Sandvik QJ341+ with pre-screen on demo at CQMS

Sandvik Mobile Crushers and Screens are delighted to announce they will be demonstrating their recent addition to the 341 jaw crusher range at CQMS in Ireland. The QJ341+ incorporates a double deck pre-screen as standard, broadening its offering of the bestselling QJ341 mobile jaw crusher in order to meet customer requirements.

The new pre-screen feature on the QJ341 provides high amplitude for excellent separation. This enables the removal of a large amount of fines, resulting in greater efficiency, higher productivity and less wear on the crusher. The QJ341+ will therefore be particularly effective in quarrying applications where a high proportion of fines in the feed material are found, as the new pre-screen ‘screens out’ this material prior to entering the crushing chamber. Test results have already demonstrated increased productivity by as much as 30% in certain applications.

To complement the pre-screen, we have designed a new telescopic natural fines conveyor, with a discharge height of 3.1m / 10’3” to deal with the increased flow of pre-screened material. The dirt chute has been designed with a steeper angle to enable a faster transfer of material, whilst also increasing the ability to deal with sticky material. The three position dirt chute allows all material passing the pre-screen grizzly to be diverted onto either the main conveyor or the natural fines conveyor. In the middle position it allows a screened product to be produced out from the fines conveyor. All of this is done by positioning the three way chute without removing any media from the pre-screen.

Other benefits include:

• Double deck pre-screen for removal of fines
• Fitted with a choice of CAT or Volvo emissions compliant engine 
• Self-locking hopper, for quick and safe set-up from ground level
• New low drag main conveyor for maximum power transfer and efficiency
• Full PLC control system and color screen allowing visual data output of all plant operating parameters
• Hydraulically raise and lower facility on the main conveyor

QH331HS also on display

Also on display at this year’s CQMS will be the Sandvik QH331 complete with hanging screen. This compact, high quality cone crusher has been designed to meet high product quality demands through the use of the renowned Sandvik CH430 Hydrocone crusher but on a tracked chassis. It offers you one of the most versatile units on the market with a choice of six different crushing chambers and a variety of bush settings. Possessing sturdy construction, its power management, coupled with the market leading CH430 cone crusher, makes the QH331 ideal for aggregate production wherever it is needed.
