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 …
The frac sand dryer has become a critical component in meeting todayโs growing demand for high-quality proppants used in hydraulic fracturing. As rig counts rebound and the volume of sand used per well continues to climb, the global frac sand market reached a valuation of …
Rotary kilns are widely used across industries that require precise, high-temperature heating of materials, such as mineral processing, chemical production, and waste management. Understanding the differences between direct and indirect-fired designs is critical for engineers seeking the right equipment for specific thermal processing requirements; while …
Rotary dryers have a long history in many industries, but perhaps none more than in the fertilizer industry, where they are an essential component in processing minerals for fertilizers at mine sites, and for producing many of the fertilizer products on the market today. Rotary …
Fluid bed dryers are one of the most popular types of industrial dryers, and for good reason: their high rate of heat transfer, paired with their wide applicability and small footprint, makes them favorable in a range of different production settings. Acquiring a fluid bed …
Recent advancements have made rotary kiln alignment methods faster and more effective than ever. Misalignment is one of the most common (and most treatable) causes of rotary kiln damage. Alignment touches all components of a rotary kiln, with misalignment promoting wear on all parts. In …
Fluid bed dryers offer an effective approach to reducing moisture in bulk solids, leveraging fluidization to achieve uniform drying and high efficiency. However, achieving optimal performance in these systems requires careful consideration of design and operation. Issues such as poor fluidization, excessive fine particle loss, …
In engineering a fluid bed dryer, one of the most critical aspects to consider is the fluidization regime, or what can be considered the pattern of material fluidization. With several flow regimes possible and each having a significant impact on the efficiency, rate, and consistency …
A mass and energy balance, also known as a heat and mass balance (HMB), is a critical step in the rotary kiln design process. Unbeknownst to many, however, it can provide significant value beyond the design process as well, helping buyers to estimate operating costs, …
