Sandvik Unveils New 3-Series Mobile Impact Crusher

Sandvik launched its new mid-size impactor QI353, the first of its new 3rd Generation 3-Series products. Designed in response to customer research, the new crusher has been built with more productivity, uptime, efficiency, flexibility, connectivity and safety at the forefront of its innovative design.

The Sandvik QI353 features a ground-up new mid-size track platform and custom Prisec impact crusher. Targeted at quarry, recycling and contractor segments, the QI353 is the most versatile, mid-sized mobile impactor available today, designed to provide more uptime than any other.

With the operator in mind, QI353 offers a user-friendly mobile solution, with controls and maintenance points located conveniently at ground level. A key highlight is the new automated control system Optik with intuitive user experience. With colour visual display, easy navigation, and total integration for troubleshooting, diagnostics and support.

More Productivity
The new crusher QI353 has been designed with productivity in mind and can process up to 400 mtph (441 stph). Its feed arrangement includes a new feed hopper with curved heavy-duty sides for greater capacity and tapered feed arrangement to reduce blockages and ensure continuous crushing. 

It also features a new pan feeder with geared drive and a larger pre-screen with improved access to replace media. At the core of the crusher is a new mid-size Prisec impact crusher, which boasts the largest feed opening 1,170- x 730-mm (46- x 29-in.) and largest rotor diameter 1,150 mm (45-in.) in its class, for higher capacity and greater energy efficiency. Adjustable apron curtains and tip speed ensure a wide range of product gradations can be achieved. Also, all plant conveyors have larger discharge heights for increased stockpiling capacity.

More Uptime
QI353 crusher features a free-flowing feed arrangement where all components in the flow path through the machine get wider, for Improved material flow. A load sensing system for feeder drive, to ensure continuous crushing. A larger pre-screen for effective removal of fines, maximizing throughput and reducing wear. In addition, the crusher benefits from extended service intervals and larger onboard fuel storage to extend intervals between refueling.

More Efficiency
QI353 has been designed to consume less energy, its double-deck pre-screen ensures maximum scalping capability and prevents any undersize material passing through the impactor. This maximizes crusher throughput, reduces wear costs and energy consumption. The machine requires 40% less hydraulic oil per service and benefits from extended hydraulic oil replacement intervals. When combined, this can be up to 64% less hydraulic oil consumed over 10,000 hours of machine usage (subject to oil sampling). The crusher is also fitted with the latest emissions-compliant power pack for maximum performance and cost efficiency.

More Flexibility
Boasting a high degree of flexibility to suit any application, QI353 is particularly useful for contractors who change jobs frequently. The natural fines conveyor can be positioned for right- or left-hand discharge with a three-position by-pass chute under the pre-screen allowing you to decide where to send your natural fines. The crusher comes prepared to accept our new enhanced HS323 hanging screen module, offering the flexibility for the crusher to operate in open or closed circuit.

HS323 enhancements include prepared-to-accept belt scales for tph monitoring on fines and stockpile conveyor belts, subframe enhanced for improved screen media access and tensioning and an updated mid-size stockpile conveyor. The unique design enables set-up in less than 30 minutes and can be fitted without the use of additional lifting equipment. The patent pending hanging screen option delivers multi-functionality as a one, two or three-way split screener, as well as a highly productive and efficient impact crusher.

More Connectivity
The new automation system with Optik control system with intuitive user experience, includes simplified operation controls and total integration with our My Fleet telematics solution. Diagnostic support, pre-installed guides for troubleshooting and real time information allows customers to know exactly how their equipment is being utilized. One of the new additions to the plant, is the availability of optional belt scales on QI353. These are fitted to the product conveyor and will enable productivity data to be displayed on the user interface and via My Fleet for TPH monitoring enabling full control of the machines output.
