Mill (grinding)

Okay kiddo, so have you ever played with a big rock or stone and tried to make it smaller by hitting it with another rock or something heavy? That’s kind of what a mill does! It’s a big machine that grinds up and breaks down materials into tiny pieces.

A mill is like a big blender, but way more powerful. It has big, heavy wheels or rollers inside that spin really fast, and they crush and grind things that are fed into the mill. It can grind up things like grains, like corn or wheat, or even rocks and minerals!

The material that is being ground up goes into the mill through a hole or opening, and then gets crushed and ground into tiny bits by the rollers. These bits can be used to make other things. For example, when you grind up grains like corn, you can use the resulting bits to make flour, which can then be used to make bread or other tasty treats.

Mills have been around for a really long time - even in ancient times people used mills to grind up their food and other materials. Nowadays, mills can be powered by electricity, water, or even wind, but they still work in the same basic way - by spinning very fast and grinding things up into small pieces.

So there you have it, kiddo - a mill is a big machine that breaks things down into tiny bits, kind of like smashing up a big rock with another rock, but on a much larger scale!
