A concrete mixer is a machine that homogeneously mixes cement, aggregates such as sand or gravel, and water to form concrete. A concrete mixer uses a rotating drum to mix the components. For small jobs, mobile concrete mixers are often used to make the concrete on the construction site and give workers enough time to use it before it hardens.
In order to choose the right concrete mixer for your job, you must first determine the volume of concrete you will need. It is important to know that a tank can be filled to a maximum of 80%. When a manufacturer talks about混合体积, it is therefore 80% of the volume of the tank: don’t confuse these two volumes.
Frequent use（中型工作场所）。这里，120升混凝土混合器通常足够。根据作业的大小，您可以将卷增加到160或190升。如果您在保证通用电力的网站上工作, favor an electric concrete mixer.
Regular or intensive use(large worksites, professional worksites). If you need concrete non-stop, every day, you will have to opt for a larger tank, at least 250 liters (to be calculated according to your needs). For this purpose, use a model with a combustion engine to avoid problems related to power supply.
Low costs: low selling price, virtually no maintenance, no consumables (oil or gasoline).
Thanks to their compact size, they are easy to use indoors.
该y are lighter and more maneuverable than concrete mixers with combustion engines.
该y also have some disadvantages:
You need to have an on-site power supply.
Not suitable for intensive use.
A concrete mixer with a combustion engine is essential for large construction sites where it is going to be used almost every day. They are noisier, heavier and more cumbersome than electric concrete mixers, but they have enough advantages to outweigh their disadvantages:
该y are autonomous: they run ongasolineor柴油机，所以他们不依赖于电力供应。
Longer service life.
Easy to move: generally equipped with inflatable road-towable tires.
What are the alternatives to using a concrete mixer?
该re are other alternatives to buying or renting a concrete mixer. For example, you can have ready-made concrete delivered to you.
A mixer truck with pumpis also a handling vehicle for transporting concrete to remote or hard-to-reach areas. Thanks to its handling device, it can deliver concrete at distances of more than 150 meters while delivering about 20 to 150m3.per hour.
该different pumping techniques include:
活塞泵:活塞和气缸的系统which sucks up concrete, and another system of pistons and cylinders that releases it.
该impeller pump: the compression of a flexible conduit, powered by a rotating part, activates the pumping.
Self-loading concrete mixer
Unlike the mixer truck, which transports concrete that’s been previously mixed in the factory, theself-loading concrete mixer只有在交付网站到达时才混合混凝土。这可以防止干混凝土并提供更好的质量材料。自动加载混凝土搅拌机既有生态又更经济，因为它可以精确地生产每个项目所需的混凝土量。这可以防止浪费昂贵和环保的混凝土。
