FEATURES of Screw Feeder Converyor

• Evenly mix different materials and effectively avoid material stratification during conveying process
• Motor-driven screw ensures low noise level in operation
• Fully closed conveying line, effectively avoid material contamination in the conveying process
• Stainless steel made screw, easy for installation and maintenance
• Reverse phase protector is pre-installed to avoid that the motor is incapable of conveying materials because of motor reversal
• The length of conveying pipeline can be determined by customer’s needs

FUNCTIONAL SCHEME of Screw Feeder Converyor

The screw feeder is mainly used with extruders of various specifications to automatically convey plastic materials from storage tank to the hopper. It achieves the automatic feeding through the circulation controlled by material level sensor. It features stable function, labor saving, safe and reliable.

PARAMETERS of Screw Feeder Converyor

We reserve the right to change parameters without prior notice.

Notes:
(1) Conveying capacity is based on pellet material of 0.65kg/L in bulk density and 3-5mm in diameter.
(2) Special requirements for “OSF” can be customized.
(3) Power: 3ф, 230/400/460/575VAC, 50/60Hz.

Applications of Screw Feeder Converyor



OSF series screw feeder is good for plastic flakes or some other materials with very light bulk density which is not easy to fall off in Hopper receivers of vacuum auto loaders. It occupies more space than auto loader, and the convey distance is less than auto loader. So OSF screw feeder is always applied in circustances like short distance conveying with large capcity (specially in plastic recycled materias like PET flakes).

In the above application, there are 3 pcs of OSF screw feeders, the 1st one load PET flakes to a OHM horizontal mixer dryer for pre-crystallizing & drying, the 2nd one load the crystallized PET flakes to the 1st OHD-O hopper dryer for drying, the 3rd one load the PET flakes from the 1st hopper dryer to the 2nd hopper dryer (mounted directly at the feedport of extruder, applied with ORD-H dehumidifier) for production.
