Is there any "pre" equipment that I can use to feed a 40 lbs brick/block of polymer into an extruder? Or is there an extruder with an openning that can handle handle a block of polymer? The polymer is high molecular weight and although it can be melted it would take some time.

How about chopping it into smaller chunks,then feeding to a granulator, then a micro-pulverizer. Rigid PVC
(pipe,siding,window profiles) regrind is reduced this way then fed back to the extruder.

Some rubber extruders have a large opening and screws that are designed to chew away at chunks.

Typically a grinder or shredder isa used for size reduction.
