Rotary drum tires and trunnion wheels can become worn over time, and result in the following changes: Chattering or vibrational noises Pitting Spalling Rolled over edges Timing marks Ridges Taper wear Washboarding The characteristics mentioned above can cause the weight of …
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 …
Efficiently and effectively drying bulk solids is an essential aspect of modern industrial processing, no matter the industry. Among the various technologies available, fluid bed dryers have proven to be both diverse and reliable, as well as capable of processing a wide variety of materials. …
Rotary dryers and rotary kilns share similar thermal processing functions, but each is intended for very different industrial applications. Rotary dryers operate at inlet temperatures between 600 and 1400ºF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other …
The rotary kiln testing carried out in the FEECO Innovation Center is often critical to gathering process data and developing the groundwork for a safe, efficient, and effective thermal processing operation. This testing gives producers the opportunity to predict how their material will behave in …
