The QA331 is a brand new state of the art mobile three way split screener based on the Sandvik`s model QA330. The new model now comes with improved screening capacity, and is a robust, highly durable machine, that has been designed specifically for the recycling and contractor market.
At the heart of the QA331 is a 4.27 m x 1.52 m (14 foot x 5 foot) two bearing screen box that possesses an increased six degree screening angle built into the bottom deck of the screen. This feature, coupled with the larger screening surface area, and increased throw on the screen box, enhances screening efficiency and capacity through the actual screen box itself. The QA331 provides high production rate through a large screening area, high frequency adjustable angle, a double deck screen and a six degree inclined angle on screen-box to produce a “banana” effect.
Units are fully capable of working at inner city developments or at a recycling centre. A modern chassis I-beam design ensures maximum durability for arduous conditions, and units are designed for optimum fuel economy and low operating costs.
Sandvik also recently announced the launch of their new mobile, track-mounted QH440 cone crusher (2012).
