The frac sand dryer has become a critical component in meeting today’s 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 …
Refractory is specific to direct-fired rotary kilns, insulating and protecting the shell of the drum from high internal temperatures; they also function to maintain heat retention. Many types of refractory exist, with the most common options being brick or castable. Brick is typically used for …
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, …
As the role of catalysts in industry continues to grow, catalyst manufacturing research and development continues to rise. In this effort, the FEECO Innovation Center serves as a critical testing environment for producers looking to improve existing products or develop new ones. The following looks …
