3. PART I-ABSTRACT
BACKGROUND:
A can crusher is a device used for crushing empty aluminum soda cans for easier
storage in recycling bins. For those who are frequent recyclers, their recycle bins may fill up very quickly.
The can crusher gives extra space by crushing and flattening aluminum cans.
SCOPE:
Design and build a pneumatic system that will function as a can crusher, fed by a
chute and crushing two cans simultaneously. The cans will be packed manually and the system will be
operated by a user. When the system is switched ON and the gate of the chute is opened, the cans will
slide and then will be pushed by an actuating cylinder towards a metal block. When a can is crushed it
will slide through a slot in the bottom and then fall into a collection basket.

As my team and I distributed the tasks, we agreed that I would supervise the project. As supervisor, I
helped design the device as well as perform the required calculations. I also helped in the selection and
purchasing of the components for the pneumatic system. I suggested that my team mates would take
over on welding and fabrication as they are more experienced than me. While Ahmed took the role of
selecting the materials used as he has experience in working in the steel industry.

The can crusher device was designed to operate in ambient
ASSUMPTIONS:
It was assumed that a force of approximately 350N is needed to
crush an aluminum can, therefore we set a minimal force of 1000N (1kN) to crush two cans.
MATERIAL:
Aluminum was used to fabricate the crushing chamber and
crushing plate, while carbon steel was used to build the table and collection basket.
CALCULATIONS:
Given: (Bore Size = 25mm) & (Force required = 1KN) & (Pressure =??)
Using the following equations:
-
V = Area x Stroke Length
It was calculated that a minimum pressure of 2MPa is needed to operate the can crusher.
BUILDING STEPS:
-
5 plates of aluminum were cut, 4 for the chamber walls and 1 for the
crushing plate
Sides of the plates were drilled with threaded holes to fit screws
Openings were drilled into one of the plates to allow the cylinder to fit in
Two of the plates were attached to clamps that could be fitted onto the
table
Pneumatic system was assembled as shown in circuit diagrams (see
appendix)
RESULTS:
The device was tested by connecting it to 2 different compressors. When the
first compressor was connected, the crusher was able to crush two cans with no problems faced. When
the second compressor was connected, the crusher could only crush one can at a time, probably
because the compressor could not supply sufficient pressure. Overall, the device performed well and
met our primary goals.

5. PART III-CONCLUSION AND RECCOMENDATIONS
The end-product of the project had minor deviations from the initial designs. No chute was fabricated
due to the complexity of the fabrication process and the lack of both material and time. No safety
interlocks were added to the system, a double acting cylinder was used rather than a spring-equipped
single acting cylinder and a manual directional control valve was used instead of an electronic solenoid
valve. Nonetheless, the device functioned properly crushing two cans when supplied with the correct
amount of pressure. The main goal of the project was to design and build an environmentally friendly
device that will aid in the packing of recyclable material (in this case aluminum cans) and this goal was
met in our device. The device could be improved by applying the following adjustments:
-
Tilt cylinder 90 degrees so that shorter tubes could be used and to prevent
unwanted bundling.
Add a portable compressor to the table so that the device could be used in
locations where a compressor could not be provided.
Add safety features such as a transparent safety guard and a system that
will not allow the piston cylinder to extract or retract when the guard is not
in place.
