Purpose designed to process construction materials on site, Sandvik’s QI240 crusher has been designed with mobility, productivity, transportability, minimal environmental impact and user friendliness at its core.

The QI240 utilizes Sandvik impactor technology enabling the development of a fully mobile, compact impact crusher designed to either work in a primary or secondary capacity either independently or in conjunction with other members of the Sandvik product line. Although designed for the recycling of construction materials, the Sandvik impactor design enables the QI240 to be a practical impact crusher for the smaller quarry. Its compact design is useful where space and machine maneuvability are at a premium, but product shape and high levels of production are required, according to the manufacturer.

The QI240 possesses recent developments including:

• 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 maximizing throughput and reducing wear costs. This also allows a specified sized product to be produced from the natural fines conveyor.

• With a choice of grizzly, punch plate or heavy duty top deck mesh, the QI240 possesses the flexibility to suit any application.

• The QI240 is fitted with an underpan feeder which 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 main product conveyor from high velocity material from the rotor. This material is contained on the wear resistant under-pan feeder liners and gently delivered onto the conveyor belt.

• The Sandvik Pri-Sec impactor is among the most flexible impactors currently available.

• The two hydraulically adjustable apron curtains can be positioned to facilitate the machine’s operation as a primary impactor but also can be repositioned to operate as a secondary impactor to produce much smaller end products.

• The above combined with the variable engine speed gives a tip speed range of 98 to 121 ft. (30 to 371 m) per second, resulting in a wide variety of product specifications being achievable.
