Mixer Details

Our high performance industrial fertilizer mixers (HPM) are a line of double rotor mixers customized specifically for the fertilizer industry. Use our Double rotors for fast mixing and cycle times (typically one minute), and in these larger sizes, they are better for end to end transportation of minors, adding liquid, and hopper design.
Side brackets support the mixer and the hoppers hang from the mixer. Hoppers over 5000 lb. (2400 kg) required extra support. There is no dynamic load.
Machines will have extra height and ability to add pipes for adding liquid. We can supply liquid systems. All Sealed bearings –do not grease. Rotor seals are a packing gland, spring loaded with stainless spring washers to prevent leaks from starting. Seals always fail while in production, so being able to do a quick fix without having to take the machine apart, is a big advantage. They can groove the shaft which is repairable or prevented with a sleeve. Hardened shaft sleeves are available.
