Offering 400t per hour processing speed, QI353 model designed for high productivity and high uptime

Sandvik has announced the launch of its new mid-size impactor QI353, a new crusher built with more productivity, uptime, efficiency, flexibility, connectivity and safety at the forefront of its design.

The Swedish company said that the QI353, the first of its new 3rd Generation 3-Series products, has been designed in response to customer research, and features a new, ground-up, 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, said the manufacturer.

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, Optik, with intuitive user experience. With a colour visual display, easy navigation and total integration for troubleshooting, diagnostics and support.

The new crusher QI353 has been designed with productivity in mind and can process up to 400mtph/441stph. 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 1170mm x 730mm / 46” x 29” and largest rotor diameter 1150mm / 45” 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.

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

The QI353 has been designed to consume less energy, with its double-deck pre-screen ensuring maximum scalping capability and preventing any undersize material passing through the impactor. This maximises 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 10,000hrs 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.

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 Sandvik’s new enhanced HS323 hanging screen module, offering the flexibility for the crusher to operate in open or closed circuit.

The HS323’s 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 1, 2 or 3-way split screener, as well as a highly productive and efficient impact crusher.

The new automation system with Optik control system with 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 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.
