The
Ocmix SF concrete mixer is a leader in planetary mixer technology; its
wide pan and multi-star mixing action gives
fast and complete mixing with no dead zones. Large, fully sealing
discharge doors and scooped paddles discharge even SCC with ease. Low sidewalls and wide opening
access covers make access easy and safe.
The planetary (or countercurrent) design has one to three mixing stars (depending on size) that rotate themselves 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 greater throughput, giving you 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. The planetary design is the best for dry precast concrete and for wet-cast and SCC is preferable to the twin shaft design for smaller batch sizes. The reason for this is its intense, compulsory mixing action and complete cleanout.
Ocmix mixers are made in Italy. Ocmer's policy is "PQRS" - Performance, Quality, Reliability and Service.

GEARBOX Ocmix SF's large horizontally arranged gearbox combines speed reduction and planetary action in one rugged, reliable unit, making service far easier than with double gearbox models. The motor couples to the gearbox through a hydraulic clutch, removing danger to the gears when shock loads are encountered and allowing repeated starting with a full load. If the gearbox ever has to be removed, its wide circular mounting flange allows it to be lifted straight out. Ocmix gearboxes are guaranteed for 5 years / 10,000 hours. The mixing stars and scraper assemblies are fabricated rather than cast, allowing them to give or even bend if they encounter an obstruction, rather than breaking, reducing the risk of a "train wreck". |
SECTIONAL BODY, DISCHARGE DOORSOcmix SF's body breaks down for shipping and also makes for easy erection. The body separates at the discharge doors. Up to four doors can be fitted; each door is rubber sealed for full watertight operation and is hydraulically operated for precise, non-jamming operation. Paddles are of true HB600 ni-hard cast iron for long life. Their scooped design allows all types of mix to be discharged with ease. Other paddle designs are available for special applications. Ocmix SF's powerful countercurrent mixing action saves 10 to 20% on cement compared with pan and drum mixers. The payback time can be as short as one year. And the pan, being wider than most, mixes more thoroughly. |

SKIP HOIST OPTION
The optional skip hoist bolts onto the mixer during installation, making erection quick and easy. Ocmer skips use a double balanced rope system for safety. An optional air bag collects dusty air displaced during discharge of aggregates into the mixer, allowing a small dust collector to maintain a dust-free environment inside the plant. Water and admixture inlets are standard, making installation and startup fast and trouble free.

PIGGYBACK CEMENT AND WATER SCALESCement and water scales can be integrated into the mixer cover, making installation easier and ensuring the fastest mixing cycles. Cement scale is at left and water scale at right, behind the optional weighed admix containers. 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 discharge. MIXER WEAR LINERThe standard liner is 18 mm wear resistant Hardox 500 steel for floor plates and Hardox 400 for walls. Other lining materials, including Hardox 600 and Chromium Carbide cladded steel, are available on special order. More |

HYDRAULIC, GREASE AND WASHOUT SYSTEMSDischarge doors are hydraulically operated. If power is lost, the manual actuator can be used to open the door. For maintenance-free operation, Ocmix SF has automatic lubrication of the main bearings, giving you peace of mind. Optional High Pressure Washout system uses rotating jets to carve away the day's buildup, leaving a clean mixer that requires only minor touchup with the powerful manual gun.

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.
