Low Rate and Lab Feeders


Orbetron's AS30, AT16 feeders are specially designed to feed free-flowing products as well as poor-flowing powders at very low rates. The removable feed hopper makes it ideal for applications that require quick material changes. To make a material change, just remove the existing hopper and replace it with a new clean hopper. The removable feed hopper can also be used as a storage container, completely eliminating cleaning and the possibility of product contamination.

These include a single screw hopper to feed free-flowing products, twin screw with horizontal agitator to feed the most difficult products.

Orbetron offers two types of gear boxes (oil filled or dry) to give processors the best solutions in low rate feeding. 

The feeder can be easily integrated with gravimetric or volumetric controls, as well as installed separately or in a production line with multiple feeding devices.

Orbetrron offers the widest gear ranges for single and twin screw lab or low rate feeders. We offer as standard ratios the following;

6:1, 36:1 93:1 150:1 308:1 to give Orbetron the ability to feed the low rates necessary for your processing requirements.
