Hartl Crusher has added a compact two-deck screening plant to its range of material-processing equipment.

The mobile screen plant, designated HSP 3300, has high screening efficiency, said Georg Haberfellner, chief designer at Hartl Crusher. Depending on the material, throughput can reach up to 90m3/hour.

“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 Haberfellner.

“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.”

This product is used in natural stone processing as well as in the classification and refinement of recycled materials. The screener is also able to be used in road construction and earthworks as well as forest road construction and excavations.

The HSP 3300 adds to Hartl’s existing range of excavator-mounted hydraulic attachments for crushing and screening.

When directly fed by a bucket crusher, up to three categories of material can be produced, in combination with a bucket screener this can be increased to four.

Hartl also offers electrically driven conveyor belts which provide a maximum discharge height of 2.5 m. The folding mechanism guarantees simple belt changing and reduces transport dimensions to a minimum. The screening system, including conveyor belts, has an electrical power consumption of only 14kW.

The Hartl range is sold by FAMCO in the GCC.
