Factors To Consider While Choosing Your Mist
Collector A variety of machining processes that
use metalworking fluids generate airborne mists,
which can be harmful. If left unchecked, these
mists can create a dangerous work environment
that can result in serious health problems for
workers. This is why these mists need to be
controlled by facility operators. One best
solution to keep your space safe, and your
business in regulatory compliance, is a
high-efficiency mist collection system. But,
before you purchase an oil mist collector, it is
important to consider a few critical aspects,
some of them being
The kind of machining processes being used What
kind of machining processes are you conducting?
High-speed and high- pressure applications
include cutting, grinding, and drilling while
low-speed and low-pressure processes include
milling, turning, and honing. The type of fluid
being used What type of metalworking fluid are
you using coolant or oil? Coolants are
water-soluble concentrates that provide
lubrication, while oil coolants are non-
water-soluble, and are not mixed with water.
However, the latter is used mostly as a
lubricant, while the former is used primarily for
cooling. The speed of the machine tool The speed
of the machine tool impacts the amount of fluid
that will be expelled during operation. Low
speed with fewer revolutions per minute will
throw off larger droplets, while fast sped with
more revolutions per minute generates
2
smaller droplets. The larger droplets are easier
to contain, while the smaller ones are
aerosolized at a faster rate, making it very
difficult to contain them. The amount of pressure
of the coolant Most machine tool providers
recommend using high-pressure coolants as they
contain few additives and clean the parts during
the machining process, while also resulting in
operators using less product, as these coolants
are delivered at high pressure, straight through
the machine. Nevertheless, this high pressure
causes the water molecules to break apart,
creating many small mist particles. On the other
hand, low pressure machining creates larger
coolant droplets that are easier to filter. This
makes pressure an important consideration in
determining the best collector for your
application. The temperature of the machining
process The amount of heat generated by the
machining process impacts the type of emission
and the collection system required to contain it.
High temperature vapourizes the liquid
particles, turning them into gas, making it
difficult to contain. Processes that generate
lesser heat, on the other hand, dont cause the
liquid to vapourize. The type of filter used With
a wrong filter, the mist collector can lose
airflow, which means that the emission
concentration goes up when you open the door
between cycles, causing the mist to be released
into the environment. Mist then will pass
through the primary filtration and saturate the
HEPA secondary filter, causing a loss in airflow
and efficiency capture too. This makes it very
important to select the right filter material to
handle your specific droplet spectrum. It is
critical to work with an expert in the mist
collection field to be able to choose the right
mist collector for your application. One such
expert is Powertech Pollution Controls Pvt. Ltd.
whose Mistkiller is a trademarked high-efficiency
centrifugal oil mist collector, designed and
developed for the control of most types of mist,
generated by the use of water-based coolants or
water-based liquids.
