The Ocmix SF planetary concrete mixer produces high quality concrete at high speed with outstanding reliability;  its body is wider than most, ensuring that its multi-star planetary mixing action gives the fastest and most complete mixing of full size batches with no dead zones.  Its motor is more powerful than most too, making easy work of high-density mixes.  Large, fully sealing discharge doors and scooped paddles discharge even SCC concrete with ease.   Low sidewalls and wide opening access covers make cleaning and maintenance easy and safe.

In the planetary (or countercurrent) design, one to three mixing stars (depending on size) rotate individually while also rotating around a central point, allowing each arm to cover the whole mixer floor in a number of revolutions.  This powerful mixing action is both fast and thorough, resulting in a mixing time, after water is added, of 30 seconds or less for most types of concrete.  The result is more concrete per hour for the same size plant, as well as better consistency and greater strength or, on the other hand, a saving on cement that can pay for the mixer in a short time.  The planetary design is the best choice for dry precast concrete, colored mixes and for smaller batches of SCC and wet-cast due to its intense, compulsory mixing action and complete cleanout.

The 3-bladed mixing stars and scraper assemblies are fabricated rather than cast, for extra strength.  They are stronger than most and flex or even bend if they encounter an obstruction, rather than breaking, reducing the risk of a "train wreck".

Paddles are of certified HB600 ni-hard cast iron for long life.  Their scooped design allows all types of mix to be mixed thoroughly and discharged with ease.  Other paddle designs are available for special applications.

Water and admixture inlets are standard, making installation and startup fast and trouble free.

PIGGYBACK CEMENT AND WATER SCALES

Cement and water scales can be integrated into the mixer cover, making installation fast, easy and risk-free as well as ensuring the fastest mixing cycles.  Cement scale is at left and water scale at right, behind the optional weighed admix containers.  Optional skip hoist can be seen behind the piggyback assembly.
All Ocmer plant accessories are heavy gauge hot galvanized steel and scales are fitted with commercially available butterfly valves for reliable discharge. 

MIXER WEAR LINER

The standard liner is 18 mm wear resistant Hardox 500 steel;  tough but not brittle, for floor plates and Hardox 400 for walls.  Other lining materials, including Hardox 600 and Chromium Carbide cladded steel, are available on special order.

The High Pressure Washout option includes two rotating jet assemblies that force powerful jets of water in every direction, cleaning every surface thoroughly.  A high-power manual gun is supplied for hand cleanup of the remaining difficult spots

Mixing cycle and mixer charging sequence:  we recommend charging the dry ingredients and pre-mixing before water is added.  This has been proven to improve coating of aggregates and give faster overall mixing cycle times.  More.
