Concrete mixers feature a rotating tank, a motor, a rigid frame, a tipping handle, or a dump wheel (on one side) which allows the user to tilt the tank. The tank includes helical fixed blades designed to mix materials to create a homogenous and high-quality mixture. The cement mixer for sale South Africa motors are either combustion, electric, or hydraulic.
To choose the appropriate cement mixer sale South Africa, it is important to find out what type of concrete volumes you will be needing. The tank can only be filled to 80% as a maximum. When manufacturers mention “mixing volume” it means 80% of the tank’s volume.
When it comes to the selection criteria, you also need to think about how frequently you plan to use your concrete mixer.
– Occasional Use
If you only plan to use the mixer for single worksites (small projects), the 60 Litre tank may be sufficient. For these situations, electric concrete mixers are usually ideal.
– Frequent Use
For medium worksites, the 120 Litre concrete mixers are usually sufficient. Dependent on the job size, the volume can be increased to 160 or 190 liters. If there is electricity available at your worksites, electrical concrete mixers are a preferable choice.
– Intensive Or Regular Use
These concrete mixers are designed for professional and large worksites. If you require a concrete mixer that operates every day, non-stop, you will need a concrete mixer with a tank of at least 250 Litres (which you should work out according to your requirements). In these situations, the combustion engine models are a better option to avoid issues relating to power supply.
Reasons To Choose Electric Concrete Mixers?
Electric concrete mixers are suited to occasional and frequent use for medium-sized worksites. These are generally single-phase 220V that provide power that ranges between 500 to 1,500 watts. Three-phase 380V is a better option when a higher level of power is needed.
Electric Concrete Mixer Benefits
– Budget-friendly selling price, no consumables (gasoline or oil), and just about no maintenance.
– Regardless of the temperature outside, they will start immediately.
– The compact size of these mixers makes them the ideal choice for indoor use.
– They are more maneuverable and lighter than the diesel engine concrete mixers for sale.
Electric Concrete Mixer Drawbacks
– You will need a power supply on-site.
– These machines are not designed for frequent or intensive use.
Reasons To Choose Concrete Mixers With Combustion Engines
Combustion engine concrete mixers are suited for professional and larger construction sites, especially those where the cement mixer will be used just about every day. They are more cumbersome, heavier, and noisier than the electric concrete mixer, but they have many benefits that outweigh their drawbacks.
Combustion Engine Concrete Mixer Benefits
– These machines are autonomous which means they operate on diesel or gasoline, which means they do not rely on electricity.
– Best suited for big construction sites, the combustion engines are usually more robust and more powerful than the concrete mixers with electric motors.
– Long service life.
– Easy to move since they come equipped with road-towable, inflatable tires.
Combustion Engine Concrete Mixer Drawbacks
– Noise levels
– Weight
– Sometimes not easy to start
