Powder Processing Equipment and Systems Precision Feeders High accuracy feeding solutions for industrial processes Volumetric Feeders for bulk materials

Feeding – At the centre of total process control Proven designs with thousands of running applications. Gericke volumetric feeders are designed for throughputs from 0.05 to 50,000 litres per hour for most dry solids and liquid applications. Gericke’s range of feeders are based upon a robust modular design which are used in almost all processing applications including: - Chemical - Foods - Pharmaceutical - Construction Minerals - Plastics - Detergents Controlled feed into a Gericke continuous mixer Gericke – Feeding of bulk material since 1894. Gericke offer cost effective feeding solutions...

Modular feeding equipment – designed for process flexibility Volumetric feeding The feed rate is measured by volume against time. A reliable volumetric device is essential for a high accuracy gravimetric weigh feeder. ccurate metering of bulk solids is achieved using a spiral helix, rotary valve, rotating agitator, vibrating tray or cylindrical stator. Even in the volumetric mode, the metering rate remains constant under the condition of a repeatable fill level within of the selected feeding tool and an even bulk density of the powder. Gravimetric Feeding The feedrate or batch weight is...
