Mixers & Blenders Reworked Mixer Gear Design for Quieter Running
Neptune has reworked its mixer design after user pointed out an opportunity for Neptune to reduce the perceived sound levels being emitted from the gear-train on several of its mixer lines.
This was especially eminent the early stage of the mixer’s life–cycle, when the unit was still in the “break-in” period. With that feedback in mind, Neptune worked closely with its gear supplier to optimize the gear-tooth profile by increasing the American Gear Manufacturers Association (AGMA) Quality Class from a level 6 to a level 9, resulting in tighter manufacturing tolerances on the mesh and backlash, and an improved running-surface finish.
These changes, Neptune states, have resulted in lower perceived and measured sound levels. The mixers are suited for waste and water treatment as well as batch-chemical operations with materials such as paints, polymers and pharmaceuticals with viscosities from one to more than 25,000 cPs.
