This week’s photo shows the leveling of trunnion bases. Leveling a rotary drum’s trunnion bases is part of a new drum installation, and is done prior to laser aligning the bases. The goal is to get the bases to within 1/16” with respect to spread, …
The once beleaguered US mining industry is seeing a flurry of indications that the sector is headed for an upward swing; efforts to move toward a low carbon economy, combined with pro-mining legislation are causing excitement within the industry, promising long awaited growth in many …
Agglomeration is commonly used to upgrade material fines into a granular product. It can also be used to transform sludge-like materials into a dry, granular form. There are many reasons to agglomeration a material. The choice to agglomerate often stems from a material problem, be …
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. …

Our photo this week is a frac sand bucket elevator. FEECO designed and constructed several centrifugal-style bucket elevators for a frac sand processing plant located in Wisconsin. The various bucket elevator capacities were 10 TPH, 250 TPH, and 500 TPH, with the discharge heights of …
As the global population expands and water quality issues continue to make headlines, never has it been more important to conserve water resources to our fullest ability, and to ensure that the water available to us is clean and contaminant-free. Simultaneously, researchers and scientists everywhere …
Our photo this week is a 3D indirect rotary cooler. An indirect cooler consists of a rotary drum, stationary housing, water trough, and water collection system. These components work together to cool hot material within a controlled environment. The stationary housing encloses the rotary drum, …
This week’s photo highlights a rotary drum temperature inspection. An IR gun, pictured, is directed at the rotary drum, to record the surface temperature of the object in sight. Items such as the drum shell, drive components, bearings, and even the material as it discharges …
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 …
