Gentle mixing and time-tested features make the slump mixer an industry favorite for low slump concrete. Specially designed spiral blades and figure 8 mixing action assure consistent and complete mixing every batch.

This low shear mixer offers low material degradation. The slump mixer is perfect for precast, prestress or construction site production and is adaptable to all types of central mix operations.

Single Shaft Ribbon mixers are available in a wide range of sizes from 2 - 10 cubic yards (1.5 - 7.6 cu m) compacted output capacity. The low profile of the mixer requires less overhead room than conventional mixers. The mixer design allows for precise control of the discharge rate.

Optional Enhancments

Mixer Washdown

A high-pressure washdown system reduces operating costs and time. Any mixer can be equipped with this cleaning device. An operator uses a high-pressure wand to clean the mixer. The mixer washdown equipment is comprised of a high volume, medium pressure triplex plunger pump unit. This equipment also includes a 40 horsepower motor, 50 gallon (189 l) surge tank, heavy-duty pressure valving, self contained shutdown level system and electric control panel.
