Sicoma North America

These actual photographs and videos show the perfect mixing action of the Sicoma planetary mixer from 3 to 60 seconds after material is added. Note that the floor is completely swept by the countercurrent action every 4 revolutions (10 seconds) and that each zone is covered at regular intervals in time.  

← See Planetary mixer in action Other important features and benefits Up to 30% greater pan volume than many others rated for the same output, ensuring that it will carry the full rated load and mix it properly.  Performs equally well on full and small partial batches - the ARMS do the mixing.  Paddles are needed for discharge only.  Large reduction gearbox and oil bath is cool running, good for the life of the mixer.  Compare with others using small commercial gear units in tightly cramped, unventilated spaces that can only withstand intermittent duty without overheating and eventual breakdown.  Sicoma has never had a gearbox failure in over 30 years of production. 5 year / 10,000 hour guarantee on gearboxes. Three-armed stars have better mixing action than two-arm and last longer. Perfect countercurrent mixing action gives higher strength concrete, saves 10 - 15% cement compared with others. Rubber sealed discharge doors run smoothly and eliminate  leakage of water. Optional additional discharge doors, to 4 maximum. Fast and complete cleanout without requiring extra cleanout mechanisms. Hydraulic door  mechanism gives powerful controllable open/close action. Motors and gears rated for occasional startup with full load, without complication of hydraulic coupling. Large half-moon cover (smaller models) or wide segmented covers (to MP3750) giving safe, quick access for cleaning. High-security locking cover latch  disables startup, ensuring safety even if separate lockout switch is overlooked. 15 mm Ni-Hard cast iron liner tiles and mixing blades give 10 times the wear of most other linings*. Small, identical floor tiles are low cost and can be individually replaced. Optional Chromium Carbide cladded plates and paddles available at extra cost for extreme wear applications. Optional rubber blades/paddles for use with aggressive aggregates. Electrical wiring meets UL requirements.  Motors are CE;  UL available. Best value for money in its class. MixTron microwave moisture sensor and controller is fully compatible - perfect for all dry cast mixes.

Safe access Safety is paramount in all Sicoma products.  The MP's half-moon cover allows almost a full 180 degree access on all models;  safer than any other, bar none.  And Sicoma's key-operated safety catch guarantees  that the motor cannot be powered with the cover open, even if the disconnect switch is closed.  Fully gasketted joints and a grilled  inspection hatch complete the package.  The optional hydraulic cover and discharge door can still be operated if power is down by using the hand lever on the hydraulic pump.
Mixing blades Ni-Hard cast iron blades are extremely hard wearing;  they are also easy to adjust and replace.  In addition, they are wear-equalized;  compared with other, symmetrical designs, MP's blades are thicker on the outside edge to exactly compensate the extra wear at these points.  Arms are identical, modular and the upper "fuse" spider arm bends or breaks away if jammed, reducing cost of repair.  Optional rubber, chromium carbide and tungsten carbide blades are available for high wear and special applications. Wear comparison for different materials Hydraulic pump Standard on all models, the hydraulic pump has a  manual actuator to open the discharge door if power is lost. Water inlet is shown beneath pump.
Cement and aggregate inlets Optimal introduction of cementitious ingredients can occur from either side of the mixer, as shown, so as to avoid the rotating planetary gearbox, and in the center of the access cover on some larger models.  Aggregates are introduced at the side opposite to the access cover, through a chute or the optional skip hoist.
Water entry The semicircular water spray bar is standard on models MP1875 and larger (extra cost on smaller models).  It gives optimum distribution of water for all types of concrete; dry cast in particular.  It is important to charge the water within 15 seconds for fastest mixing action, and this system is designed for the job.  If feeding from a tank, a pump may be necessary to reach the right speed.  Note the anti-siphon U-tubes that cut off water feed instantly;  this is important when using a moisture control system. Optional spray nozzles can be fitted to give a washout action on every batch.
Optional skip hoist Sicoma's matching skip hoist is tailored to the mixer to guarantee "no-problem" installation.  It can be made with any height.  Simplifies loading from a low-profile batch plant, occupies less floor space and creates less dust than conveyor. Optional discharge door covers To allow easy inspection and access, the MP mixer is intended for use with a raised sub-floor.  When installed on a mezzanine floor, hinged door covers are available;  these are of expanded steel mesh  construction. Optional air bag dust collector To prevent the inrush of aggregates from forcing out a cloud of dust, the air bag inflates to take up this extra air volume.  It gradually deflates during the mixing cycle to return the dust into the mix.
High pressure washout The standard water outlets are spaced around a 180º spreader bar, angled to give best water distribution (models MP1500 and larger).  High-pressure washout adds spray jets, angled to cover the whole mixer interior, mounted on the underside of the rotating mixing arms.  This awesome washout system is powered by a powerful high-volume pump.  The pump can be shared with a second mixer or manual spray wand.  Power washout system pictorial brochure Pulverizer attachment Some materials tend to form balls or clump.  This powered cutting blade option, powered through the MP's hollow drive shaft, is effective in eliminating the problem.
