2. A typical con-
crete 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
INTRODUCTION OF MXER

3. CLASSIFICATION OF THE MXER

4.  Continuous mixers produce concrete continuously
without stoppage till such time the plant is working
.Materials are fed continuously by screw feeders ,
continuously mixed and discharged .Continuous
mixers are used in large works such as dams.
 Batch mixers produce concrete batch by batch with
time interval . they are used in normal concrete
works.

6. 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.

1. Pan Mixers

7. 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.

9. 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
