Activated carbon, sometimes called activated charcoal, is a unique adsorbent prized for its extremely porous structure that allows it to effectively capture and hold materials. Widely used throughout a number of industries to remove undesirable components from liquids or gases, activated carbon can be applied …
Bed disturbers are used in both direct and indirect-fired rotary kilns to promote uniform heating of the material. The bed of material should roll, not slide, throughout the kiln in order to expose fresh material to the process. This rolling action allows for even heat …
Rotary kilns have become an integral processing device throughout many industries. Capable of facilitating chemical reactions and phase changes, they are applied to a diverse range of applications, from metal recovery, to specialty chemical production, and carbon activation, to name a few. In fact, the …
For many years, rotary kilns have been used across various industries to drive chemical reactions by thermal processing. Rotary kilns have become very established in fields such as cement, lime, and minerals. Because these thermal processing tools have been used almost exclusively in these industries, …
Electronic waste, or e-waste, is continuing to capture global attention thanks to a litany of issues associated with the waste, ranging from environmental hazards to humanitarian concerns. As growing amounts of the waste add to fears of a looming crisis, efforts to recover valuable materials …
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 …
