Description
volumetric screw feeder dosing
ATEX certification Palamatic Process

Weight or volume feeding for powders and granules

The screw feeders provide a steady flow, progressive and controlled your bulk powders retained in a hopper. The addition of load cells allows more accurate dosing and control of the production process.

Screw feeder range

 

 

4 standard models D10, D11, D12 and D13, with flow rates from 24 to 6,458 liters/h.

Palamatic Process powder feeders enable very high precision dosing of all bulk and raw materials with absolute safety.
