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 →
Rotary kilns use extremely high temperatures combined with controlled retention times to cause a chemical reaction or phase change in a material. At certain temperatures (different per each material), a material will undergo a chemical reaction or phase change. This is often necessary to bring Continue reading →
In the complex production required to transform spodumene concentrate into lithium compounds such as lithium carbonate or lithium hydroxide, calcination plays a key role in not one, but two parts of the process, making it an essential technique in efforts to exploit this increasingly important Continue reading →
Rotary kilns use heat to cause a physical change or chemical reaction in a particular material, and can be utilized to carry out a variety of processes. One of the more common processes carried out in a rotary kiln is heat setting. This refers to the act of Continue reading →
The lithium-ion battery market has seen explosive growth in recent years, largely in response to the growing electric vehicle market, coupled with the increasing use of consumer electronics and a desire to advance energy storage technology for renewable energy applications. A Grand View Research report Continue reading →
This week’s highlighted resource is a Slideshare presentation on rotary kiln customization. Rotary kilns are incredibly flexible and can be customized to meet a variety of different thermal processing needs. This Slideshare presentation looks at some of the many options used to customize rotary kilns Continue reading →
Our photo this week shows an NPK fertilizer granulation plant. The photo was taken around the early 1960s and showcases a rotary dryer (the larger drum on the bottom), and a granulation drum (the smaller one above the dryer). Now a typical NPK granulation process, Continue reading →
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 Continue reading →
This week’s highlighted resource is a project profile on three frac sand dryers used in an in-basin sand plant. The in-basin frac sand trend has been sweeping the industry. This project profile highlights an in-basin project FEECO worked with to provide three custom rotary dryers Continue reading →
From foods to minerals, a variety of industries use industrial coolers to cool bulk solids for subsequent handling, storage, or transportation. When selecting industrial cooling equipment, the choice often comes down to a rotary cooler or a fluid bed cooler. In general, rotary coolers Continue reading →
