Rotary kilns have become an essential bulk solids processing tool throughout a number of industries; their ability to facilitate physical and chemical changes through carefully controlled thermal treatment is nearly limitless in application. Because rotary kilns utilize high temperatures to initiate and carry out reactions, …
Diatomaceous earth, also known as diatomite or kieselguhr, is an industrial mineral essential to everything from producing beer and wine, to extending and whitening plastics. The diverse application of diatomaceous earth demands great variation in the material as a feedstock, and producing the different qualities …
Knocking systems are physical enhancements placed on the exterior of a rotary dryer to counteract sticking inside of the drum. They are most commonly fitted on the inlet end of the dryer where material entering in is the most wet and tacky. Build-up can occasionally …
As the gypsum industry knows, changes in a material’s moisture content will influence manufacturing in many different ways. For example, a reduction in moisture can greatly impact material handling or prepare gypsum for subsequent steps in the manufacturing process. Gypsum dryers, also known as rotary …
Sugar beet pulp, a by-product of extracting sugar from sugar beets, has been receiving growing attention in agriculture as of late for its value as an alternative to corn silage and because of the many benefits it can offer to livestock producers. And as the …
The rotary dryer is the industrial dryer of choice for everything from minerals and ores to fertilizers and specialty chemicals. One decision buyers are often faced with in selecting a rotary dryer for a given application, particularly when looking to dry high-moisture materials such as …
Catalyst regeneration via thermal desorption has emerged as a solution for industries grappling with spent catalysts, which pose liability risks and waste management challenges. As processors seek to lower operating costs and minimize their environmental footprint, many are turning to catalyst regeneration through this thermal …
Today’s photo shows the gear mesh of a gear and pinion drive, the mechanism that causes a rotary drum to rotate. The face of the teeth here are worn, an indication that the gear should be replaced, or they may break off. In most cases, replacement …
The drive assembly is the component that causes a rotary kiln to rotate. While a variety of drive assembly arrangements are available, the selection of one type over the other is dependent on the drive horsepower and the size of the kiln. FEECO offers the …
Bulk solids processing is perhaps the most fundamental aspect of modern industry. Each and every day, bulk solids are handled and processed by the ton to convert mined ores into refined metals, produce market-ready products from raw materials, and so much more – all to …
