In regards to rotary dryer use, retention time is the duration of time that a material must remain in the dryer to achieve the desired end-product characteristics. Retention time is an important consideration to the dryer design, and is defined by looking at the specific …
Rotary coolers offer an effective approach to cooling bulk solids exiting a rotary kiln or dryer, allowing material to safely move on to packaging, handling, or transport. These diverse industrial coolers are available in two primary configurations: convective (direct) and indirect water deluge, each with …
The performance of a rotary dryer is vital to maximizing process efficiency and capacity in any industrial process setting. While a well-designed dryer will yield few problems of its own, various factors can cause the performance of the overall drying operation to degrade. Process audits …
Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results. The retention time required for a given application is determined through balancing the necessary process parameters – …
This week’s highlighted resource is a Slideshare presentation on rotary dryers in the frac sand industry. This Slideshare presentation provides an overview on how rotary dryers are used in the frac sand industry, including why rotary dryers are chosen over fluid bed dryers and common …
Activated carbon, sometimes called activated charcoal, is a unique adsorbent prized for its extremely porous structure that allows it to effectively capture and hold materials. Widely used throughout a number of industries to remove undesirable components from liquids or gases, activated carbon can be applied …
Bed disturbers are used in both direct and indirect-fired rotary kilns to promote uniform heating of the material. The bed of material should roll, not slide, throughout the kiln in order to expose fresh material to the process. This rolling action allows for even heat …
Rotary kilns have become an integral processing device throughout many industries. Capable of facilitating chemical reactions and phase changes, they are applied to a diverse range of applications, from metal recovery, to specialty chemical production, and carbon activation, to name a few. In fact, the …
This week’s highlighted resource is a Slideshare presentation on rotary dryer sizing and design. Rotary Dryer Sizing and Design provides an overview on the complex process behind sizing and designing a rotary dryer for a given application. Material properties that affect dryer design are also …
For many years, rotary kilns have been used across various industries to drive chemical reactions by thermal processing. Rotary kilns have become very established in fields such as cement, lime, and minerals. Because these thermal processing tools have been used almost exclusively in these industries, …
