Rotary dryer sizing and design is based around a material’s unique processing needs, or at least they should be. A custom rotary dryer will produce the most ideal results. The following material characteristics should be considered in sizing and designing a dryer: For more in-depth …
Catalysts continue to play a growing role in modern industry, carrying out an array of processes that otherwise might not be possible, promoting more sustainable industries through efficient processing, reducing toxic emissions, and more. As the use of catalysts grows, so too does the amount …
Rotary kilns, like any other high-performing piece of equipment, need regular inspection and maintenance to ensure ideal operation. The list below highlights the areas of a kiln that should consistently be inspected: Prevention is key when it comes to maintaining a rotary kiln. Regularly …
The trunnion wheel, also known as a trunnion roller, is a key structural component of any rotary drum base. What trunnion wheels are available? FEECO supplies trunnion wheels in 4140 or 4340 stainless steel. Sizes are available all the way up to 48” in diameter. …
Rotary dryers are known as the workhorses of the industrial drying industry, but like any robust equipment, they are not immune to processing challenges. The challenges often vary on the specific material being processed, with some requiring additional preparation, and others, routine maintenance. Generally speaking, …
This week’s photo highlights several rotary dryers under production at FEECO. The photo was taken in FEECO’s fabrication facility, just shortly after our founding in 1951. For decades, many industries have been faced with the same problem: product moisture. Depending on material composition, moisture can …
Generally speaking, rotary dryers are the sand dryer of choice when it comes to frac sand, offering many benefits over other drying options. One reason rotary dryers are chosen over other dryer types is for their ability to accept large throughputs. Rotary dryers are high …
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 …
This week’s photo shows two types of flights in a rotary dryer: standard lifting flights, and advancing flights. Flights, or lifters, are positioned inside the rotary drum and play a fundamental role in the drying process. As the drum rotates, flights lift the material, and …
Rotary kilns (also known as rotary calciners) are used to heat solids to a predetermined temperature in a controlled processing environment in order to create a chemical and/or physical reaction. While rotary kilns have long been used in producing cement, their flexible capabilities have extended …
