NOTE:

Gear motors for Screw conveyors highligth in yellow, are already at the factory

Screw conveyors highlight in green, are already at the factory and will need only some modification

and shall not be quoted.

* : Because these motors are available in the factory

Central pipe is the pipe which spiral screws are welded to it (outer diameter and thickness is given in the table)

Shaft diameter is the diameter at end of shaft in connection to the electromotor (outer diameter is given in the table)

The required screws are: G09-G11-G14-G22-K34-K36-L02-L04
