Need help

Hello everyone, I am doing a technical study of a machine for perforating Coca Cola bottles by a rotor with circular blades as part of an end-of-studies project, this machine must tear 1800 bottles of 1 L per day, The compressive strength of PET (Polyethylene terephthalate) = 70 MPa
The tensile strength of PET (Polyethylene terephthalate) = 60 MPa
The crush resistance of PET plastic bottles = 150 MPa
The final shape of the torn bottle is not important, I want to know a clear approach to determine the power of the motor and the dimension of the circular saw blades.
Thank you so much.

Without you taking the time to answer us...

I think it is not necessary to "pollute" the forum with a new similar question.

But this time the information is more precise

Hello

 

There's also no need to send PMs to everyone. (I received one).

 

The goal of your project is to make you think for yourself, not to appeal to the net.
