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 …
Drying plays a critical role in the agglomeration process. When used prior to agglomeration, drying prepares material feedstock for agglomerate formation, and has a direct effect on how material will perform during agglomeration. Used after agglomeration, drying cures pellets into their final, strong form. In …
When it comes to drying bulk solids, rotary dryers are often the industrial drying equipment of choice. Their robust build, reliability, and aptitude for handling variation in feedstock makes them an ideal choice for efficiently drying bulk solids of nearly all types. When referring to …
Capable of causing costly damage to equipment, as well as process inefficiencies and unnecessary downtime, corrosion is a common problem faced when working with rotary dryers. This is particularly true of dryers that were not designed with corrosion in mind. Fortunately, there are several ways …
Drying potash is a vital aspect of processing the ore into a usable form for the fertilizer production process, as well as in finishing product coming off of the fertilizer production line. The following article highlights the basics of potash drying, including benefits, equipment, and …
While demand for frac sand is nowhere near where it was during the boom seen over a decade ago, the industry is seeing somewhat of a resurgence, putting rotary dryer services in high demand. In the 2010s, producers were looking to get their new plants …
Rotary dryers are essential to many bulk solids processing and handling operations, reducing the moisture content of both raw materials and finished products. About Rotary Dryers Rotary dryers use a tumbling action in combination with a drying air in order to efficiently dry materials. Most …
When it comes to thermal processing, confusion often arises in choosing between a rotary kiln and rotary dryer. Although these two types of equipment share similar thermal processing principles, they are used in very different applications: Rotary dryers are used for drawing moisture out of …
Many factors are taken into consideration when designing a rotary drum dryer that can both efficiently and effectively dry a material. Factors such as the material’s bulk density, heat sensitivity, particle size, and flowability, among others, all interact to influence how the material will behave …
Rotary dryers and rotary kilns share similar thermal processing functions, but each is intended for very different industrial applications. Rotary dryers operate at inlet temperatures between 600 and 1400ºF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other …
