Morning house, I'm a final year student of Civil Engineering at one of the Federal Universities in south east.

As it is the custom for final year students to be engaged in projects, a project topic: Using waste glass powder as partial replacement for cement in concrete was proposed. This glass powder is gotten from the crushing/milling/grinding of the waste glass.
Now my project supervisor told us (we are 4 in the group) to go inquire on how to get this waste glass and how to crush it.

From my inquiry, I discovered that waste glass can be obtained from glass manufacturing firms, bottles, construction sites, glass window and door shops, glass food and beverages container, etc., and the crushing by means of a Ball mill, a grinding machine.

Now my question is how I can get access to a ball mill in Nigeria Attached below are pictures (gotten from Google) of this ball mill.
Thank you.

Hello, did u get the ball bill, I also need it
