Troubleshooting Rotary Drum Vacuum Filters

Cloth snags and tears on metal scraper blades. The scraper blade is a wear part. When a metal scraper blade wears, it sharpens, which can cut through industrial filter media. The Micronics Engineered Filtration Group offers a dual-density scraper blade, which has a tip that wears away slowly as it rubs against filter cloth.

Bailer vent pulls vacuum. You can test if the bailer vent is pulling vacuum by dropping a scrap of tissue paper near its outlet. If the scrap is pulled in, then the drum is leaking vacuum within the internal piping of the shell itself.

Bailer vent leaking slurry. Slurry coming out the bailer vent indicates that the drum has a leak. The Micronics Engineered Filtration Group is geared up to come onsite and make repairs to your drum. We can also sell you a replacement shell to fit in your current configuration, and refurbish the original, providing a spare for next time.

Whistling noise when the drum is running. Either the valve spring needs adjusting, or your wear plate needs replacement.

Production loss – thinner, wetter cake. A worn-out valve can cause timing issues, loss of vacuum, and even halt production. We provide standard replacement valves as well as abrasion-resistant valves.

Drum filter shakes and clangs. This can indicate worn-out bearings. Do yourself a favor and replace them with the Micronics Engineered Filtration Group’s self-lubricating bearings.

Excessive downtime while installing drum cover. If your crew is using a mallet and dog bone-shaped tool to install filter cloth, this hand caulking hammer kit can save you time and man-hours. Save your workout for the gym!

These are some of the common issues that can arise. It is better to troubleshoot your Rotary Drum Vacuum Filter and replace worn parts when the symptom first appears, rather than waiting for a complete breakdown. If there isn’t a simple fix, our trusted Territory managers can come to check out the filter with one of our Equipment Specialists.

Wear Parts for Rotary Vacuum Drum Filters

Industrial filter media, or filter cloth, refers to the drum cover or belt. Depending on your process, operating temperature, and pH of the slurry, certain fabrics outperform others. We have created a textile questionnaire that, once completed, allows our industry specialists and textile engineers to recommend the filter media that is best for your process.
