A volumetric mixer is a machine that forms concrete by homogeneously mixing cement, aggregates like sand or gravel, and water. A revolving drum is used to mix the materials in it. Mobile volumetric concrete mixer isfrequently used on construction sites to create concrete and provide employees ample time to use it before it hardens.
What factors should you consider before selecting a volumetric mixer?
A motor, a revolving tank, a dump wheel or tipping handle (on the side) that enables the tank to be tilted, and a strong frame make it. The tank has fixed helical blades that mix the elements together to produce a homogenous mixture. The motor can be electric, combustion, or hydraulic, which is used less commonly.
You must first calculate the volume of material you will require in order to select the appropriate mixer for your project. It’s vital to remember that a tank can only be filled up to 80% of its capacity.
When a producer talks about blending volume, they’re referring to 80 percent of the tank’s volume: don’t get these two quantities mixed up.
You must also consider the frequency of use of the volumetric mixer in your selection criterion.
1. Use only on rare occasions (small worksites):
A 60-liter tank might suffice if you only require it for a single jobsite. For this, opt for an electric volumetric concrete mixer.
2. Use it a lot (medium worksites):
In most cases, a 120-liter volumetric mixer will suffice. You can raise the amount to 160 or 190 liters depending on the magnitude of the work. If you’re working on a jobsite where electricity is guaranteed, an electric mixer is the way to go.
3. Use on a regular or intensive basis (large worksites, professional worksites):
If you need concrete on a daily basis, you’ll need a larger tank, at least 250 liters (to be calculated according to your needs). To avoid power supply issues, utilize a model with a gasoline engine for this purpose.
What Are The Advantages Of Using An Electric volumetric mixer?
On medium-sized job sites, an electric volumetric mixer can be used occasionally or even frequently. They’re usually single-phase 220V with 500 to 1,500 watts of electricity. They are three-phase 380V for more power.
Advantages To Using An Electric volumetric mixer:
There are numerous advantages to using an electric mixer:
- Cheap operating costs: low sale price, minimal maintenance, and no supplies (oil or gasoline).
- They begin immediately, irrespective of the outside temperature.
- They are convenient to use indoors due to their small size.
- volumetric mixers using combustion engines are heavier and less agile.
Technical Considerations When Choosing a volumetric mixer
The following are some minor variables to consider while selecting a mixer:
1. volumetric mixer Drum Volume:
When it comes to choosing it, the regularity of use is a crucial factor to consider. This will determine its drum volume.
2. Power of the volumetric mixer:
The operation is explained by the engine power to drum volume ratio. This means that a sluggish engine will be unable to rotate the drum at the appropriate speed to mix a higher volume of concrete. The mixer will eventually be damaged as a result of this.
As a result, engine power must be determined in advance depending on the proportion to be mixed and the manufacturing time.
3. Mains Power:
Before you buy a volumetric mixer, make sure you know how much power it needs to work effectively. When purchasing powerful drum mixers, it will be necessary to acquire powerful generators in order for them to function correctly.
4. volumetric mixer Drum Rotation Frequency:
The lower the minimum rotation speed, the larger the drum diameter. To produce the appropriate concrete, you’ll need not just the right proportions of concrete, but also the right mixing speed.
5. The volumetric mixer’s Blades:
A stationary or spinning blade can be found in it’s drum. The building mixture becomes more even and faster as the number of blades increases.
6. Additional Wheels:
The addition of additional wheels to the volumetric concrete mixer allows for simple mobility of the mixer around the construction site. To prevent the machine from moving by accident, an additional locking system must be installed.
7. volumetric mixer Noise Level:
Because of the working environment, the machine’s noise level is a worry. To avoid disturbing the neighbors, a mixer that emits less noise is chosen for apartment building construction. A machine that produces less noise can be employed on an outside building.
