A concrete mixer is composed of a motor, a rotating tank, a dump wheel or a tipping handle that allows the tank to tilt. The main factor that govern the selection of right concrete mixer is the volume of concrete that is required to be mixed in a single batch. Always keep in mind that the tank of the concrete mixer can be filled with 80 percent of concrete mix. So, when the concrete mixer manufacturer mentions about mixing volume is 80 percent, it means that 80 percent of the volume of the tank. Do not confuse between the mixing volume and the volume of the whole tank.
Technical Factors Considered While Selecting Concrete Mixer
Some small factors that need to be considered while choosing a concrete mixer are:
1. Drum Volume
While selecting a concrete mixer, the frequency of use is an important criteria to be taken into consideration. This will decide the drum volume of the concrete mixer. These include:
Occasional Use of Concrete Mixer
Frequent Use of Concrete Mixer
Regular or Intensive Use of Concrete Mixer
2. Concrete Mixer Power
The ratio of the engine power to the drum volume explains the performance of the concrete mixer. This implies, a weak engine cannot rotate the drum in required speed to mix a larger mass of concrete. This will finally damage the mixer.
So it is required to choose an engine power based on the quantity to be mixed and the production time in advance.
3. Mains Voltage
Always study the required voltage required for the concrete mixer to work properly, before purchasing it. When powerful drum mixers are purchased, it will require powerful generators to work properly.
4. Drum Rotation Frequency
These condition exists in medium worksites. In these worksites, a concrete mixer of maximum 120 litre capacity is generally demanded and sufficient. Based on the size of the job, the volume of the mixer can be increase to 160 or 600 litres.
5. The Blades
The blade in a concrete mixer drum can be either stationary or rotating. More the number of blades, more even and faster is the building mixture.
6. Wheels on the Frame
Additional wheels for the concrete mixer facilitates easy movement of the concrete mixer all around the construction site with ease. Additional locking system must be provided to prevent accidental movement of the machine.
7. Noise Level
The noise level of the machine is a concern based on the working site. A less noise emitting mixer is chosen for apartment building construction to avoid disturbance to the neighbors. For outdoor construction site, a less noise emitting machine can be used.
