PLANETARY MIXER - features

Gearbox

Ocmix CV's large horizontally arranged gearbox in the pan-style mixer 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 on 1 cu.m. and larger models, 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 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".  Arms are heavier than any other and optional polyurethane sleeves give even more protection.

Sectional body, discharge doors

Ocmix CV'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 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. 

The Ocmix CVmixer'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.  Its standard design ensures that everything will work as expected with no startup issues.  Ocmer skips use a double balanced rope system and safety cutoff switches to make this skip hoist compliant with all regulations and ensure your personnel are safe at all times.

An optional air bag collects dusty air displaced during discharge of aggregates into the mixer, allowing only a small dust collector to maintain a dust-free environment inside the plant, saving extra cost.

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

Integrated cement and water scales

Cement, water and other 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.  Use of pre-designed and assembled scales gives you the assurance that everything will fit when installed and will work exactly as expected from a standard and tested design.  The optional skip hoist can be seen behind the mixer feed scale assembly.

All Ocmer plant accessories are heavy gauge hot galvanized steel and scales are fitted with commercially available butterfly valves for reliable discharge.  Solid performance, year after year.

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.  Optional urethane covers on mixing arms greatly prolong their life.

 

Hydraulic and greasing systems

Discharge doors are hydraulically operated, giving powerful non-jamming action and precise positioning.  If power is lost, the manual actuator can be used to open the door. Rubber seals prevent leakage of water and fines during operation.

For maintenance-free operation, the Ocmix CVplanetary mixer has automatic lubrication of the main bearings, giving you peace of mind.

Parts

Parts are stocked at our Montreal plant with same day shipment throughout North America.

High pressure washout

 

The High Pressure Washout option includes two or three 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.  This sytem saves personnel from the danger of climbing into the mixer as well as reducing cleanup time, giving the crew an extra half-hour of production every day.

 

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.
