Material of Construction • Side plates: Fully killed steel plates • Cross members: Rectangular hollow sections ( cold formed ) • Corrosion resistance: Rubber lagging on cross members • Body painted using structural grade epoxies No crevices for collection of moisture is ensured • Wear resistance: The feed and discharge lips & the wear prone areas are lined using Special compounds of reinforced rubber Salient Features The Hi-Freq screens are powered using dual unbalanced motors to give a linear motion flow. These screens have an inclined back plate which is at 45-65degree angle and it rapidly removes significant amounts of feed water. The bed of solids formed on the screen surface lets the water percolate through the screen openings and the bed is compacted during vibrations. This in turn squeezes the water out of the fines bed as it is conveyed up the deck. • No welding on the side wall plates. Fully bolted structure. • Welding on cross members are stress relieved prior to assembly. • Wear and corrosion lining are standard to all equipments. • Counterweights are guarded for operator safety. • Screening deck can be tensioned from the sides with ease and can be replaced/removed without much efforts. • Machine painted using special corrosion resistant paints for longer life. Applications The Hi-freq screens finds itself suitable for Dewatering Fine material after thickening or after being discharged from water only cyclones. The screens have wear resistant screening decks and the product is discharged as cakes. The screen mainly finds its application in dewatering of coal and sand after washing. Capacities The Hi-freq screens are Available in single deck configurations and can have capacities ranging from 10 tph to 50 tph each installation. Drive The hi-frequency screens work on the principle of Low strokes and high RPM thus the screens have twin unbalanced 4 pole vibrating motors imported from Germany. The drives are lubricated for life and does not need to be lubricated during its entire lifetime. No external drive motor is required to operate the screens.
