Wipes Grinding

Flushable and sanitary wipes have become a major issue for wastewater treatment plants worldwide. Unlike toilet paper, wet wipes fail to disintegrate. They clog pumps, cause backups, and accumulate grease. Franklin Miller grinders are specifically designed to handle flushable wipes with ease and eliminate the issues associated with them.

TASKMASTER® grinders with CUTTER CARTRIDGE® technology have the unsurpassed ability to reduce difficult wipes to fine bits to alleviate clogs. These cutters have sharp, shark-like teeth that effectively rip through single or multiple clumped wipes and reduce them into small bits.

With rugged construction, precise alignment and optimized profile design, these cutters deliver superior performance on wipes and other stringy materials from day one and over the long run.

Sludge Processing

With our innovative hollow spherical rotor SUPER SHREDDER® and our TASKMASTER® twin-shaft grinders, we have the ability to combat plugging problems associated with sanitary wipes. Franklin Miller will have the right processor for your needs. Our grinders improve the reliability, life and performance of your pumps, centrifuges, digestors and other process equipment.

The SUPER SHREDDER utilizes a low speed and high torque action to chop, grind and shred solids into fine bits that can be easily processed by downstream equipment. Its innovative open-center spherical rotor design maintains a high percentage of open area—making this unit practically invisible to the flow. In fact, it can handle higher flows than any other inline grinder available.
