Pelletizing is a non-pressure (tumble growth) agglomeration method whereby material fines are processed into pellets. It is used throughout a number of industries to transform difficult to handle powders and fines into a more easily handled, and valuable product. Pelletization involves the tumbling of material …
The bucket elevator serves as a key piece of equipment in vertically transporting material throughout a facility, whether it is a mine site or production plant. The selection of a well-built elevator often means the difference between an operation that runs smoothly and reliably, and …
This week’s photo shows the solid cylinders used to perform compression strength tests in the FEECO lab. Compression strength tests look at how an agglomerated material behaves under stress as a whole, as opposed to a single pellet. Lab technicians use a controlled product amount …
The value of gypsum pellets as part of an integrated systems approach to soil management has received increased attention and recognition over the last few decades. As a result, more and more questions have come up regarding gypsum processing equipment and how to effectively manufacture …
When it comes to drying material exiting a centrifuge, rotary dryers provide a reliable and consistent drying solution. Centrifuges are a critical and growing asset in modern industrial processing, allowing processors to separate solids from liquids in the pursuit of a wide range of production …
The circumference of the inside diameter of a rotary drum tire is larger than the circumference of the outside diameter of the shell, and therefore the tire will not make a complete revolution at the same time as the shell. This difference per revolution between …
Throughout the country and around the world, the coronavirus has upended every aspect of our lives, both at home and at work. While the crisis has shut down many industrial processing operations and changed others indefinitely, one thing that hasn’t changed is the need for …
Australia, a nation that has previously relied solely on imports of potassium, is quickly becoming a hotbed for potash production, particularly when it comes to the high-value MOP alternative, SOP (sulfate of potash). SOP exhibits characteristics that make it especially suitable for many Australian soils …
This week’s photo shows a rotary kiln’s leaf seals. The set-up consists of a series of overlapping spring steel plates that are attached to the housing, and ride on the rotating shell. Rotary kilns run at a higher temperature than the ambient air, thus any …
Variable Frequency Drives, or VFDs, are not a new technology, but only in recent decades have advancements in the field lowered many of the barriers associated with widespread VFD use, allowing their application in a range of settings. A recent market study anticipates that the …
