GRANULE EXTRUDER (TOP FEED)
Granule Extruders with Top Feeding Unit are mostly used for granulating free flowing rigid flakes. Shred or ground dry plastics and washed and dried plastics can be granulated.
Pneumatic actuated valve is used between Hopper and Extruder’s screw to adjust feeding gap according to load of Extruder. Plastics to be granulated are transferred to screw by free flow. Hopper can be equipped with a motor-powered vertical agitator to prevent bridging in case of processing thin flakes. (such as thin walled bottles etc.)
Screw diameter, screw length / diameter ratio (L/D), degassing zone amount, melt filter type is designed according to type, form and contamination of input.
PTA hard face welding is applied on screw flights for extra protection against abrasion. Screw and barrel are hardened by nitration and induction. Bimetallic barrels produced by centrifugal casting are also available.
Thanks to speed-controlled Extruder Screw, constant pressure and high throughput is reached while processing plastics with different bulk density and MFI range.
Direct coupling connection of gearbox and main motor, ceramic insulated heaters and inverters lead to high energy efficiency.
Granule Extruders are controlled by intelligent PLC system and user-friendly touch screen. Receipt system allows saving parameters for different types of plastics and this allows fast and reliable parameter changing for different plastics. “Single Button” starting feature leads to simple operation for Granule Extruder.
