In the early 1980s, Kamengo led an extensive research program that uncovered key reasons why bins suffer from chronic plugging. The research also produced new technologies for handling difficult flowing materials.

Kamengo’s research demonstrated that equipment must be designed according to the stored material’s flow properties. A bulk material’s flow properties dictate the conditions the stored material requires to build a stable bridge or pipe and hang-up. Good bin and feeder design is about knowing what these conditions are, and designing your storage and feed equipment to deny the stored material these conditions. When interpreted correctly, material flow properties not only provide you invaluable guidance on minimum design requirements, but also allow you to compare the behaviour of your material with the behaviour of other, similar materials, for which working, proven storage and feed configurations exist.

There are five tools that Kamengo offers that lever the best of what material sciences has to say about designing for difficult flowing materials. These tools and our decade’s long experience of delivering reliable solutions is what differentiate us as a partner in your problem solving process.




Equipment to characterize the flow properties of fibrous and cohesive materials



Before you can apply material flow properties, you first need to determine what they are. The problem is that early equipment for characterizing material flow properties were designed for testing granules and fine powders. In the 1980’s Kamengo developed new testing equipment capable of handling stringy, fibrous and cohesive materials. This equipment allows us to reliably characterize and design for a wide range of difficult flowing materials, including fibrous and cohesive materials.





Design protocols to determine correct bin, feeder and chute geometry.



Kamengo has developed design protocols to correctly and reliably interpret a material’s flow properties to determine the correct bin, feeder and chute geometry required to promote reliable material flow. Correct equipment geometry will deny a stored material the conditions it needs to build the internal strength needed to form a stable bridge.





The Kamengo Feeder: Proven solution for handling difficult flowing bulk materials



A ground-breaking outcome of Kamengo’s research was the design of the Kamengo Feeder. The Kamengo Feeder resolves many of the shortcomings of conventional feeders that result in material plugging. With installations running 24/7 for more than 20 years, the Kamengo Feeder has proven that it is a reliable solution for handling difficult flowing materials.





The Kamengo Feeder: A design advantage



The flow properties of difficult flowing materials often demand a first-in, first-out discharge with material drawn out evenly from the entire bin opening. This scenario is very difficult to achieve with a conventional feeder, but is easily achieved with a Kamengo Feeder. Moreover, with a Kamengo Feeder, this scenario can be achieved in a variety of long and short storage configurations, ensuring that we are able to deliver an ideal storage configuration for your application.





Skilled design practice



Over the past 25 years, Kamengo has developed a design practice capable of tackling complex projects, including retrofits of storage and feed arrangements that suffer from plugging. Kamengo has the engineering capability to deliver complete packages of materials handling equipment including storage bins, feeders, chutes, structural work, and conveyors. We have delivered solutions for biomass, ore concentrates, fly and wet bottom ash, wood chips, pellets, and FGD gypsum.
