This week’s photo highlights a ball and tube knocking system. Knocking systems are often implemented to combat build-up inside of a rotary dryer. The systems are usually externally fitted on the inlet end of the dryer, where the incoming material is most wet and sticky. …
Expanded clay aggregates, also called exclay, or lightweight expanded clay aggregates (LECA), are a beneficial material in a growing number of industries – most notably construction and horticulture, with water treatment and filtration applications likely next in line. The unique structure and physical properties of …
As one of the most cost-effective ways to transport material in and around a facility, belt conveyors are employed in every industry working with bulk solids. Their diverse handling capabilities combined with flexible design makes them an essential tool in nearly any setting. But conveyors …
Adding a pre-conditioning step to a process offers many benefits. Pre-conditioning prepares a material for agglomeration, and helps to streamline subsequent processing steps. Advantages include: An optimally prepared feedstock provides consistency to a process. Feedstock that has been pre-conditioned is less likely to …
Biochar, a charcoal-like, carbon-based material with roots in ancient civilizations, has scientists excited over the potential it holds for restoring depleted soils, improving food security, and aiding in climate change efforts when used as a soil amendment. What is Biochar? Biochar is created through the …
Bulk material handling equipment such as bucket elevators and belt conveyors transports material in and around processing and shipping facilities, lending automation and flexibility to industrial operations of all types. While bulk material handling equipment design is relatively straightforward, a number of material- and facility-specific …
Made up of sylvite (KCl) and halite (NaCl), sylvinite is an evaporite mineral that serves as the world’s primary source of potash – a nutrient critical to maintaining global food security. Froth flotation is widely used for separating KCl from NaCl and other undesirable components …
Our photo this week shows a batch rotary kiln test conducted in the FEECO Innovation Center. The batch kiln is used to simulate the conditions of a continuous, commercial rotary kiln. The kiln is lined with a lightweight castable refractory and heated with a propane burner. …
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold beneficiation. Widely used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultra-porous structure, …
As the world continues to move away from fossil fuels, pyrolysis is becoming an increasingly important tool, helping to create a more circular economy by opening up opportunities in the production of alternative fuels from a variety of wastes. The rotary pyrolysis kiln is chosen …
