CONCRETE MIXER.
CONCRETE MIXER.
The concrete mixer also is known as cement
mixer is an appliance that combines cement, sand or gravel and water to
form concrete. A revolving drum is used to mix the components. Although
for a smaller mixer, portable machine is used at the construction site
in order to give workers ample time to use before it hardens but mixing
concrete by hand is also an alternative in some constructional sites. It
is usually done in a wheelbarrow. Due to its flexibility at a
construction site, it is easy to install as it creates less noise at is
easily affordable.
Types of Concrete Mixer
Metered Trucks: These trucks mix water with the concrete ingredient
materials at the construction site in order to deliver the amount
needed.
Portable: A small revolving drum is used to mix the component. Due
to the transportation flexibility of this Construction Machine, it
wastes no time at the construction site and gives the workers ample time
to use the mixer formed before it hardens. It either is powered by
electric motor or a gasoline engine.
Trailers: They are considered the small version of a transit mix
truck that is used to supply loads of concrete. They are used at
building material locations and rental yards to transport the mixer.
Self Loading: They are one of the uniquely designed machinery to
transport, mix and batch the concrete. The loading bucket is fitted with
an operator driver cab which is mounted on a rotating drum. The drum is
of tilt/ reversible type or a combination of both. The mixer rotates
within the drum at a speed until the concrete is discharged from the
fitted chute. They are often used for the construction of the high-speed
railway, highways construction, concrete pavement maintenance, bridge
and tunnel construction.
