Recovering oil prices have again made the extraction of oil and natural gas from shale formations profitable, prompting another surge in activity around recovering hydrocarbons via hydraulic fracturing. This has created a subsequent increase in the need for sand dryers, particularly as companies look to …
The frac sand industry continues to experience rising demand as drillers pump more of the proppant sand down wells than ever before. Where that sand is coming from, however, is changing; hydraulic frackers are looking to localized supplies of frac sand in an effort to …
Not unlike other boom and bust industries, the frac sand industry has been a turbulent one in recent years, with oil prices crashing and recovering, but industry experts are anticipating the continuation of a positive trend for the upcoming years. A new study by the …
Disparate materials can often clump together, or stick to the interior of the rotary dryer during the industrial drying process. This is referred to as unwanted agglomeration, or caking. Caking can occur for many reasons, but most often is the result of material characteristics that foster …
This week’s highlighted resource is a project profile for a sand dryer used in the frac sand industry. The frac sand industry is again booming as drillers pump more of the silica sand down wells than ever before. Drying is an integral step in preparing …
The frac sand boom continues to gain traction in the Southern United States, where drillers are pumping more sand than ever down wells in an effort to boost crude oil and natural gas production. Drilling is ramping up North of the border as well, as …
For over a century, rotary equipment has been widely accepted as a preferred means for the pyro-processing of bulk solids, offering distinct advantages over stationary processing equipment. As a cylinder rotates, tumbling, sliding, lifting or showering continuously agitates the material within. These actions ensure that …
This week’s photo is a 3D image of a rotary dryer flight curtain. Flights, or material lifters, are affixed to the interior of a rotary dryer. They work by picking material up, carrying it over, and showering it through an airstream as the drum rotates. …
Advancing flights and knocking systems are two common rotary dryer add-ons. Advancing Flights. Advancing flights work to move material into the dryer, to prevent build-up near the wet feed discharge. Additionally, advancing flights also give material the chance to dry before it moves on to …
This week’s photo highlights several rotary dryers under production at FEECO. The photo was taken in FEECO’s fabrication facility, just shortly after our founding in 1951. For decades, many industries have been faced with the same problem: product moisture. Depending on material composition, moisture can …
