Rotary kilns are a high-temperature thermal processing device that serve as a vessel to cause a chemical reaction or physical change in a material. As a result, there are many types of processes that rotary kilns, also called calciners, can be used for. The type Continue reading →
Kaolin clay, also known as China clay, is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing. Most notably, kaolin is lauded Continue reading →
Electronic waste, or e-waste, is continuing to capture global attention thanks to a litany of issues associated with the waste, ranging from environmental hazards to humanitarian concerns. As growing amounts of the waste add to fears of a looming crisis, efforts to recover valuable materials Continue reading →
Rotary drums can be configured to serve as a variety of different pieces of equipment, including a rotary dryer, cooler, kiln, granulator, or even a coating drum. With such diverse employment, these robust systems can be used to accomplish a variety of goals across a Continue reading →
Rotary dryers are used prolifically throughout bulk solids processing applications – from fertilizers and soil amendments, to minerals, specialty chemicals and more. In fact, new applications in which rotary dryers are being implemented are constantly on the rise. Whatever the application, rotary dryers are often Continue reading →
Rotary dryer misalignment is oftentimes the result of improper base installation. Misalignment in the base will quickly spread through the rest of the drum, causing wear and damage to other drum components. In addition, misalignment can occur naturally over time as part of normal rotary Continue reading →
Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their jobs. Heat transfer is how heat moves from one source to Continue reading →
