Product information
Screw feeders for optimum performance and dosing accuracy:
SD 25 Servo, SD 50 Servo and SD 80 Servo
Screw feeders for accurate and economical volumetric dosing of powdered to fine-grained products. In accordance with the Finished Goods Packaging Regulations (FVP).
When powdered or fine-grained products need to be filled particularly gently and dust-free, the screw feeders impress with their dosing accuracy and dosing rates of up to 160 dosages/minute in the volumetric range from 0.5 to 20,000 cm3.
This also applies to light and difficult-to-flow, dusty and sticky products such as spices, coffee, children's food, chemical-pharmaceutical powders and dusts.
The screw feeder feeder is used as a unit for direct container filling. And it is also synchronised with the puff bag machine.
Due to the high dosing accuracy, there are no deviations in the stacking density, overfilling is avoided and product (filling material) is saved.
Thanks to servo drives and modern electronics, infinitely variable and precise screw rotation is possible.
Reduced overfilling saves product costs with a standard deviation of +/- 0.5 per cent.
As a result, the return on investment is quick, usually within one year.
