Breeching assemblies provide a place for controlled material feed and product discharge in rotary dryers, coolers, kilns, and granulators.
Paired with the proper seal, breechings also prevent ambient air ingress into the system.
Breechings can become worn over time as a result of abrasive or corrosive materials, exposure to the elements, physical damage, or the presence of tramp material but must be kept in adequate working order to maintain overall process efficiency and product quality.
AVAILABLE BREECHINGS
FEECO offers custom inlet and discharge breechings for a reliable and efficient solution tailored to your unique process and facility needs. Breechings are available in a variety of different materials of construction, with the two most common being stainless steel and carbon steel.
INDICATIONS THAT A BREECHING MAY REQUIRE REPLACEMENT
Breechings exhibiting any form of wear should be immediately addressed. While repair may be an option in some cases, moderate to severe wear will require replacement. Signs of wear may include:
- Holes
- Thinning walls
- Structural damage
Frequently Asked Questions (FAQs)
Breechings only require replacement if they become worn; some breechings may last the life of the drum. Some wear is repairable, while more aggressive wear such as holes, thin spots, or other damage, will typically require replacement.
The lead time for breechings is typically between 8 and 14 weeks, though this may vary.
Yes. The seal should also be evaluated when replacing a breeching. If seal damage is present, the seal and breeching are best repaired or replaced at the same time to avoid additional downtime.
The cause of breeching failure should also be identified prior to ordering a new one, as this could be addressed through an upgraded design. For example, if corrosion was the issue, upgrading to stainless steel construction could reduce the potential for future corrosion problems.
