Conveying, feeding, mixing, size reduction, sifting... Systems and components for the bulk materials processing industry Powder Processing Equipment and Systems

Over 115 years of expertise. Gericke bulk materials processing technology can be found throughout the world in many sectors including the food, chemical, pharmaceutical, plastics and construction materials industries. Experience Gericke was founded by Walter H. Gericke, Milling Engineer, in Zurich (Switzerland) in 1894. The company has been designing and manufacturing equipment and systems for modern bulk material processes and providing design and consultation services ever since. Customer proximity The head office of the Gericke Group is in Switzerland. We do however have subsidiaries in many...

Customer support during the planning, implementation and commissioning of a system is of great importance to Gericke. It is essential to achieve highest possible efficiency during production and to increase the cost-effectiveness of an investment to the upmost. Our processes undergo regular checking in accordance with the ISO 9001:2000 standard. Key components are developed and manufactured by Gericke.

Receiving and discharging (of raw materials)… Big bag emptying and filling station There are various options for the reliable filling, emptying and handling of big bags. Filling and discharge stations with integrated weigh feeders and conveying equipment transport the bags (once they have been filled) to the next stage of the process. Sack tipping and feeding station Ergonomically designed bag feeding with integrated sifting equipment, magnets and nibblers for deagglomeration of material. The integrated or centrally positioned filters ensure a clean and safe working environment. Dust-free infeed...

Conveying … Pressure vessel Gentle conveying prevents abrasion, increase of bulk density and disintegration of particles. Slow conveying speeds between 3-15 m/s of plugs of material and strands. Pulse-line system with automatic control of conveying air of up to 80 m3/h and conveying distances of up to 400 m. Distinctive features of pneumatic Lean phase conveying systems: - Concentration (μ): indicator showing loading efficiency in the pipework - Speed: stress on material being conveyed Medium phase cubes in relation to conveying speed - Suction or pressure: different types of process design in...

Feeding … Volumetric feeders The bulk material is metered volumetrically with a feeding helix or screw. Intromitters prevent the formation of bridges and ensure homogeneous conveying of the bulk solids into the feeding tool. Volumetric feeding The feed rate depends on the volume of product transported per time unit. Loss-in-weight feeders For continuous gravimetrically controlled loading of extruders, kneaders or continuous mixers. As a batch feeder for the weighing of products. The Easydos controller can be used as a flexible solution for all feeders and metering applications. The feed rate...
