1FEEDING AND DOSING SOLUTIONS FOR BULK
MATERIALS FROM GERICKEAccurate and reliable feeding of bulk materials is at the heart of many processes. Whether feeding into a
continuous mixer, an extruder, mills, reactor, rotary kiln or any other process, accurate metering of bulk
solids is key to process control and ensures highest product quality standards.

Fully implemented with your automation

Volumetric Feeding

The Gericke Controllers simplify the configuration of yourprocess tasks and integrate easily with any automation
concept. You benefit from the combined experience of Gerickein machine design and process and automation competence!

High-precision volumetric feeding of bulk materials requires awell-designed feeder with an optimised geometry of feeding chamber andfeeding screw. From sticky, cohesive powders to flushing powders –Gericke volumetric feeders are perfectly adapted to deal with even themost challenging bulk materials.

Process Integration

Gravimetric Feeding

In many installations, feeders operate closely interconnectedwith up- and downstream equipment. Process integration as
well as setup conditions, thus play an essential role, especiallyfor the performance of gravimetric feeders. Based on ourextensive experience in powder handling our engineersconsider these factors already during the design andengineering phase to maximize the performance ofGericke feeders.

Gravimetric feeding combines volumetric feeding, advanced weighing
technology and control. It delivers either a requested quantity as a batch(e.g. kg) or a constant mass flow (e.g. kg/h) continuously over time.
In order to achieve a controlled feed rate the weight loss is
continuously monitored by high-accuracy load cells and the speedof the feeding tool is adjusted accordingly. Besides an optimisedmechanical design this also requires sophisticated load measurement
and control technologies, which are an integral part of all Gericke
gravimetric feeders.

Why volumetric feeding solutions from Gericke?
• Highly precise metering tools, proven in many industries• Suitable even for the most difficult to feed products• Easy to clean where needed

Gericke volumetric feeders combine a precise volumetric material flow and a high degree of flexibility. Often, they arethe most economic choice for applications which do not require the exceptional accuracy of loss-in-weight feeders.

FEEDOS Series
The FEEDOS Series combines high-accuracy
volumetric screw feeding with a modular andcompact design that allows for quick disassemblyand easy cleaning. Its optimised geometry
guarantees stable and reliable product flow - evenfor bulk materials which are difficult to handle, suchas cohesive or easily fluidisable powders.
GDU Series
Gericke’s GDU Series combines high-precision
volumetric feeding with excellent residue removal.
GDU feeders cover a broad range of applications innumerous industries due to their versatility. Whether
it’s about feeding free-flowing pellets or fine,cohesive powders – GDU feeders have proven
their capabilities in thousands of installations.
GAC Series
The GAC Series features a unique design withintromitter and feeding screw being concentricallyaligned. Thus, even powders with the mostchallenging flow properties can be fed accuratelyand reliably. GAC feeders are especially suitedfor heavy-duty applications, for example, in thechemical and minerals industries.

Vibro Feeders
Vibro feeders use a combination of vibration andgravity to feed material. They are perfectly suited forlight, coarse and fragile products such as tablets,dragees, granulates and flakes. They are easy toclean, and have no rotating parts.
Rotary Valves
A rotary valve consists of a cellular wheel withtypically 8 - 10 pockets. This wheel rotates ina housing, feeding the bulk material.
They are a common product in many powder
handling applications, e.g. for feeding into apneumatic conveying line or metering below
a big bag station.

GERICKE GRAVIMETRIC FEEDERS – DESIGNEDFOR HIGHEST ACCURACY
Gericke’s gravimetric feeders combine advanced volumetric feeders with precise load detection and sophisticatedcontrols to guarantee the highest accuracy for all loss-in-weight applications. Special executions of our loss-inweight feeders are available which consider the demands of the food, chemical and pharmaceutical industry.

Why gravimetric feeding solutions from Gericke?
• Save money with accurate feeding!
• Different weighing principles always give you the perfect fit• Perfect integration with your process and automation

WEIGHING SYSTEMS WITH DIRECT LOAD
MEASUREMENT
A universal and compact weighing and feeding design does notneed to come at the cost of reduced accuracy. Gericke’s loss-inweight feeders with direct load measurement present the mosteconomic and efficient way to gravimetrically feed bulk materials.

PLATFORM-BASED WEIGHING SYSTEMS WITH
DIRECT LOAD MEASUREMENT
Where high accuracy meets low feeding rates: In platform-based
systems, the feeder is mounted on a high resolution weighing
platform. The compact systems are easy to clean and built forindustrial environments. The main applications are in the foodand pharma industries, but can be adapted to any application
where highest accuracy is a must.

HYBRID WEIGHING SYSTEMS WITH TARECOMPENSATED LOAD MEASUREMENT
Gericke’s gravimetric feeders with a tare-compensated weighing
system are perfectly suited for applications where the emphasis isput on both high accuracy and exceptional robustness.
Because the dead load of the feeder is mechanically compensated,
the whole load cell range is available for measuring the weight ofthe bulk material only. Due to our unique spring-damper system,
vibrations are filtered before they even reach the load cell. Thus,
Gericke’s hybrid loss-in-weight feeders are especially suited tofeeding bulk materials with a low bulk density in challenging
environments.

Continuous Manufacturing of oral solid dosage pharmaceutical products
Our modular Gericke Formulation Skid GF Scombines high precision loss-in-weight feeders with ascientifically designed compact blender and integrated PAT solutions. The feeders use single or double screw feeding
tools, depending on the application.
Gericke GFS continuous mixing process technologies are ideally suited to the new era of efficient solid dose
pharmaceutical manufacturing. Our systems are fully developed, and in use at various sites and have been
approved by customers and the FDA.
