Sandvik Mobile Crushers and Screens roll out the latest upgrade in their 2 Series product offering with the launch of the new QI442 Impactor.
Continuing their ongoing product development Sandvik is proud to announce the launch of their new QI442 track mobile impact crusher. 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.
Pioneering crushing technology
Like previous Sandvik Prisec 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 readily adjusted to produce a wide range of high-quality product sizes.
The new CI621 includes further enhancements primarily focused on increased 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 a 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
One of the benefits incorporated into the QI442 is the optional modular hanging screen system. Recently launched on our mobile cone crushers, 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 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°) of up to three products on the floor, or removal (180°). The tail section can be raised hydraulically to give improved ground clearance for transport when loading or unloading.
My Fleet telematics
The QI442 comes with Sandvik My Fleet remote monitoring system as standard. My Fleet has been developed to help our customers know exactly how their equipment is being utilized. 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 maximizing return on investment.
The QI442 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, maximizing 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.
Key features include:
- Pioneering crushing technology for high reduction ratios
- One of the most flexible units on the market with the ability to operate in primary or secondary applications
- Many features as standard, including overband magnet, pre-screen, underpan feeder, natural fines conveyor, ceramic blow bars and remote control
- Optional hanging screen available for recirculation or stockpiling to produce two products. This is completely detachable without the need for additional lifting equipment
- CAT C13 diesel emissions compliant engine with direct drive heavy duty wet clutch for maximum power delivery and fuel efficiency
- Ease of operation with a user-friendly PLC control system and colour screen
- My Fleet remote monitoring of key parameters to help optimize machine operation
