Concrete mixers were a revolution to the construction industry. Now the process of manually mixing small batches of non-uniform concrete mix is performed by much more sophisticated machinery that can produce large amounts and with uniform consistency throughout and also in different batches.
Self-loading mixers
Considering some basic type of concrete mixers where the materials are added manually to the drum, this reduces the efficiency of the system and also increases the time taken to produce each batch. But with this improvement to the basic ones, the mixer drum can mix the concrete, while the material for the next batch could be loaded to the chute. Often, self load concrete mixer can tell operators just how much weight of raw materials is being loaded as well as the amount of concrete that is being discharged.

How do they work?
The working mechanism is pretty simple. Here is how most of these self loading mixers work. Material is loaded to the chute. Chute is released and it turns upside down discharging the material into revolving drum. Now the workers can load material for the fresh batch while the mixture is being processed in the drum. In the end of the cycle, the mix is discharged from the drum and then the cycle repeats. This type of mixers can be a combination of other systems to improve performance. Like a self-loading mixer could be coupled with a reversing drum concrete mixer or a stationary type mixer. Thus the advantages of these types can be further enhanced by the features of this mixer. Also coupling of this mechanism is very simple.
Here is a look at some of the benefits of self loading mixers. The mixer helps save time and thus improves efficiency. Larger drums can be used when coupled with other types of mixer systems where loading is a problem otherwise. Reduction in the amount of wastage of material that is generally scattered when manual loading of drum is done. Saving manpower, thus lower labor costs and better efficiency of the human resource. This mixer is the basis for development of much advance type of small cement mixers and thus it has high value for small scale projects till date.
