A pugmill mixer, or paddle mixer, is a horizontal, continuous industrial mixer used in a variety of applications for processing bulk solids to achieve a range of objectives. These rugged mixing units are highly flexible and have become an essential tool in many processes. They …
This week’s photo illustrates the build-up, or sticking of material in a granulation drum. Granulation drums, used in the fertilizer industry, can be prone to build-up on the interior of the drum for a couple of different reasons. Often times, the material or binder can …
Catalysts are an invaluable tool in many industrial processes, helping to facilitate reactions between materials. They are so important in fact, that some experts estimate they are responsible for 85-90% of products in the chemical industry.¹ As the role of catalysts in industry continues to …
Micro-pelletizing can be carried out in a pin mixer, or in a pin mixer/disc pelletizer (pan granulator) combination. Pin mixers alone often provide efficient results when full-scale pelletizing is not necessary, or when only smaller pellets or conditioning is needed. To begin, the pin mixer …
Coal, a combustible, sedimentary rock, has been used for centuries as a reliable energy source. Despite growing renewable energy sources, coal is still the backbone of the world’s energy grid, providing the electricity we need to turn on lights, heat our homes, and cook our …
This week’s photo shows the interior of a rotary kiln, as a technician works to remove build-up on the refractory. Build-up can sometimes occur in an over-temperature condition which causes product to melt and become sticky. A primary design requirement with all rotary kilns is …
Gypsum, or hydrous calcium sulfate, is a crucial mineral in the production of everything from wallboard to cement and even many consumer products, surrounding us throughout our daily lives. United States gypsum production was at an estimated 20 million metric tons (Mt) of crude gypsum …
A sieve analysis measures particle size distribution, and more specifically, what percentage of on-size, over-size and under-size pellets are produced from the agglomeration process. The analysis is an important part of agglomerate process and product development, as it confirms whether or not the agglomeration process …
As the world continues to move away from fossil fuels, pyrolysis is becoming an increasingly important tool, helping to create a more circular economy by opening up opportunities in the production of alternative fuels from a variety of wastes. The rotary pyrolysis kiln is chosen …
FEECO offers a selection of bucket styles for both centrifugal and continuous bucket elevators, to accommodate the demands of varying materials. We offer two centrifugal bucket styles: style AA and style AC. Both options feature a reinforced lip around the leading edge to avoid distortion …
