Rotary dryers and kilns are an integral part of the many industrial processes that shape our world. From fertilizer and chemical production, to ore beneficiation and even consumer products, these rotary drums provide a reliable, high-capacity setting for accomplishing a number of necessary objectives when …
FEECO’s leaf seals are designed to minimize air leakage into a rotary dryer or rotary kiln. We offer both single and double leaf seals. The single leaf seal consists of a series of overlapping spring steel plates that are mounted to the housing and ride …
Rotary drum seals provide a seal between the rotating drum and stationary housing. This contributes significantly to process efficiency by preventing air from leaking into the drum’s processing environment. What seals are available? FEECO offers a number of seal options depending on the level of …
When working with a rotary dryer or kiln, the sealing mechanism is a critical component in the overall performance of the unit. Sealing mechanisms create a seal between the rotating drum and the stationary housing, preventing air or process gas from leaking into the system. …
This week’s photo shows a warped leaf seal. Extreme heat during a kiln’s operation caused the seal to curl away from the drum, and cool into this deformed shape. It was later replaced by a FEECO Customer Service Engineer. Leaf seals minimize air leakage into …
Holding the appropriate temperature within a rotary kiln is what allows the desired chemical reaction to occur. Sustaining that temperature, however, can be difficult if the right seal is not chosen. Almost all rotary kilns run at a negative pressure, meaning gas doesn’t leak out, …
