2. A typical concrete mixer uses a revolving drum to mix the components and prepare uniform concrete. Cement Gravel Sand Water A device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete

3. Mixers fall into Two Categories Continuous Mixers and Batch Mixer Continuous mixers produce concrete continuously without stoppage till such time the plant is working. In this, materials are fed continuously by screw feeders, continuously mixed and discharged. Continuous mixers are generally used in large works such as Dams. Batch mixers Produce Concrete batch by batch with time interval. They are used in normal concrete works. Batch mixers are of two types – Pan mixers and Drum mixers Drum mixer is further classified into – Tilting mixer, Non Tilting mixer and Reversing mixer

7. Pan Type Mixer Pan Mixers with revolving star of blades are more efficient. They are suitable for stiff and lean mixes, which present difficulties with most other type of mixers, mainly due to sticking of mortar in the drum.

9. Type of Drum Mixer Characteristics Non-tilting mixer Single drum rotating about a horizontal axis. Fixed blades work the concrete towards the discharge end of the mixer, in order to provide a rapid rate of discharge . Tilting drum mixer They are most suitable for concrete with large sized aggregate and, since they have a rapid discharge rate, are suitable for low workability concrete. Internal blades lift and tumble the ingredients onto itself . Reversing mixer Rotate in one direction for mixing and in the reverse direction for discharge. One set of blades exists for each operation. Provide efficient mixing with very little build up within the mixer. Are suitable with dry concrete mixes.

18. Transit Mixer Special concrete transport trucks are made to transport and mix concrete up to the construction site, they are called as Transit Mixer. They can be charged with dry materials and water, with the mixing occurring during transport. They can also be loaded from a "central mix" plant, with this process the material has already been mixed prior to loading.  The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery. The interior of the drum on a concrete mixing truck is fitted with aspiral  blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building site.  When the drum rotates in the other direction, it forces the concrete out of the drum.
