The QI441 Prisec™ is the latest addition to Sandvik Construction’s Premium range of tracked impact crushers, providing customers with an extensive mobile crushing solution whatever the application. Available in a heavy duty and compact format, all models possess high reduction ratios, providing customers with optimum product shape, high productivity, low wear, easy maintenance and a low cost/t.
The QI440 is already proven in its class for offering superb product shape, high productivity and ease of maneuverability. The new Premium QI441 model is now set to offer customers unparalleled flexibility in both primary and secondary applications through the use of the revolutionary CI421 Prisec™ Impactor box.
The patented Prisec™ crushing chamber has been designed by Sandvik Construction to enable the base crusher to be easily switched between primary and secondary mode, thereby giving the customer virtually two machines from one unit. The two hydraulically assisted curtains can be readily adjusted to allow the production of a wide range of high quality product sizes.
The new QI441 model also retains many beneficial features introduced on the QI440, such as:
- Direct drive system for optimum fuel economy and low operating costs.
- Large feed hopper with highly efficient pre-screening.
- Underpan feeder to protect the main product conveyor from high velocity material from the rotor.
- User-friendly PLC control system and colour screen for ease of operation.
- Inlet opening may be raised by remote control to alleviate blockages.
- Overband magnet, pre-screen and ceramic blow bars as standard.
- Low wear, easy maintenance and a low cost/t operation.
The versatility of the QI441 is further ensured by a comprehensive range of optional extras that allow the crusher to match the demands of the customer’s specific application. These include a unique Doublescreen double-deck hanging screen with recirculation system. This 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 onboard 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.
