Detail picture:
What is Concrete Grinder?
A concrete grinder is a machine used as a finishing tool. It levels
and smooths out surfaces by the use of rotating discs engineered
with abrasive diamond bits. Concrete grinders come in many
different sizes and are used in various applications.
Hand-Held Concrete Grinders Walk-Behind Concrete Grinders
The selection of concrete grinder is dependent on the job to be
executed and the type of material to be removed. Major
classification of concrete grinders are hand-held grinders and
walk-behind grinders.
1. Hand-Held Concrete Grinders
Hand-held concrete grinders are used to grind concrete surfaces in
corners, tight areas, and areas where pedestrian concrete grinders
cannot easily reach for grinding. The grinding process creates a
considerable amount of mud which is extracted by a shroud and
extraction hose connected to the equipment unit.
2. Walk-Behind Concrete Grinders
The walk-back grinders are big concrete grinders unit that helps
grind concrete onto the body of the floor. Large areas of concrete
will be ground with these machines as they usually exist various
models of walk-behind concrete grinders. The two main categories
are rotary grinders and planetary grinders.
Rotary Grinders
Rotary grinders use a single large pad that spins at high speeds.
Because these grinders have a higher rotational speed and are
heavier, they are great for jobs that require heavy removal of
surface matter. Rotary grinders can also create a better polish on
concrete floors if done right.
However, because they're heavier and have high-speed rotating
discs, they're often more difficult to maneuver. These grinders
take more training in order to operate skillfully. Rotary grinders
can often leave irregular scratch patterns in the concrete if the
operator is not correctly trained.
Planetary Grinders
Instead of only using one disc like the rotary grinder, planetary
grinders make use of multiple pads to get the job done. These pads
spin simultaneously albeit at different speeds. Multiple discs with
different abrasiveness allow a planetary grinder to remove material
and finish a concrete floor at the same time.
Planetary grinders are more lightweight and easier to maneuver than
the rotary grinders. Their design allows the operator to maneuver
in straight lines without having to struggle. Planetary grinders
work great for smaller jobs. They're ideal for jobs that don't
require heavy concrete restoration.
