The unique characteristics of potash can present challenges during processing, whether it is being processed via pelletization or compaction granulation. Potash, and many other salts, are hygroscopic, meaning they easily absorb and retain moisture from the environment. As a result, potash is prone to clumping …
Our photo this week highlights a pin mixer currently under production in FEECO’s Fabrication Facility. Pin mixers are industrial mixers used to condition, mix, micro-pelletize, and agglomerate material. They can be used a pre-cursor to a disc pelletizing or agglomeration drum set-up, or as a …
Coating drums are used throughout a number of industries to carry out particle coating applications. Commonly used after agglomerate processing, coating drums work by tumbling particles in a rotating drum and spraying them with the desired coating material. This may be to improve product handling, …
Smelting is a pyrometallurgical process that uses thermal processing techniques to purify copper through chemical reactions. And while most focus is given to the furnaces involved in this process, one piece of equipment has not only helped to increase the efficiency of copper smelting, but …
Coating plays a pivotal role in producing roofing granules that not only provide the desired aesthetic appearance, but that can also withstand constant exposure to the elements. Uniformly and consistently coating granules to spec, however, can be a challenge. One of the best ways to …
This week’s photo shows agglomerated fly ash. Fly ash is a process by-product resulting from fines rising with flue gases during the production of power in coal-fired power plants. Although fly ash has traditionally been landfilled, it has been discovered as a valuable additive in …
Rotary drums are used throughout a number of industries to carry out a range of different objectives, from conditioning to granulation (agglomeration), mixing, and coating. Part of their diverse applicability lies in the ability to customize their internals for a truly optimized processing solution. In …
Some limestone pelletizing operations use a pin mixer to condition the material prior to processing it on a disc pelletizer. While this step is not required, adding a pin mixer to a limestone pelletization process offers many benefits to the overall agglomeration operation at hand, …
As sulfide nickel ore deposits decline in both number and grade, many industry experts see upgrading low-grade laterite ores as an essential step in satiating rising nickel demand in the transition to a low-carbon economy. A combination of reduction roasting and magnetic separation has emerged …
This week’s photo shows a rotary drum gear before and after replacement. The gear on the left is exhibiting excessive wear and inadequate lubrication. This is an example of extreme wear, and was caused by tramp material entering the gear mesh. At right, the gear …
