New impactor from Sandvik
By Lindsay Gale27 November 2014
The bauma China trade show was the stage that Sandvik used to introduce the new Premium QI440 mobile tracked crusher that uses the revolutionary CI421 Prisec Impactor box. Sandvik has redesigned the crushing chamber to allow the base crusher to easily be switched between primary and secondary mode to effectively give users two machine in one.
The new QI441 model retains many of the features of the proven QI440, such as direct drive, large feed hopper, underpan feeder, user friendly PLC control, remotely operate inlet opening adjustment, overband magnet, prescreen and ceramic blow bars as standard on a machine that features low wear, easy maintenance and low cost per tonne operation.
The versatility of the QI441 is further ensured by a comprehensive range of optional extras that allows the crusher to precisely match the demands of the customer’s specific application. These include a unique Doublescreen double-deck hanging screen with recirculation system that is of particular benefit as conventional hanging screens are often a limiting factor with high capacity impactors, forcing the customer into an expensive secondary screen purchase. However, the on-board Doublescreen system is designed to match the maximum capacity of the crusher, thus allowing the production of accurately sized products for immediate use at source from one machine.
