Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING

As a conclusion, the higher the speed of the sets, the higher the products amount produced in desired size range. The high amount of products produced can also be because of the longer duration of the sets in ball milling process. However, the speed has more effects on products produced compared to duration of the sets in this experiment.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
