Crushing performance

High productivity and performance are claimed by Sandvik for its innovative UH421 mobile secondary crushing unit. This crusher is designed to deliver a continuous flow of high grade material and features a new, high capacity screen that allows high output. A novel feature is that the screen lies alongside the crusher while the design slows down and spreads out the material as it reaches the screen area. In tests the Sandvik SS screen was able to produce material containing no fines, despite dry conditions.

To ensure efficiency, Sandvik's new UH421 crusher is continuously and automatically monitored by the firm's ASRi, intelligent automatic setting regulation system
High productivity and performance are claimed by 325 Sandvik for its innovative UH421 mobile secondary crushing unit. This crusher is designed to deliver a continuous flow of high grade material and features a new, high capacity screen that allows high output. A novel feature is that the screen lies alongside the crusher while the design slows down and spreads out the material as it reaches the screen area. In tests the Sandvik SS screen was able to produce material containing no fines, despite dry conditions.

The crusher in the UH421 is the proven CH440 unit, which is electrically powered, features high capacity, high reduction, low manganese wear and large feed acceptance capacity.

Connection to electrical main supply or diesel generator is fast, to speed set-up. The chassis of the crushing unit has been equipped with a third self-steering axle for flexibility during relocation, and it is designed to be registered as a towed vehicle. Other features of this new piece of equipment include high mobility, dust encapsulation and filtering for the conveyors to minimise dust emissions, high separation efficiency and long service life. The feed station can easily be removed so it is possible to feed the material directly into the crusher, while the conveyors have robust drives, including external motors and angle gears.
