The continuous production of defect-free profiles with plastic extrusion requires precise technology. The extrusion process creates large axial forces on extruder screws that can damage components ...

This transparent view of a parallel twin-screw extruder illustrates the structure of the basic hardware that accomplishes compounding and end product extrusion in one step without subjecting the ...

Planet Earth is spinning at a rate of 0.0007 rpm. Easy to calculate: One revolution per day, divided by 24 to get revs/hr and then by 60 to get revs/min = rpm. As for linear speed, it depends on where ...

A twin-screw extruder can be used as a continuous wet granulator or as a continuous mixer for a wet gelatin mass. Twin-screw extruders, which have found commercial use in making amorphous ...

The screw conveyor has an extensive history. Archimedes (ca. 212 BC) invented the first screw conveyor, and his design is still used today for irrigation and grain transfer. Screw conveyors became ...
