Diesel cement mixers are an alternative to users especially those operating in regions that lack electricity. It is mobile and very convenient to move from one place to another. Its drum is definitely powered by diesel to rotate in either direction; one direction is for mixing while the other is for discharging concrete.

How it works
The drum’s inner walls are fixed with two different blades. One set of these blades is responsible for dragging the contents upwards and towards the center when the drum is rotating in one direction while the other forces the concrete outwards through the opening once the drum is rotated in the other direction. The spiral arrangement of the blades enhances effective mixing and discharging. Learn details from here: http://www.zzchangli.com/diesel-concrete-mixer.html.

Where it is applicable

Countries with electricity shortage have embraced the use of these convenient mixers in accomplishing several construction projects.

Advantages

Diesel mixers are very reliable and extremely robust. This is because they are not affected by external issues like electricity shortage among others.
They are more economical compared to gas powered mixers since diesel is cheaper and readily available than natural gas.
They have huge capacity suitable for large jobs.
Diesel motors are very powerful and gives a lot of torsion leading to thorough mixing and even aeration.
It is safer to store diesel than gasoline and thus there is less likelihood of causing explosions and flash fires.

Disadvantages

Diesel mixers are very heavy and moving them is cumbersome.
They can be dangerous when misused and thus safety training is inevitable.
Physical strength is required when emptying the drum using its ‘side wheel.’
They require ventilation since dangerous fumes are produced.
