What is the difference between Filling Capacity, Uncompacted Output and Compacted Output?

When the mixer is filled to its DRY FILLING CAPACITY, as the stone, sand and cement mix, the air spaces between stone chunks get filled with sand, and the air spaces around the sand grains get filled with cement. The density goes from about 100 lb/cu. ft. to 150 as it is mixed. Even the spaces around the cement powder get filled with water. The whole volume reduces by 20% or more as a zero slump mix is made. But this zero slump mix still has lots of air spaces in it. If discharged in this state, you get an UNCOMPACTED YIELD of 20% less than the mixer capacity. When the mix is vibrated in the mould or form, all this extra air is expelled and it compacts by a further 15 to 20% to give the COMPACTED YIELD, which is 2/3 of the dry filling capacity. What does this mean to the user? It depends on the application: If the user needs 3 slump or less, the container (Tuckerbilt or bucket) capacity must hold the UNCOMPACTED YIELD. If the user needs 6 slump or more, the container (Tuckerbilt or buck

Why do Sicoma mixers not use cleaning rings on their shafts?

Heavy steel cleaning rings are used by many other manufacturers, but Sicoma refuses to add them because of the damage they do to the concrete. Aggregate gradation is affected detrimentally, reducing strength in unpredictable ways. A properly designed paddle, arm and hub is self-cleaned by the intense mixing action there are no dead spots and at the end of the day, little or no buildup should be evident on these parts. Better solutions through better engineering and innovation. Everything is subject to modification without prior notice. For specific requests, we will refer to our technical department.

Why do we say the gearbox runs cooler?

Its a fact that the MAO gearbox runs cooler than several others, and as a result does not require an oil cooling unit. This reduces its complexity and increases reliability while reducing its price. We say that this is due to its 2-stage design, but this is a simplification. In fact, it is due to the higher efficiency of this particular gearbox, which in turn is mainly due to the 2-stage design. The speed of the motor, 1750 rpm, must be reduced to allow the mixer shaft to turn at 24 to 27 rpm. This is done with a 2:1 belt reducer followed by a 36:1 gear reducer. Every pair of gears creates a little friction which results in power loss. If everything else is equal, each set of gears will add to the total power loss, so the higher the number of stages, the higher the power loss. Take model AV4500, which uses two 55 HP motors. Each motor consumes 41 KW (41,000 watts) when running at full load. If each stage of the gear reducer looses just 0.5% of the power in friction, a 2-stage reducer wi

Why does Sicoma use Ni-Hard cast-iron liner plates?

Previously the standard liner for Sicoma and many others was 10 mm Hardox steel plate. This is becoming hard to get and expensive. Although Ni-Hard is even more expensive, Sicoma has standardized on this material. Its 500 HB hardness and 15mm thickness give it more wear life than Hardox of the same thickness and lower hardness and it costs you nothing extra.

Why does the Sicoma planetary mixer have a shorter scraper blade tail than some?

The good mixing action of Sicomas blades allows faster and more complete cleanout; it simply does not need a wide scraper tail to clean out efficiently. A larger tail causes dead spots in the mixer which increases the mixing time, or reduces homogeneity of the mix. Another manufacturers attempt to give fast cleanout is to use a descending scraper blade. This is both unnecessary in Sicoma mixers and elaborate, giving higher maintenance costs in those that use them. Sicomas planetary is well designed and simple in concept, reducing future headaches and costs. Everything is subject to modification without prior notice.

How does a full mixer still mix almost as effectively and fast as a partial batch?

Because in Sicoma mixers, the ARMS do the mixing. They cover from top to bottom and every cubic inch of the mixer volume many times each minute. The angled blades create pressure in front and a void behind, drawing material from the top downward behind each arm and mixing material vertically as well as horizontally, which is needed when the depth of mix is high. The high speed creates Compulsory mixing action, breaking -up clumps and distributing cement evenly to coat all particles. This creates stronger concrete. Sicomas mixers can receive AND MIX their full rated volume and without any extra mixing time.

How many Sicoma planetary mixers are there in operation?

6000 have been manufactured and there are over 5000 in operation worldwide. No other planetary mixer comes even close to these numbers. In 2006, over 200 have been produced; many more than any other manufacturer. These statistics show that the MAO is truly what it claims to be a great mixer for a great price.

Why does the Sicoma planetary mixer have 3-armed stars while other top mixers in its class have only

Sicomas designers have studied the action of both 2-armed and 3-armed stars and concluded that 3 are better. Not only because there are more arms and blades, but because the blades can be positioned to be much more effective. To start with, the arms can sweep the mixing volume more effectively because the more paths there are, the more times each area can be covered in every minute; this is important because the ARMS do the mixing, the blades giving the fast discharge action. This gives better mixing. Less obvious, however, is the angle of the blade. The combined rotation of star and individual blade across the mixer floor shows that the blades should be angled not at right angles to the star shaft but at a slight inward angle. This gives better sweeping action and eliminates lengthways slicing through the mix, which is ineffective and causes excessive wear. Since the outer edge travels further than the inward edge, it receives more wear. While others add replaceable segments to compens
