Depending on the circumstances, indirect fired rotary kilns can have many advantages over direct fired rotary kilns. One such advantage is when the required thermal processing is best done in an inert atmosphere. As an example, most carbonaceous solids will combust when at elevated temperatures …
In the thermal processing industry, rotary kilns are used to cause chemical reactions or state changes in varying materials. As discussed previously in Direct Fired Rotary Kilns vs. Indirect Fired Rotary Kilns: What’s the Difference, while direct fired rotary kilns and indirect fired rotary kilns …
Whether a rotary drum is being used as a dryer, kiln, cooler, or otherwise, it is often a key process component in a production setting. As a result, downtime for the rotary drum can have the potential to hold an entire operation on idle. For …
Biogas has been a popular topic of discussion lately, as the need for energy increases, and sources are being run dry. Sometimes referred to as swamp gas, landfill gas, or digester gas, biogas is generated from anaerobic digesters such as animal manure, sewage, and municipal …
Rotary kilns are used to process a wide variety of materials, causing a chemical reaction or phase change. Within the rotary kiln industry, there are two major subsets: direct-fired rotary kilns and indirect-fired rotary kilns. Both kinds of rotary kilns employ the same thermal processing …
Rotary dryers have been a part of the thermal processing industry for over a century, and have earned their reputation as the industrial drying workhorse. These robust industrial drying systems have become a staple in just about every industry requiring bulk solids to be dried, …
In addition to the many material characteristics that must be considered during the sizing and design stages of engineering a custom rotary dryer, there are also a few operating environment factors to consider as well. Atmosphere Considerations: Humidity Humid air is already moisture-laden, meaning that …
Rotary dryers are used across nearly every industry that requires the drying of bulk solids, be it for producing a product for consumer use, serving as an intermediary step in a larger process, or producing an industrial product that will maintain its integrity throughout its …
Several material characteristics must be included in the design of a rotary dryer that operates efficiently and reliably. In addition to a material’s specific heat, its heat transfer properties must also be taken into account during the dryer sizing and design process. Material Specifications: Heat …
Rotary dryers are the backbone of many industrial processes, ensuring bulk solids are properly and efficiently dried to produce a product ready for market or subsequent processing. The design and sizing of a rotary dryer is engineered around the characteristics of the material to be …
