Plant Mixers

Concrete Products surveys the broad range of equipment offerings for manufactured or packaged dry mix concrete and ready mixed production. Engineers and manufacturers continue to focus on improved safety and maintenance aspects, along with energy efficiency in planetary, pan, twin shaft and ribbon blade models.


ACT marks its 30-year anniversary with an upgraded high shear, countercurrent planetary mixer. The Wiggert HPGM V9 features improved performance, durability and operation over prior series. The model has three options for batch water addition: weighed, volumetric, and injection from side walls, the latter resulting in reduced wetting of surfaces for shorter clean-up time. New protective coverings shield components from impact, debris and water. Enlarged mixer access doors have electromagnetic safety locks. Among additional enhancements are mixer tool durability, standard soft start control for lower AMP draw, and flush mounted bolt heads to reduce concrete buildup. — Advanced Concrete Technologies, Greenland, N.H., 603/431-5661;





The manufacturer cites systematic design and performance upgrading of its twin-shaft mixer ever since introducing the concept with a charter model in 1888. Aiming to set the benchmark in concrete mixing technology, BHS has thousands of twin-shaft units in operation throughout the world. An optimized tool design and arrangement allows for consistent three-dimensional mixing that ensures full load homogeneity with very short cycle times. BHS twin-shaft batch mixers are available in sizes from 0.7 to 12 yd. and can be fitted with a wide range of options. — BHS-Sonthofen Inc., Charlotte, N.C., 704/845-1190;



Eurostar models suit installations where consistent concrete batching is required at a high rate of accuracy and performance. Unique among planetary mixers on the market, they have a counter current mixing action yielding homogeneous loads at fast cycle times. The counter current design suits dry or conventional slump wet cast, self-consolidating and ultra-high strength mix output. The robust Eurostar mixers are built to precision tolerances with flatness and roundness characteristics to minimize wear and ease maintenance schedules. Company’s in-house engineering team can provide solutions for custom designed plants for all production sizes, retrofits, and automation levels. — Cleco Manufacturing, Hudson, N.H., 603/886-5472;



Techmatik planetary mixers deliver fast, high shear, counter-current mixing action. The durable machine design features a heavy-duty, planetary gear box which is made and assembled at Techmatik’s factory. Available in eight sizes for .25- to 2.5-meter output, the SPM Series mixer suits heavy-duty applications where high strength, self-cleaning discharge (color applications) and fast cycle times are required. Standard mixer features include Hardox 500 and 700 steel linings; hydraulically controlled discharge flap; emergency opening by manual pump in the event of power failure; mixing unit with polyurethane blades and scrapers; plus, air bag venting systems.

The company’s 86,000-sq.-ft. headquarters houses advanced equipment planning, tooling and manufacturing, plus staff capable of designing and constructing concrete batch plants from the ground up. — Mixer Systems Inc., Pewaukee, Wis., 262/691-3100;






Company offers horizontal dual axis and planetary mixer series. The ORU MD is equipped with two horizontal mixing axes rotating in sync in opposite directions; models are equipped to produce conventional and high performance mixes specified in all construction conditions. ORU MS planetary vertical mixers with coaxial motor can likewise mix any type of concrete: dry cast and conventional or high slump. The MS and MD series are part of a complete equipment offering from a global source of concrete plant solutions. — IMER Group USA, Capitol Heights, Md., 301/336-3700;


New AtlantisSKAKO

The Rotoconix and Atlantis series lead company’s plant mixer offerings. With patent-pending components, the Rotoconix cone model suits ultra-high performance mix production. It features reversible turbo whirler, screw and rotating cone, and is available in 375-, 750-, 1,500- or 2,250-liter sizes for output of .3- to 2-yd.

The countercurrent Atlantis mixer is available in nine sizes, from 125- to 6,000-liter, for .10- to 5-yd. output. Features contributing to safe, easy operation and maintenance, plus robust, fast cycles include anti-dust airbag; inspection hatch; inlet/skip hoist; water proportioning device; semi-automatic, electro-hydraulic sampler; automatic, high-pressure cleaning system; and, two-level shovel technology.

Roto 1


Robust cycle capability equips the Ocmix RG twin-shaft mixer to save on cement for a given quality of concrete, compared with tilt, drum and pan mixers. Standard features include extensive paddle coverage, extra-hard wearing liner plates, positive shaft seals that can last for the life of the mixer, plus easy-access, single-day shaft and bearing replacement. Mixer sizes range from 2 to 10.5 yd., yielding 80 to 427 yd. of compacted concrete per hour.

Ocmer planetary mixers feature a one-piece gearbox with hydraulic coupling in the larger sizes. The mixer body is wider than comparable models and its high-back, scooped paddles ensure thorough mixing. Paddles are certified 600 Brinell ni-hard cast iron; floor is 18-mm Hardox steel. Mixer sizes range from 0.5 to 6 yd., yielding 10 to 120 yd. of compacted concrete per hour.

Both mixers include optional piggyback feed systems, allowing the critical parts of the plant to be selected and delivered as pre-assembled units. This reduces down time for upgrade and ensures successful installation plus trouble free, optimized performance.
