Cosben has introduced Eyelets that will be fitted at the flange for every section. These are for passing Electrical Cables. This will ensure that the Electrical cables do not hang down from the screw causing a safety hazard. The Eylets are wide enough to accommodate a PVC Pipe if you decide to lay your cable through it. PVC Pipes are recommended for running the cables along the Screw Feeder / Conveyor so that the cables are protected by some degree against the weather.

Isolation Limit Switch at the Inspection Hatch of the Screw Feeder/ Conveyor

Screw Feeder/ Conveyor during inspection checks, maintenance & servicing. This ensures that there aren’t any mishaps or accidents while the personnel is servicing the Screw Feeder / Conveyor. The switch will be fitted on the 1st inspection hatch which is the most vulnerable point for Safety failures.

Eyelets for cables / Cable pipes

The Zero Speed Switch at the end bearing allows an operator to know whether the screw is currently in operation of not by looking at the signal on his control panel. This is useful in bigger plants where the screw may be located away from the control cabin and out of the line of sight of the operators

Zero Speed Switch at Endbearing

Screw with Safety Accessories

The Isolation Limit Switch, cuts off the power to the

Integral part of any batching plant NOT ONLY to keep pollution under check BUT ALSO to recover& recycle the dust/powder material back into the system. Available with 2 types of cleaning arrangement – air pulse jet cleaning OR Vibratory cleaning in SILO TOP mounting or ground mounted version with fan, hopper and ducting (client scope) for cyclic de-dusting of more than 1 silo.
