Rotary dryers play an increasingly important role as lithium producers work to meet rising demand for electric vehicles, energy storage, and electronics, pushing operations beyond simple extraction into the production of tightly specified, battery-grade chemicals. Across brine, hard-rock, and emerging clay projects, drying remains a …
The pyrolysis kiln looks to be an effective approach in recycling black mass – the powdery mixture of key battery minerals remaining after mechanical reduction of spent lithium-ion batteries (LIBs) – as the increasing adoption of LIBs in everything from cellphones to electric vehicles has …
The benefits of a preventive maintenance program are well documented – reduced downtime, lower maintenance costs, improved safety, and longer equipment service life, among others. And yet, many industrial facilities continue to rely on reactive maintenance strategies for their capital equipment, exposing them to unnecessary …
Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their jobs. Heat transfer is how heat moves from one source to …
Rotary drum shells form the basis of applications ranging from dryers, kilns, and coolers, to agglomerators, coating drums, and more. As one of the primary and most costly components of the equipment, maintaining the integrity of the shell through regular monitoring and repair is critical …
Rotary drums, used in applications ranging from drying and granulation to thermal processing, are subject to significant mechanical stresses over time. One of the most critical components of a rotary drum maintenance program involves maintaining proper drum alignment and structural integrity of the tire, or …
In rotary kiln engineering, dams are often an overlooked yet critical component in controlling material retention and thermal efficiency. These strategically placed internal structures help engineers fine-tune process performance, making them an essential part of kiln design—particularly when processing solids that require extended retention times …
As industries pursue cleaner operations and greater efficiency, many producers are asking whether their rotary kilns (and in some cases, dryers) should be powered by electricity instead of traditional fuels such as natural gas, oil, or diesel. While electrification offers compelling advantages, it also presents …
Rotary drums are central to countless industrial processes, and whether drying, heating, cooling, or granulating, their performance depends on precise alignment and structural integrity. One often-overlooked, yet critical, rotary drum maintenance task for ensuring both is tire reshimming. A small adjustment with a big impact, …
Rotary kilns are used in a variety of thermal processing applications, and depending on the material being processed and the process objectives, internal components are often employed to improve efficiency. One such component is the bed disturber, widely employed in indirect kilns. While not always …
