Feeding & Batching

Designing the best volumetric feed solution for your material is the basis for any continuous or batch process. Utilizing screw, vibratory, belt, bucket, or rotary feed devices to best meet the application, precision feeding and metering has become a core competency for Spec’s custom systems.
