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 …
Many factors are taken into consideration when designing a rotary kiln. Each affects the ability to produce a desired chemical reaction/phase change in an efficient manner. Characteristics such as bulk density, specific heat, and flowability, among others, all interact to influence how the material will …
Limestone drying, typically carried out in rotary dryers, is utilized throughout this industrial mineral’s lifecycle, from quarrying to finished product. The following explores why drying is essential for quality limestone, its role in production, key considerations, and the importance of testing and equipment design for …
Rotary kilns are used across a number of industries to cause a chemical reaction or phase change in a material. This high-temperature thermal treatment can be used to carry out a variety of different objectives, from catalyst activation to aluminum decoating. The number of applications …
