What is a reverse drum concrete mixer?
All beautiful buildings are made from concrete. It is very useful industrial ingredient that has made possible wonderful architectural structures. So, how does concrete give shape to such magnificent structures?
The difficulty lies in processing it into a usable form and is either done manually or through intelligent machinery, and such machines are called concrete mixers. There are various types of concrete mixers; of which reverse concrete mixer is one of the most commonly used ones.
This type of mixer qualifies as the non-titling category of tilting drum type concrete mixer and has a simple horizontal structure with the drum rotating about a fixed axis. There are 2 opening to the drum, inlet for material on one side and outlet for the discharge of the finished product.
How does it work?
The working principle is pretty simple and construction of these are less complex, but require precise analysis of the quality of the batch needed to be created. There are 2 directions of rotation in the mixer, mixing cycle and the discharge cycle.
When the material is pushed inside the drum via the inlet chute, the direction is as such that the material is lifted and toppled for mixing.
Once the required density and consistency is achieved, the direction of rotation is reversed. The blade arrangement in side is such that it mashes the mixture towards the exit chute and concrete is pushed out.
Features
Certain features of this system include its efficient mixing ability which reduces the build-up left inside the drum and thus low wastage.
It has short processing period but only small amounts can be processed at a time.
There is not much wear and tear in the system as the drum rotates independent of the support structure and has a fixed mounting. Thus there is no excess load on the gear systems. That are brilliant features of drum concrete mixer.
Further, tubes or tyres could be used as supports for the drum and hence lower amount of energy losses and better support in the system.
It can be considered as a low maintenance, but more efficient mixer in its category based on its capacity.
