Screw Feeder

Description

Volumetric screw feeder dosing Palamatic

Weight or volume feeding for powders and granules - High precision

The screw feeder provides a steady and controlled feed of your bulk powders, typically from a temporary storage unit like a hopper, to your downstream process. The addition of load cells allows more accurate dosing and control of the production process.

Screw feeders range

4 standard models D10, D11, D12 and D13, with flow rates from 37 to 9,666 lbs/hr.

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

Models	D10	D11	D12	D13
Max theorical rates in lbs/hr	37 to 219	137 to 807	402 to 2,219	1,811 to 9,966

The Palamatic Process screw feeder can be configured on the manual dosing unit for pre-weighed micro-ingredients.
