Published 27/12, 2021 at 12:11

Sandvik Mobile Crushers and Screens has launched its new QI353 mid-size impactor, the first of its new 3rd generation 3-Series. Designed in response to customer research, the QI353 has been developed to deliver more productivity, uptime, efficiency, flexibility, connectivity and safety.

The QI353 features a ground up new mid-size track platform and ‘Prisec’ impact crusher. Targeted at quarry, recycling and contractor segments, the QI353 is designed to provide more uptime. With the operator in mind, the 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 featuring ‘Optik’ intuitive user experience which comes with colour visual display, easy navigation and total integration for troubleshooting, diagnostics and support.

The QI353 is said to be able to process up to 400t/h. Its feed arrangement includes a new feed hopper with curved heavy duty sides for greater capacity and tapered feed arrangement to reduce blockages. 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 QI353 is a new mid-size Prisec impact crusher, which a feed opening of 1,170mm x 730mm and a rotor diameter of 1,150mm. 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 and efficiency

The QI353 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 the feeder drive ensures continuous crushing, whilst a larger pre-screen provides effective removal of fines. In addition, the QI353 benefits from extended service intervals and larger on board fuel storage to extend intervals between refuelling. It has been designed to consume less energy, with its double deck pre-screen ensuring maximum scalping capability thus preventing any undersize material passing through the impactor. This maximizes crusher throughput, reduces wear costs and energy consumption. The machine is also said to require 40% less hydraulic oil per service and benefits from extended hydraulic oil replacement intervals. The QI353 is also fitted with the latest emissions compliant power pack for maximised performance and cost efficiency.

Boasting a high degree of flexibility to suit any application, the 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 bypass chute under the pre-screen. The QI353 comes prepared to accept Sandvik’s new enhanced HS323 hanging screen module, offering the flexibility for the crusher to operate in open or closed circuit.


More connectivity

The new automation system with Optik intuitive user experience includes simplified operation controls and total integration with Sandvik’s ‘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 utilised. One of the new additions to the plant is the availability of optional belt scales. These are fitted to the product conveyor and will enable productivity data to be displayed on the user interface and via My Fleet for monitoring, enabling full control of the machine’s output.

With operator safety paramount, Sandvik states that is has incorporated a new access platform under the feeder and pre-screen as well as a three sided platform for service and maintenance. A lifting beam, jib and tackle are provided, as well as the patented rotor turning device to ensure operator safety when removing, rotating or installing hammers. A height adjustable overband magnet is available and all conveyors can be conveniently lowered for inspection and servicing purposes. Enhanced safety features are embedded within Optik including visual warnings and emergency stop locations.
