Sandvik has announced the launch of its new QI442 track mobile impact crusher. According to the company, this latest addition features the newly developed CI621 Prisec Impactor which comes with a host of innovations for improved efficiency and greater safety during maintenance, as well as being able to operate in either primary or secondary crushing modes.

The new CI621 can be configured to work as either a primary or secondary machine, whilst the two hydraulically assisted curtains can be readily adjusted to produce a wide range of high quality product sizes. The machine includes further enhancements primarily focused on increased safety during maintenance and serviceability. One of the benefits incorporated into the QI442 is the optional modular hanging screen system. This system is interchangeable and offers the flexibility for the crusher to operate in open or closed circuit. 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 1, 2 or 3-way split screener, as well as a highly productive and efficient impact crusher.

The QI442 comes with Sandvik My Fleet remote monitoring system as standard. It also comes equipped with a range of customer focused features designed to improve the return on investment and experience for the operator. A pre-screen is fitted to ensure maximum scalping capability and to prevent any undersize material passing through the impactor, maximising throughput and reducing wear costs. This also allows a specific sized product to be produced from the natural fines conveyor. The pre-screen also has a choice of grizzly or punch plate top deck and mesh bottom, providing the flexibility to suit any application and the underpan feeder drastically reduces spillage generally associated with impact crushers.
