Our photo this week is a damaged thrust roller. Damage occurred because the thrust roller either stopped rotating, and the rotary drum ran hard against its left side. The thrust could also have become damaged as a result of a bearing failure; the bearing may …
Proppants are hard microspheres that are injected into well bores to “prop” open rock fissures, allowing oil and natural gas to flow out. While frac sand is the most commonly used proppant, ceramic proppants offer a tailored solution in demanding drilling settings. Greater crush strength. …
This week’s photo shows a damaged rotary drum tire. Tires can become damaged if: Tire replacement is often the best solution to tire damage. Welding can also be an option, though it is a last case resort, and a temporary solution. Regular inspections and maintenance …

This week’s photo highlights a pan pelletizer’s binder spray system. The spray system, or nozzles, are used to disperse binder. Non-pressure agglomeration technologies, such as pelletizing on a pan pelletizer (also known as a pan granulator or disc pelletizer), often requires the assistance of a …
As one of the key nutrients required for plant growth, nitrogen is essential to life on Earth. It plays a critical role in crop production and ultimately, producing food for the Earth’s inhabitants, particularly as the world looks to feed an exponentially growing population. One …
This week’s post highlights a series of images: rotary tire wear patterns. A rotary drum tire is a support structure for the drum, and provides a place for pressure to be absorbed. As with any piece of equipment, they must be inspected and serviced, if …
