Screw conveyor flights

Apr 04, 2017· The outer dia of flight is 27 on four turns and then ending at 40 on the last turn The pitch is 2143 mm I have tried a lot to fabricate it but cannot control the pitch or at times where the two "washers" meet (I am joining washers with the cuts (degree) and then joining them to get the screw...

COST OF BARREL AND SCREW WEAR

barrel As the amount of wear increases, the screw OD gets smaller and the barrel ID gets larger creating more clearance between the screw flights and the barrel While operating the extruder in this condition, the increased clearance allows plastic to pass over the flights of the screw instead of continuing forward...
