder and live under screen for crushing rock and gravel; and Trend – with pan feeder and live pre-screen for crushing on clean rock and gravel with a lot of fines.
Within the U-440i product range, Sandvik also has its cone crusher offerings such as the UH440i and US440i models, which are built to the same high specification and feature many of the same customer benefits as the UJ440i. This range of equipment has proved to be the ideal crushing solution in aggregate production, surface mining and quarried rock.
