Sandvik's new UH450E track-mounted crushing and screening system
Sandvik Construction says its Steinexpo 2014-launched UH450E is a “world-class track-mounted crushing and screening innovation”. The new model is said to be the ideal economical choice for aggregates contractors looking to achieve the highest quality end products, at maximum production capacity, combined with low operating costs.

Built to customer’s requirements and with the highest quality components, the UH450E can operate via electrical mains or an on-board diesel generator. Truly versatile and capable of working either as a secondary or tertiary unit, the new crushing and screening solution’s cone and screen both come with a choice of crushing chambers and screening media respectively.

The UH450E has been designed with a pre-screen to optimise production and product quality, with the pre-screen also offering the operator flexibility in directing the flow of material. A predetermined portion of the flow can be extracted on a side conveyor, be fed to the crusher or bypass the crusher. The coarse material is fed directly into the Sandvik CH440 cone, which is a well proven design and renowned for its reliability.

Material is then fed into the newly developed, highly effective, Sandvik product screen via the recirculating conveyor. This unique design operates via a tension-friction belt and enables excellent feed to the screen. The aggressive double-deck banana-styled screen features a steeper angle at the feed end to accelerate the removal of fines and a gentler lower section increases screening accuracy.

The complete process is fully automated, well-balanced and with a high level of “intelligence” on board to maximise production, quality of material and minimise downtime. This includes a level sensor over the crusher chamber to keep the crusher choke fed, and Sandvik’s ASRi - Automatic Setting Regulation - as standard.
