QE341 Scalper/Screen

The new QE341 represents the most advanced and complete mobile scalper yet designed. Customer feedback has been an integral element in the development of this model and the most sought-after features have been incorporated into this unit.
Our goal of minimum user intervention means that we have focused on delivering huge stockpiling capacity, with ease of stockpile removal, uninhibited material flow and ability to handle the toughest of material with an apron feeder fitted as standard.
The 16’ x 5’ / 4.7 x 1.5 m screenbox is highly aggressive with 9mm throw operating at over 1000 RPM. This ensures that even the most difficult materials can be handled effectively.
Whether it’s working before or after a primary crusher or as a stand alone unit, the QE341 is designed to deliver high production with clean separation, the exceptional on-board conveyors ensure that the delivery is in harmony with the throughput.
Applications include screening quarry overburden, blasted rock, landfill mining, C&D waste, aggregates, slag heaps, environmental clean-ups and topsoil/subsoil.

QA450

Former name: Extec S-7 Screen
Building upon the highly advanced features of the existing doublescreens, the QA450 introduces a triple deck screen box, and extra side conveyor that enables it to produce up to a total of 5 product materials. Designed for maximum productivity, the QA450 incorporates a large feed hopper, a pair of large screen boxes and extended conveyors that afford massive stockpiling capabilities. The screenbox in the QA450 makes use of the tried and tested doublescreen design, but now with a unique triple deck design cementing Sandvik its position as a true world leader.

Features and values

  • Triple deck doublescreen with four product conveyors allows five products to be produced
  • Capable of working alongside large jaw crushers, yet precise enough to produce accurate aggregate products
  • Modern chassis design ensures in-built machine quality and strength for maximum up-time
  • Designed for optimum fuel economy and low operating costs.

QA440

Former name: Extec S-6 Screen
Sandvik QA440 delivers true static screen productivity in a durable, mobile package. Designed with maximum productivity to the fore, the QA440 incorporates a large feed hopper, a pair of large independently angled screen boxes, and extended conveyors that afford massive stockpiling capabilities. This highly productive machine is carried on a large, durable chassis that is designed to withstand the rigours of a large quarry or recycling application. A self-loading hydraulic bogie provides an independent transport capability without the need for low loaders.

Features and values

  • Unique, independent doublescreen box design allows for precision screening, but huge screening area enables high volume production
  • Capable of working alongside large jaw crushers, yet precise enough to produce accurate aggregate products
  • Modern chassis design ensures in-built machine quality and strength for maximum up-time
  • Designed for optimum fuel economy and low operating costs.

QA331

The Sandvik QA331 Tracked Screen is a robust, highly durable machine, designed specifically for the recycling and contractor market. QA331 incorporates a 4.25 x 4.5 m (14′ x 5′) two bearing screen box with an adjustable screening angle. The bottom deck has an extra 6 degree screening angle for ultimate screening performance. This feature, coupled with the larger screening surface area, and increased throw on the screenbox, enhances screening efficiency and capacity through the actual screenbox itself.

Features and values

  • High production rate through large screening area, high frequency double deck screen and a six degree inclined angle on screen-box to produce a “banana” effect
  • Suitable for working at the quarry face, inner city development or recycling centre
  • Modern chassis design ensures in-built machine quality and strength for maximum up-time
  • Designed for optimum fuel economy and low operating costs

Sandvik QA340 Screen (Extec S5 screen)

Make: Extec/Sandvik

Year: 2011

Hours: New

Price: Sold- More to choose from!

The QA340 (S-5) is the original doublescreen and was the first screener produced with the doublescreen technology.   It represents the greatest innovation in mobile screening systems as the QA340 (S-5) resolves the conflicting principles previously associated with providing larger screening areas on mobile plant.

Although possessing many customer focused features, at the heart of the QA340 (S-5) is the Doublescreen Box. This enables the screener to incorporate such mould breaking features as:

  • Independent screen-box slope
  • Independent screen-box vibration
  • Independent screen-box amplitude
  • Independent screen-box speed

All resulting in fantastic output of accurate, quality products!

The Doublescreen box allows for over twenty different screening angles. Screening efficiency is maximized as material flow is directed by the angle of the screen box resulting in:

1. A steep angle for the primary screen-box ensures that the majority of the material is processed in the initial impact area.

2. The majority of the undersize is removed during initial impact.

3. Only near-size material passes to the secondary screen-box. This may be set flat enough to ensure any remaining material is screened efficiently.

4. Clean gradings, at very high out put, are produced as material is exposed to large screening area.

With all the above features the QA340 (S-5) promises to be the ultimate mobile screening system for the truly serious contractor or quarry operation. The QA340 (S-5) represents the greatest innovation in mobile screening systems as it finally resolves the conflicting principles previously associated with providing an immense screening area on truly mobile plant.

The primary and secondary boxes consists of two 8 x 5 decks.  This provides the customer with a 16 x 5 top deck and a 16 x 5 bottom deck.
