Main technical characteristics of cement mixer
The main characteristics of cement mixer include:
Cement mixer dimensions.
Volume, useful and total mixer
Drive motor power.
Concrete mixer dimensions
The overall dimensions of the concrete mixer are an important indicator in the field of its ability to move from the storage location to the facility and back, mobility, expressed in the ability to quickly move within the site and around the perimeter of concrete work.
The dimensions of the installation must be guided by when choosing a place for its storage. Very often, a significant plus is the availability of the technical ability to quickly disassemble into component parts and assemblies. In this case, the possibilities of transportation and storage increase by an order of magnitude.
VAZ wheels and a primitive hitch make it possible to move such a unit over decent distances with good speed, the question is in the presence of brakes and light alarms
A good solution for large-sized concrete mixers is to equip it with a chassis and a towing device, using which you can carry out any movements using a car.
Important! When purchasing a concrete mixer made in the context of a car trailer, be sure to consult about the possibility of moving such a unit coupled to a car on public roads in order to avoid possible problems with representatives of the traffic police.
Total and useful volume of the mixer
The total volume of the mixer is the passport parameters calculated on the basis of the full geometric dimensions of the mixer chamber. Much more informative for the consumer is the useful volume indicator, which is calculated by the formula: total volume divided by three and multiplied by two + 7% of the product obtained. For example: Vtot. 200l. : 3 x 2 = 134l. + 7% = Vpol. 143hp
Thus, for one cycle of loading and mixing, a concrete mixer with a total volume of 200 liters can produce no more than 145 liters of ready-mixed concrete. Exceeding this standard leads to splashing of the liquid part of the concrete mixture from the mixer, increased load on the bearing assembly, drive and motor, poor-quality mixing of the mass of concrete, especially when preparing heavy concrete on granite crushed stone of coarse fraction.
As a rule, a concrete mixer with a nominal volume of 500 liters and above is a stationary and heavy structure with a solid reserve of rigidity
One more nuance. No matter how good a concrete mixer is, there is a performance indicator that depends on a lot of factors.
So, if you are planning fast-flowing concrete work with a total volume of 10 cubic meters of ready-mixed concrete, the volume of equipment purchased for its preparation should be about 300 liters, based on the passport data for the total, not the useful volume, which will be one third less.
Thus, on average, using a concrete mixer with such parameters, during a work shift you will be able to lay 2.5 cubic meters of concrete with all the necessary accompanying operations and complete the concrete work in 4 days. It is clear that these figures are valid for typical averaged conditions and can fluctuate very often downward.
