The latest update in Sandvik 2 Series portfolio is the QI442 track mobile impact crusher. The machine features the newly developed CI621 Prisec Impactor, which comes with several innovations for improved efficiency and safety during maintenance, as well as being able to operate in either primary or secondary crushing mode.
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 greater range of adjustment in curtains. This allows greater usage of wear parts and maintains tighter settings in the secondary position.
One of the benefits incorporated into the QI442 is the optional modular hanging screen system. Recently launched on Sandvik mobile cone crushers, this system is interchangeable and offers the flexibility for the crusher to operate in open or closed circuit. The innovative 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 degree) of up to three products on the floor, or removal (180 degree). The tail section can be raised hydraulically to give improved ground clearance for transport when loading or unloading.
The QI442 comes with Sandvik My Fleet remote monitoring system as standard. My Fleet has been developed to help customers 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 and in turn maximising return on investment.
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, offering the flexibility to suit any application and the underpan feeder drastically reduces spillage generally associated with impact crushers.
Other features include Cat C13 diesel emissions compliant engine with direct drive heavy duty wet clutch for maximum power delivery and fuel efficiency; and ease of operation with a user-friendly PLC control system and colour screen.
New distributor in Malaysia
Sandvik Mining and Rock Technology has recently appointed Wedago (WDG) as its new sole distributor for mobile crushers and screens in Malaysia. WDG will also provide aftermarket support for its customers.
WDG Resources Sdn Bhd, a member of Wah Seong Corporation Berhad, employs personnel with more than 30 years’ expertise and experiences in the power generation and construction equipment industries. The newly added Sandvik products are expected to complement WDG’s existing offerings.
WDG’s facility is located strategically in Bukit Kemuning and the company has a dedicated team of service personnel with eight branches throughout Malaysia - in Kelantan, Johor Bahru, Kuantan, Klang Valley, Butterworth, Sibu Kuching and Kota Kinabalu.
“We are delighted to work with such a trusted supplier,” said Paulo Prazeres, sales manager for Sandvik Mobiles in Asia. “Their industry expertise and local customer knowledge provides great synergies with our products. This, combined with their strong aftermarket support, will enable us to take our growth to the next level.”
This new distributorship reinforces Sandvik’s commitment to customer focus, through the provision of locally focused support whilst at the same time allowing customers to benefit from dealing with a global company.
Goh Eng Hooi, group CEO for Infrastructure Trading and Services Division that owns WDG Resources commented, “The appointment of WDG as a Sandvik dealer will have a positive impact on the Division’s structure in terms of product diversification that is synergistic to our existing market sectors. This aligns with our related business in building materials and infrastructure equipment, as many of our current customers and suppliers also operate in quarrying, batching plants and related industries in which Sandvik has presence.
