Introduction

The patented Circle Feeder™ (Mass Flow Feeder), manufactured by Yoshikawa Corporation of Japan, is a unique type of table feeder that accurately meters/discharges poorly flowing materials from bins or hoppers. Flat, slowly rotating vanes (1) cause radial flow of material under an adjustable annular ring (2). Peripheral rotary vanes (3) convey this material toward one or more discharge ports (4).

Benefits

The Circle Feeder's large inlet easily exceeds most material's critical arching diameter. This, along with well distributed mass flow around the circumference, eliminates the formation of a stable arch and the resulting flow disruption.

In addition, new installations require less height because of the Circle Feeder's low profile and large inlet diameter, which reduces silo/hopper cone height. In some cases, the cone is totally eliminated.

The Circle Feeder's simple design and slow rotational speed assure quiet operation and low maintenance.
