Sandvik QI240 Mobile Impact Crusher

Описание: The QI240 has been developed over the last two years by Sandvik's renowned research and development programme. Purpose designed to process construction materials on site, the QI240 has been designed with mobility, productivity, transportability, minimal environmental impact and user friendliness at its core. The QI240 possesses recent developments that will ensure it becomes the impact crusher of choice throughout the construction industry:
The machine is fitted with a pre-screen to ensure maximum scalping capability in order to prevent any undersize material passing through the impactor, thereby maximising throughput and reducing wear costs. This also allows a specified sized product to be produced from the natural fines conveyor. The pre-screen has a choice of grizzly, punch plate or heavy duty mesh top deck and mesh bottom deck, providing the flexibility to suit any application. The QI240 is fitted with an underpan feeder which drastically reduces any spillage issues generally associated with impact crushers. The underpan feeder eliminates the need for skirt rubbers that are normally situated in the severe impact zone of a feed boot. The underpan feeder also protects the conveyor belt from high velocity material from the rotor. This material is contained on the wear resistant underpan feeder liners and gently delivered onto the conveyor belt. The Sandvik PriSec impactor is the most flexible impactor currently available on the market designed to meet end product specifications. Two hydraulically adjustable apron curtains can be positioned to facilitate the machine's operation as a Primary impactor, however they can also be repositioned to operate as a Secondary impactor to produce much smaller end products. All of the above combined with the variable engine speed gives a tip speed range of 30 m/s to 37 m/s resulting in a wide range product gradations being achievable.
