Small Doses, in a Space That Will Not Take a Full Feeder
Cosben Engineering’s micro batch feeder is designed for applications where small quantities of material need to be dosed accurately and consistently. In many processes, especially where additives or minor ingredients are involved, even slight variations can affect the final product. A reliable precision dosing feeder helps maintain control at this critical stage.
Also referred to as a micro feeder or micro screw feeder, this system is built for compact installations where space is limited but accuracy still matters. It ensures smooth and controlled feeding of powders and granular materials without unnecessary complexity.
With a simple and practical design, the feeder offers stable performance for continuous operation while keeping maintenance requirements low. It works well as an additive dosing feeder in processes that require consistent, repeatable small-batch feeding.
