Rotary coolers are essential tools in industrial processing facilities across the globe, cooling product for subsequent handling, storage, or bagging. How does a rotary cooler work? A rotary cooler works by passing ambient or chilled air through a horizontal rotating drum. Material is fed into …
Our photo this week is a sample of coal fines. Coal is a reliable energy source used around the world, but its dusty form is less than desirable to process and transport. Low rank coals are especially problematic, as they generate large amounts of dust, …
A flexible and popular means of drying bulk solids, fluid bed dryers are often a top contender in the selection of an industrial drying system. And as with any industrial dryer, fluid bed dryers have inherent advantages and disadvantages that make them a better fit …
Rotary drum tires and trunnion wheels can become worn over time, and result in the following changes: The characteristics mentioned above can cause the weight of the drum to be unevenly distributed, which in turn, can affect other drum components. Premature equipment failure can then …
Pin mixers offer an effective approach to mixing, de-dusting, and agglomerating solid and liquid feed components. What follows are some of the most frequently asked questions (FAQs) surrounding these diverse continuous mixers. How does a pin mixer work? A pin mixer consists of a horizontal …
This week’s photo highlights a pneumatic hammer knocker. Hammer knockers are one of many knocking system options FEECO provides to help combat material build-up inside of a rotary drum. Pneumatic hammers are mounted above a strike plate on the drum. An operator controls the hammer …
Fluid bed dryers offer an efficient and effective means of drying bulk solids for a variety of industries. For facilities considering the use of this industrial dryer, understanding the basic principles behind fluid beds is essential. The following provides a comprehensive overview on the key …
Dams are used to increase the retention time or bed depth in a rotary kiln. Material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam and discharges from the rotary kiln. Since most rotary kilns …
The ability to control the sizing of bulk solids has become a critical aspect to the success of many processes and products, allowing for more efficient processing, more predictable results, and ultimately a better end product. Agglomeration offers the unique opportunity to fine-tune particle size …
This week’s photo shows laser alignment in progress. A FEECO Customer Service Engineer is performing the laser alignment on a rotary drum. A state-of-the-art laser tracking system uses a laser beam to measure 3D coordinates (angles and distances) along the rotary drum, which is then recorded and analyzed …
