Bulk Material Feeders

In-Use Advantages

NBE dry bulk material feeders enable accurately measured introduction of material into processing operations. Regardless of material characteristics, NBE bulk material feeders deliver a consistent and repeatable feed of material, whether in continuous flow for pre-feed or feed applications, or in intermittent flow for batching applications. NBE bulk material feeders are driven by automatic control systems synchronized with upstream and downstream line operations to reduce material waste and ensure efficient bulk material processing.

Features & Integration Guide

Volumetric Bulk Material Feeders:
NBE volumetric bulk material feeders are designed to provide a constant flow of material, within a specified unit of time, into the process operation. This feeding method is most appropriate for applications where material characteristics are consistent, particularly in density, size, and moisture content. Single-screw feeders are available for free-flowing material; a twin-screw design is available for non-free flowing material.

Gravimetric Bulk Material Feeders:
NBE gravimetric bulk material feeders , also known as weighfeeders, are designed to provide a constant flow of material, based on the weight of material fed, within a specified unit of time. This feeding method is most appropriate for applications where material characteristics may vary; where long-term, accurate, and repeatable operation is necessary, and where dust control may be an issue.
