3. What is a pet mill or grinder?
• The history of the crusher goes
back over 50 years. Over time,
there have been improving the
materials, designs and
specialization has emerged as the
type of shredding (wood, paper,
plastic, stone, etc.).. But all the
crushers are based towards the
same goal which is to shred or cut
into small all materials for easy
recycling or disposal.
4. Types of crushers
• Jaw crushers or double acting "Blake“
• Jaw crushers, single-acting
• Primary gyratory crusher
• Trituradoras giratorias secundarias y conos
• Roll crusher
5. Selection of Shredders
When choosing between the two types of
devices, and rotating jaws, there are two factors
to consider:
The maximum size of a fracture fragment
The production rate
6. DESIGN AND SPECIFICATIONS
The creation of this type of machinery began with the need to
combat pollution in the environment, pollute every year
because more and more by the development of products
made of plastic and this is a big problem for society, since all
people when we finished eating a product with this type of
material thrown into the environment.
Techniques.
7. Parts of the mill
Consists of seven parts different from each other,
and with different functions.
• 1 .- TABLE
2 .- DEPOSIT BOX
3 .- ROTOR
4 .- TOP
5 .- ENGINE
6 .- CONTROL PANEL
7 .- DIAGRAM OF FORCE
8. 1.- Table
• This piece will allow the mill pet has greater
stability.
9. 2 .- DEPOSIT BOX
• This is where the material will fall and bruised.
10. 3 .- ROTOR
• This is one of the most important since they
will be responsible for the shredding of the
plastic (PET).
11. 4 .- TOP
• The plastic material come in and fall into the
rotor, through this piece.
12. 5 .- ENGINE
• This is going to be in charge of spinning the
rotor, grind for this plastic material.
13. 6 .- CONTROL PANEL
• To be able to control some basic functions of
the mill, such as on, off, rotor speed, among
others.
14. 7 .- DIAGRAM OF FORCE
• This is the most important piece, as it will with
which we control the control panel functions.
15. Conclusion
• Since the beginning of a project can realize the
importance of plastic grinder for what they serve,
realize that the work can get done faster and
more efficient when crushed plastic.
The use of this machinery is critical for
businesses, that is why this machine was
elaborated in order to have a more efficient
performance for the company and that plastic
garbage cheaper and more effective at the time
of operation for operators safer.
