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, as well as kilns, coolers, and granulators, are essential to many bulk solids processing and handling operations, processing both raw materials and finished products to reach quality specifications. Understanding Rotary Equipment Component Architecture Whether they will be used as dryers, kilns, or otherwise, …
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 materialโs 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 1400ยบF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other …
Asphalt shingles are the leading choice for residential roofing in the United States. They are affordable, durable, low maintenance, versatile, and have proven effective in the roofing industry for almost 100 years. A large part of their effectiveness, however, lies in the the roofing granules …
Rotary dryer misalignment is oftentimes the result of improper base installation. Misalignment in the base will quickly spread through the rest of the drum, causing wear and damage to other drum components. In addition, misalignment can occur naturally over time as part of normal rotary …
Todayโs photo highlights a rotary dryer in FEECOโs Fabrication Facility. The drum was recently painted, and will soon be ready for shipment. This particular dryer features our direct drive option, the mechanism that causes the drum to rotate. It eliminates the need for a girth …
Flights, also known as โfinsโ or โmaterial lifters,โ are commonly used in both rotary dryers and coolers to maximize heat transfer between the material and the drying or cooling air. Affixed to the interior of the drum, they pick up the material as the drum …
Though far less common than the need to dry or thermally treat a bulk solid material, some process settings call for preheating a material in preparation of downstream processing. In achieving this objective and meeting the high tonnages associated with bulk solids processing, rotary dryers …
