The principle of deceleration of extruder production line

Extruded by the high-speed rotation of the extruder is naturally very good, but if it is only rotated at a high speed, it will cause some inconvenience to the material. At this time, it needs to be decelerated. So what is the deceleration principle of the extruder production line?

The plastics that can be extruded by an extruder line are thermoplastics that melt when heated and solidify again when cooled. Where does the heat to melt plastic come from. Feed preheat and barrel/mold heaters may play a role and are very important at start-up . However, the motor input energy ( frictional heat generated in the barrel as the motor turns the screw against the resistance of the viscous melt ) is an important heat source for all plastics except small systems, low speed screws, high melt temperature plastics and extrusion coating applications . Extruder As with all other operations, it is important to realize that the barrel heater is not the main heat source in the operation and thus has less of an effect on extrusion than we might expect. Back barrel temperature may still be important as it affects the galling or solids conveyance rate in the feed.

The deceleration of the extruder production line is changed in principle, except for the application of heat source, small system, low speed screw, high melt temperature plastic and extrusion coating, so that the extruded material is also very valuable.
