SAS 1SF - Twin Screw Feeder Assy & Control - APRIL 2020
TECHNICAL SPECIFICATIONS
The D series screw feeders are equipped with a double extracting screw, they guarantee
a homogeneous material flow, high precision and dosing regularity thanks also to the
screws that are machine made for a perfect coupling.
The D series twin screw feeders are designed for the dosing of powdered material and
synthetic fibres. They are available both on volumetric and gravimetric version with an
electronic loading cell weighting system that guarantees high precision and reliability.
They are used in their different configurations in all industrial fields, from concrete to
chemistry, from food to pharmaceutical industry.
The different configurations make them suitable for the use of materials that have very
different granulometry and fluency.
They are available also in configuration for ATEX areas.
A screw feeder makes the function to unload a theoretically constant material quantity on
each turn. This behaviour allows to make a specific load both on the granulometric and
volumetric version. It is expressed in dm³/h and the value is determined by the following
factors:
- Dosing screw rotating speed.
- Dosing screw pitch and diameter length.
- Used product specific weight.
