Description
ABSTRACT
The main aim of this project is to fabricate a modified Can Crusher machine to reduce the scrap volume and use the Cans so that carrying them to the recycle site becomes easy. Now-a- days, a large number of cans are used in hotels, canteens etc. and a large volume of space is required for storing or dumping the used Cans. This project includes fabrication of a Can Crusher using single slider crank mechanism which will reduce the volume of cans at least 70%. This report demonstrates the necessary modification, calculation, assembling and fabrication of the machine.

1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Aluminum doesn’t occur naturally in the earth’s crust, it has to be extracted from its ore-bauxite which is mined and then smelted in a very energy-intensive process. Although great care is taken to rebuild the land after mining, changes do occur as a result of mining that are detrimental to the surrounding environment. It takes 80-100 years for aluminum can to decompose. Compared to mining and smelting, recycling aluminum drink cans is far less energy intensive. Recycling aluminum requires only 5% of the energy and produces only 5% of the CO2 emissions as compared with primary production. Aluminum cans are one of the easiest materials to recycle. New drinks cans appear on the shelf just six weeks after recycling. A single aluminum can is said to, when recycled, saves about as much as oil as would be poured into it to fill up.
Can Crushers are used in mechanical and allied industries which crush cans made of different materials. The Can Crusher machine is widely used in beverage industries or in scrap dealers’ shop to reduce the volume of the cans. Consequently, it leads to the reduction of the transportation cost. This machine is primarily used to save space and for recycling. It can be placed anywhere. In today’s life most of the food items are packed in cans like cold and warm drinks and other beverages. Commercial establishments like cafeteria and bars, have to deal with leftover cans. Storage of these cans is often a problem and these increases total volume of the trash. Therefore, using can crusher in such places proves to be advantageous.
In this project, we have developed a modified manually operated can crusher that can crush the tin as flat and as symmetrically as possible before landing into the bin. The design is environment friendly and uses simple mechanism. [6]
1.2 PROBLEM STATEMENT
It has been observed that tin cans constitute significant part of garbage at public places. In order to recycle and process these cans their collection and transportation is necessary. This work is on fabrication of a modified tin can crusher. Tin can crusher helps to achieve volume reduction and reduces transportation costs. It is compact in size and can be operated manually by hand. It will help to keep earth neat and clean as the model eco-friendly
The main aim of a can crusher is to smash an empty aluminium can into the smallest unit possible. The main objectives of the project are-
- To fabricate a simple and easy to use modified can crusher machine involving low cost of construction and easily movable from one place to another.
- To reduce the volume of the cans at least 70%.
iii. To modified a single slider crank manually operated aluminium can crusher.
1.4 APPLICATION OF THE PROJECT
This machine can be very helpful in places such as:
- Canteens,
- restaurants,
- bars,
- catering halls,
- cinema halls and
- Recycling plants are places where a can crusher is pretty much a must.
1.5 LIMITATION/PROBLEM OF THE PROJECT
The manually operated models of the research papers the crushed cans need to be removed manually and also new cans need to be placed every time.
Can crusher are the most efficient, convenient, space saving and easy way to reduce your aluminium waste while fulfilling recycling duty. They are convenient, easy to use and environmental friendly.
1.7 SIGNIFICANCE OF THE STUDY
Construction of industrial saw compartment has played a significance role to mankind and industries. The construction of this work helps to carry out effective separation without many problems. It reduces the physical effort required by operators; free him from tediously repeated work.
1.7 SCOPE OF THE WORK
It was observed that there is a need for the aluminum can crusher to be lighter in weight, safe, efficient and stable. Apart from providing stability, the crusher was required to be transported from place to place. Also, easy handling was another important criteria observed. Therefore the following were the objectives of this work:
- It should be non-hazardous to
- It should crush large number of cans in a less
- It should reduce the labour
It should be compact and should not make use of any complex mechanisms
1.8 METHOD OF RESEARCH
The research was done by sourcing information from the library, internet textbooks and from previous or related subject’s projects. Empirical research was also conducted by performing a standard construction of a saw compartment in the workshop. The apparatus for the construction was set up and carried out with all the precautions strictly adhered to.
5.1 CONCLUSION
In this project we carried out the study on the modification of can crushers and the various mechanisms employed. Some of the technological aspects like robust design, volume reduction were successfully implemented. Overall, the project was very enriching in terms of technical fabrication and design process. The current prototype reduces the volume of cans by 65 %. Auto feed mechanism have trouble due to speed which needs some improvement in near future.
As per the above process of talking it in order to reach a decision, we come to an end that to overcome problems in typical can crushers, due to high efficiency, easy to control the functioning and affordable price the put forward for consideration model of manual can crusher is ready to give help and completes all the expectations necessitate in the disposal of cans. Future scope of proposed fact founded work to decrease the pollution
rate, crush the cans without difficulty. It can withstand the vibrations, no hazards from jerk, no special type of instruction required to operate it. In the time following studying this report we will be aware of through observation that, how the manual can crusher will work, and knowing the construction and how a system of parts working together work in the machine. We gain an understanding how the area of study rather than its practical design is possible in experiment. Other can crusher can only crush one can at one time, but this crusher crushes without interruption by automatic feeding of cans from the tray. The cost of machine is less and easy to operate so it affordable for all industry.
5.2 FUTURE SCOPE:
The number of piston cylinders can be increased by introducing a motor to give the power to the shaft. Self regulating feeding mechanism for cans can be bring in to use by using sensors
The currently developed can crusher machine can crush only low strength cans made of aluminum. The machine can be modified to crush cans which are made of medium strength materials.
With automation, the system can become more robust.
