PNC Posimetric Feeder

Introducing POSIFLOW™ Feeders by Pennsylvania Crusher Brand – a groundbreaking positive displacement feeder that revolutionizes feeding technology. These feeders offer unparalleled reliability, maintaining precise and constant feed rates with only a single moving part. Notably, they eliminate fugitive dust, enhancing safety in power plants and cement plants. POSIFLOW™ handles a wide range of bulk solid materials, from wet and dry to lumpy, sticky, abrasive, or granular, without feed rate errors due to moisture variations. With virtually no plugging, minimal downtime, and low maintenance requirements, this feeder simplifies operations and provides capacities from 3 to 1800 TPH. It’s a game-changer in uniform feeding, dust elimination, and trouble-free operation. POSIFLOW™ – where innovation meets efficiency!

Type L Disc Liners: Your Answer to Simplified Maintenance and Extended Equipment Life!
Our new Type L Disc liners for POSIFLOW™ feeders are designed to extend wear life and simplify rotor rebuilds. These liners tackle excessive wear on the rotor disc’s outside diameter, especially in abrasive material operations. With enhanced durability, they provide superior protection, reduce downtime, and cut maintenance complexities. Precisely aligned and securely fastened, they ensure long-term performance, slashing wear-part costs. Upgrade to Type L liners for improved POSIFLOW™ feeder performance and easier maintenance.
