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 …
Rotary dryers play a crucial role in catalyst manufacturing, where the drying step is essential for ensuring the final product meets precise standards. Though often overlooked, drying significantly influences key properties like uniformity, mechanical strength, and moisture content. This article explores the importance of the …
After decades of production, rotary kilns used for calcination in catalyst plants and manufacturing facilities are reaching the end of their service life. Producers looking to replace their aging calcination equipment are quick to order a duplicate system, but what many don’t realize is that …
A rotary drum, be it a dryer, cooler, agglomerator, or otherwise, is a major investment and integral part of many industrial processing systems. From drying and cooling bulk solids before storage, to agglomerating ore fines in a heap leaching operation, the rotary drum often serves …
