With a single moving part, the Posimetric Feeder offers the customer a truly elegant solution to bulk feeding problems, by providing exceptional

Accuracy. Compared with a belt, paddle or vibratory feeder, which cannot assure positive displacement of feed material, the Posimetric responds linearly to a change in demand (that is, a 5% increase in desired feed results in a 5% increase in actual feed!). This is accomplished with a one-time calibration.

Flexibility. The Posimetric will feed the most difficult solids- even those that are extremely sticky or abrasive. There are no flights or vanes to adhere to the feed material, so the feeder is self-cleaning.

Near-Zero Maintenance. Due to extremely slow operating speeds, even the most abrasive materials will not cause wear. No existing feeder component has ever been replaced (or shown any wear, for that matter!)

Reliability. Since Posimetric Feeder components cannot fail catastrophically, and the feeder is virtually incapable of plugging, feed-related process interruptions are eliminated.

Bulk solid materials will bridge over a particular span. This universal fact, which is to blame for many feed disruptions, is actually the operating principle behind the Posimetric Feeder. Material simply bridges between two disks, and moves with them as the machine turns. When the material finds an opening, it simply falls out into the downstream process. This bridging, or lock-up, means that the feed material does not move relative to the rotating disks, so abrasion is eliminated.

PCC approaches each application with an engineered solution- verifying the applicability of a particular feeder to a particular material, and for the customer's particular plant process.
