S. Howes



Our Powermix mixer is designed for strenuous industrial usage across a wide variety of industries. Extra heavy gauge steel is used for the tank and end plates, and powerful, heavy-duty drives are used to ensure years of reliable operations.

Over 16 standard models are available from 6 to 419 cu. ft. (3/4 full). Custom models available up to 1,500 cu. ft.

Mixing is accomplished using either S. Howes’ original double ribbon or an adjustable paddle agitator. Custom assemblies are also available.

Details of Standard Powermix Construction

  • Materials of construction are up to 50% heavier than that of the Mixall model, for abrasive and more dense applications.
  • End plates are reinforced to provide stiffness and support. Blind end plate is bolted to the tank and the drive end is welded – both at 90 degree angles – no radius. Structural channel is used for reinforcement of the tank walls.
  • Uniquely designed double ribbon type agitator assembly features ribbons welded to cross-arms. Paddle agitators feature paddles that can be either welded or bolted to cross-arms.
  • Tubular shafts with welded journals are a standard for all Powermix models. Shafting materials are made heavier to carry up to twice the horsepower of Mixall models.
  • Drive-end bearings and journals will withstand high starting torque at maximum recommended horsepower. Bearings are 2 1/2 times the calculated radial load. High quality, self-aligning type bearings are furnished on all Powermixes. Bearings are mounted to allow for alignment of the cylinder and have lock screws to secure the bearing locations.
  • Support cradles under the tank are available to provide improved distribution of heavier loads.
