Gently feed free-flowing granular media

| By Chemical Engineering


The K-ML-BSP-150-S Bulk Solids Pump (BSP) feeder (photo) provides gentle feeding of free-flowing granular materials without using screws, augers, belts or vibratory trays to convey the material. Instead, it utilizes positive-displacement action to feed free-flowing materials, offering uniform discharge, consistent volume and gentle handling. The BSP feeder has vertical rotating discs that create feeding ducts. Material moves smoothly from the storage hopper to discharge outlet through a “product lockup zone,” achieving linear mass flow. With no pockets or screws and only one moving part, the feeder is cleaned quickly, making it ideal for applications with frequent material changes. The BSP-150-S feeds at rates from 1.2 to 237 ft3 /h using five feeding discs to create four feeding ducts. It features a stainless-steel feeder body and uses a stepper motor. Two additional models are available for smaller feed rates. — Coperion GmbH, Stuttgart, Germany
