Will a 3 litre soda bottle do for making a ball mill?

I want to make a small enough ball mill, i plan on using 3/4 inch ball bearings but what i don't understand is how a plastic bottle can work for making the likes of aluminium powder (they say it can) because i would have thought it would "give" when the bearings land on the substance being milled, whereas a metal mill would allow the substance to be crushed more no?

But if PVC or plastic can be used, then will my 3 litre bottle do the job?

Thanks.

What is a VPN?

VPN is (Virtual Private Network) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips).
