Field of application
Feeders of the PM series are used to supply a line of machine hoppers, provided that all machines process the same material and the hoppers are in a row. These conditions are mostly found in extrusion plants where different profiles are made from the same material (e.g. window profiles, tubes). The same technique can also be used as a collecting feeder with multiple inlets to combine several silos.
In connection with the dust-free feeding characteristics of the spiral conveyors, this technique is now established as the standard solution in any production where PVC-powders are used.
If one machine shall be excluded from the process, just close the shut-off valve. The electrical interlock is automatically effected by the level indicators.
