Our photo this week is a sand dryer used in processing frac sand. The 8’-6” x 50’ long dryer utilizes co-current airflow to reduce the moisture content of mined sand. The rotary dryer contains an additional 5’ shell length to incorporate flame cut openings to …
Yet another application for biochar looks to be on the horizon; a growing number of studies are proving that biochar could be an effective tool in managing air quality, with one study finding that the charcoal-like material has the potential to significantly reduce air quality-related …
Today’s photo shows the interior of a rotary cooler. The material inside of the cooler is dried distillers grains with solubles, also known as DDGS. DDGS is a is a by-product of ethanol production, and can be used as an animal feed ingredient due to …
While nickel is perhaps most commonly known for its use in coins, it is also an important material in many industrial processes. Nickel’s high melting point, ductility, and resistance to corrosion when alloyed lends itself to a wide range of industrial applications and materials, making …
An important consideration in rotary kiln design is air flow, or the direction in which the process gas moves through the kiln in relation to the material. The cross-flow configuration is specific to indirect-fired rotary kilns. Here, the material and the process gas flow perpendicular …
Drought is becoming a rising concern across the world as water scarcity, changing climate patterns, and the need to feed a growing population continue to dominate the landscape of pressing global issues. As such, the need for soils to be capable of withstanding drought conditions …
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing …
