Rotary dryers and kilns are an integral part of the many industrial processes that shape our world. From fertilizer and chemical production, to ore beneficiation and even consumer products, these rotary drums provide a reliable, high-capacity setting for accomplishing a number of necessary objectives when …
The agglomeration drum occupies a critical position in the heap leach flowsheet, but rarely receives the operational attention commanded by the leach pad itself. Yet, when the agglomerator goes down, the entire operation can grind to a halt. With copper demand projected to outpace supply …
As demand for lithium continues to surge, the rising use of novel lithium sources, paired with the growing need to maximize process efficiency and the push for a circular economy, are all driving research and development work around extracting and recovering lithium. Findings from Grand …
Rotary drum alignment is a critical factor in maintaining the long-term performance and reliability of industrial rotary equipment—whether it’s a dryer, kiln, cooler, or agglomerator. Misalignment is one of the most common and potentially damaging issues encountered in drum operation. And while it may begin …
The tire mounting assembly on a rotary drum, whether a dryer, cooler, kiln, or otherwise, goes far beyond a mechanical interface; it ensures proper drum shell support, minimizes wear, and safeguards the equipment’s long-term service life. Over the past several decades, mounting technology has evolved, …
Agglomeration is emerging as a valuable complement to flotation in modern spodumene processing operations. As lithium demand drives the development of lower-grade and more complex deposits, the finer concentrate produced from flotation streams can challenge downstream calcination. The conversion of α-spodumene to β-spodumene requires consistent …
Conditioning is a term used frequently in the field of bulk solids processing to describe a wide range of material treatments, be it for a raw material, a byproduct, or a finished product. Conditioning is an important component in the processing of bulk solids, allowing …
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 …
As global demand for metals increases and high-grade ore sources deplete, mining companies are turning to technologies like heap leaching to efficiently recover valuable metals from low-grade ores. NAUE, a group specializing in geosynthetic liners, assesses that over 30% of copper and gold produced each …
The flow properties of a bulk solid can have a significant impact on process efficiency and the success of the end product. And while bins, hoppers, and the like are often designed to minimize such issues, agglomeration can be a valuable tool in improving the …
