The document describes different types of concrete mixers, including non-tilting, tilting, and reversing mixers, highlighting their designs and suitable applications based on concrete types. It also provides specifications for various mixer models, including capacity and output. Additionally, it explains the function of transit mixers, which transport and mix concrete, maintaining its liquid state during delivery.

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

7. 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. 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. 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.
