Sandvik launched its new QI240 impact crusher at Bauma 2010 in Munich in April. Purpose designed to process construction materials on-site, the QI240 has been developed for mobility, productivity and minimal environmental impact. It is designed to service the growing market for the recycling of construction materials, and the production of high quality aggregates from materials previously regarded as waste.
The QI240 is designed to work in a primary or secondary capacity, either independently or in conjunction with other Sandvik machines to produce the highest quality materials. Although developed primarily for the recycling of construction materials, the QI240?s compact design means that it is suitable for smaller quarries which demand superb product shape and high levels of production and where space and machine manoeuvrability are at a premium.
The QI240 is fitted with a pre-screen for maximum scalping capability to prevent any undersize material passing through the impactor. This maximises throughput, reduces wear costs and allows a specified sized product to be produced from the natural fines conveyor.
The impactor is fitted with an underpan feeder, which reduces spillage issues and eliminates the need for skirt rubbers that are normally fitted in the severe impact zone of a feed boot. The underpan feeder also protects the conveyor belt, since all of the material that is travelling at high velocity from the rotor is contained on the wear-resistant underpan feeder liners, and then gently delivered onto the conveyor belt.
Two hydraulically adjustable apron curtains can be positioned to facilitate the QI240?s operation as a primary impactor, but can also be repositioned for it to operate as a secondary impactor for smaller end products.
The QI240, combined with variable engine speed, peaks at 30 m/s to 37 m/s, which enables the production of any product specification.
With a choice of grizzly or punch-plate top and mesh bottom, the QI240 has the flexibility to suit any application.
