This week’s photo highlights the FEECO Fabrication Facility, where several belt-style bucket elevators are being assembled. In this photo, you’ll notice the center of the boot section contains a spiral, wing-type pulley. Wing-type pulleys prevent material from being pinched between the back side of the …
The best way to control material build-up in a rotary dryer is to prevent it in the first place. Custom Flight Design. Build-up can be prevented through the design of less aggressive flights, or material lifters. Material tends to build-up in sharp corners, and a …
Today’s photo highlights advancing flights in a rotary dryer. Advancing flights help to move, or advance material into a rotary dryer to prevent buildup near the wet feed discharge. Additionally, advancing flights give the material a chance to dry before they hit the next flights; …
Today’s photo highlights a refurbished tire and trunnion wheel. Rotary drum tires and trunnion wheels can become worn over time, resulting in a variety of unwanted characteristics such as pitting, spalling and timing marks. If the wear is left untreated, the weight of the drum …
This week’s photo highlights a trunnion skewing adjustment in action. A dial indicator (bottom left of photo) is used to measure the movement of the trunnion wheel bearings. If the bearings are not positioned correctly, they should be adjusted. The purpose of the trunnion skewing …
This week’s photo comes from the FEECO Fabrication Facility, where our team is assembling castable refractory inside of a kiln. Refractory is a crucial component in direct fired rotary kilns. It insulates and protects the kiln’s shell from high internal temperatures, and also maintains heat retention. …
This week’s photo is a 30” wide x 39’ long troughed belt conveyor under production at FEECO. The conveyor features a channel frame, ideal for use when long spans between supports are not required. FEECO’s troughed belt conveyors are available in configurations 18” to 72” …
This week’s photo shows a thermal image of a rotary dryer. FEECO’s Customer Service Engineers frequently use a thermal imaging camera to assess rotary dryers and kilns during equipment audits or annual inspections. A thermal imaging camera can help engineers to easily see where trouble …
Our photo this week highlights a pin mixer currently under production in FEECO’s Fabrication Facility. Pin mixers are industrial mixers used to condition, mix, micro-pelletize, and agglomerate material. They can be used a pre-cursor to a disc pelletizing or agglomeration drum set-up, or as a …
This week’s photo shows a rotary drum gear before and after replacement. The gear on the left is exhibiting excessive wear and inadequate lubrication. This is an example of extreme wear, and was caused by tramp material entering the gear mesh. At right, the gear …
