This week’s highlighted resource is a Slideshare presentation on rotary dryer sizing and design. The Rotary Dryer Sizing and Design slide deck is a great introduction to the complex process of designing a custom rotary dryer for any industry. Material characteristics that affect design, processing Continue reading →
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. The Asphalt Roofing Manufacturers Association estimates that 4 out of 5 homes are Continue reading →
Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial Continue reading →
This week’s highlighted resource is a web page on spent carbon reactivation. Activated carbon is increasingly becoming more popular as an adsorbent in many applications. One benefit to this amazing adsorbent is its ability to be reactivated and reused. This page covers the process of Continue reading →
Direct and indirect-fired rotary dryers are used in a variety of industrial settings to dry bulk solids. While the two are both comprised of a rotating drum and function to reduce a material’s moisture, several differences between direct and indirect dryers exist: Operation: direct-fired dryers Continue reading →
Rotary dryer shells can be constructed from a variety of materials, including: Carbon steel Stainless steel Hastelloy Inconel And other alloys Dryer shells can also be tailored in many ways, depending on the material and process requirements of the customer. For example, shell thickness can Continue reading →
With applications in everything from energy, infrastructure, and aerospace, to automotive, packaging, and more, aluminum has become a cornerstone of modern society. Aluminum’s widespread use might infer ease of accessibility, but such is not the case; aluminum is not found freely in nature, requiring the Continue reading →
Today’s photo highlights a rotary dryer in FEECO’s 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 Continue reading →
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 Continue reading →
When working with a rotary dryer or kiln, the sealing mechanism is a critical component in the overall performance of the unit. Sealing mechanisms create a seal between the rotating drum and the stationary housing, preventing air or process gas from leaking into the system. Continue reading →
