Hartl sees double

Hartl Crusher has launched its new HSP 3300, which it claims is a highly mobile compact two deck screening plant with a maximum throughput of 90 cubic metres per hour (3,180 cubic feet per hour). According to the company, it will find use in natural stone processing as well as in the classification and refinement of recycled materials. The screener is also perfect for use in road construction and earthworks as well as forest road construction and excavations.

"The main advantage lies in the screen box's electro-hydraulic drive which provides more power than comparable pure electric drives and is also much more robust and durable. At the same time, with this drive system the speed of the screen's rotation is continuously variable and a reversal of rotation direction is also possible," said Georg Haberfellner, chief designer at Hartl Crusher.

He went on: "The screen box is spring mounted and thus provides the best power transfer for both screen decks. All components are high quality and are designed with component protection in mind."

Hartl offers HCB conveyor belts to go with the screen box that are electrically driven and have a maximum discharge height of 2.5 m (8.2 ft), with a folding mechanism that provides easy belt changing as well as reducing transport dimensions to a minimum. When directly fed by a bucket crusher, up to three categories of material can be produced and in combination with a bucket screener this can even be increased to four.

The new screening system will be on show at Intermat in Paris at the end of April on stand C033 E2 & E2 Paris Demo G04.
