Sandvik launches next generation crusher
Published by Lucy Stewardson,
Sandvik Mobile Crushers and Screens has launched the latest upgrade in its 2 Series product offering, with the launch of its new QI442 Impactor.
The product features a 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. Like the company’s previous impact crushers, the new CI621 can be configured to work as either a primary or secondary machine, whilst the two hydraulically-assisted curtains can be adjusted to produce a wide range of high quality product sizes.
The new CI621 includes enhancements that are focused on increasing safety during maintenance and serviceability. These include a new rotor position and locking device, new hammer locking wedges for quicker removal and fitting, and a new wedge removal tool to provide safer installation and removal. The rotor bearings have also been upgraded for easier assembly and clearance setting, in addition to an improved sealing system and greater range of adjustment in curtains. This allows greater usage of wear parts and maintains tighter settings in the secondary position.
Crushing and screening in one unit
A benefit of the QI442 is the optional modular hanging screen system. Recently launched on the company’s mobile cone crushers, the system is interchangeable and offers the flexibility for the crusher to operate in open or closed circuit. The design enables setup in under 30 min. and can be fitted without the use of additional lifting equipment. The patent pending hanging screen option delivers multifunctionality as a one, two, or three way split screener, as well as a productive and efficient impact crusher.
The double deck hanging screen enables the machine to produce two screened products and recirculate the oversize back into the feed conveyor. The oversize conveyor may be hydraulically rotated for material stockpiling (90°). The tail section can be raised hydraulically to give improved ground clearance for transport when loading or unloading.
The crusher also comes with a Sandvik My Fleet remote monitoring system as standard. My Fleet has been developed so customers can know exactly how their equipment is being utilised. Through the collection and accurate monitoring of a wide array of parameters, this facilitates accurate production forecasting, ensuring that the most efficient use is obtained from equipment, thereby maximising return on investment.
The QI442 comes with a range of features designed to improve the return on investment and experience for the operator. A pre-screen is fitted, to ensure maximum scalping capability and 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 flexibility to suit various applications. The underpan feeder reduces the spillage generally associated with impact crushers.
