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 …
The electric vehicle and battery markets are calling for unprecedented amounts of lithium; in 2016, demand for the lightweight metal rose by 26%, and is predicted to climb an additional 39% in 2018. By 2025, experts anticipate demand is likely to increase by a staggering …
The looming threat of environmental contamination, climate change, and a growing need for raw materials has given way to a new age in how the world views and manages waste. As the population puts a strain on existing resources, never before has it been more …
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. …
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, …
