In the plastics industry, Plastic granulators play a key role in the production
process. They take scrap material and re-grind the material into fine pieces
that can be re-melted and processes again into finished product. They are used
to split plastic products such as drums, crates, plastic bottles into flakes,
regrinds. Then, these grinds can be sorted, separated, washed and pelletized
before reprocessing.
Plastic Granulator – A necessary tool for recycling
plastic without difficulty
Plastic Granulator is a device that helps to transform plastic
objects into tiny granules through shredding. It can be used to recycle huge
plastic goods and proved to be a success in the manufacturing industry.
Plastics can be used for various purposes and they are cheap, reliable and long
lasting.
On the other side, day to day wastage of plastics can make the
earth sterile. Plastics usage is good when it is used as a medium of storage.
It is known that many huge objects are made out of plastic and it serves as a
multipurpose material. Using large plastic goods is not good as they result in
pollution and can increase global warming. So, it is advisable to dispose large
plastic materials. Therefore, huge plastic materials are processed using
plastic granulator that turns them into small crumbles. So, they can be used as
raw material to make other plastic goods. In this way, plastic can be recycled
and also helps to reduce environmental pollution.
In the 21st century, plastic granulators are used extensively and they
became important devices. They work on electric power just like any other
machine. Spinning of motors can be done with the help of attached motors. When
a plastic object is passed through, it is converted to small granules and hence
they are named as ‘plastic granulators’.
But, they are very expensive and require a lot of maintenance. Small
firms might not be able to choose these tools.
Types of granulators:
There are three types of granulators that are widely used in the
plastic industry.
1) Double Scissor Cut or Double Angle Cut:
Double scissor cut or double angle cut granulator contains
straight rotor knives that are arranged in parallel with the slight angle. We
can notice various degrees of angles when slanted to completely horizontal. It
also includes stationary knives and they are integrated parallel but in the
opposite direction to the rotor blades. Manufacturers prefer double scissor cut
as it’s open design provide ‘true scissor’
cuts with greater precision.
2) V-type Rotor or Chevron:
In these granulators, knives are arranged in V-shape and mounted
in parallel to one another. Chevron granulators are enduring and suit for
injection or extrusion of plastic scrap.
3) Helical Rotor
In this granulator, knives are aligned in helical or spiral
design. These granulators are robust, durable and can withstand higher impact
load. Helical rotors are perfect for shredding thick cross components.
Depending on the usage of these granulators, they will give you
many more years of service. This helps to have a well-tuned engine for several
years. In the long run, you can also save money besides saving recycling
plastic without difficulty!
