Guangdong- based Long Ying Construction Engineering has become the first customer in China to purchase Sandvik Mobile Crushers and Screens’ QI442 HS horizontal shaft impact crusher.
Said to be able to provide highly accurate material reduction at high rates of throughput, the crusher can also, through Sandvik’s advanced modular hanging screen, to produce up to three products where and when required.
Long Ying Construction Engineering services the requirements and needs of the local construction industry, operating in areas such as demolition, construction machinery rental, civil engineering contracting, tunneling, landscaping and environmental engineering, as well as supplying aggregates arising from its multi-faceted operations.
The company now employs around 30 full time staff and operates a full fleet of equipment comprising 15 excavators, five wheeled loaders, stationary trommel screens, three mobile crushing and screening trains and around 12 haulage trucks.
Sandvik Mobile Crushers and Screens’ authorised distributor, POTA Environmental Technology,recommended the QI442 HS, one of the Sandvik’s latest developments, when Long Ying looked to improve its crushing and screening equipment.
Sandvik says the QI442 HS supplied comes equipped 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 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 whilst an under pan feeder located beneath the impactor protects the main conveyor belt from the material exiting the impact crusher.
One of the benefits incorporated into the QI442 HS is the optional double-deck modular hanging screen system, which is interchangeable and offers the flexibility for the crusher to operate in open or closed circuit.
Long Ying is now using its state of the art crusher to crush mainly construction and demolition waste with a maximum feed size of 800 mm (31.5 in), producing two core products: 0-10 mm and 10-40 mm, at an average production rate of 200 t/hr.
