Vibrating screens · Authorized Hewitt Robins dealer
Vibrating screens, 1.25 to 3.6 metres wide
Synergy Services Corporation supplies Hewitt Robins vibrating screens across India as an authorized dealer. The standard range runs from 1.25 to 3.6 metres wide and 2.4 to 9.6 metres long, in single and multi-deck arrangements, with capacities to 4000 TPH on the widest machines. Screens are of bolted construction so a single component can be replaced rather than the whole frame, and most replacement machines are custom designed to fit an existing structure.
