How is the jaw crusher specification expressed? How to determine large, medium and small?

The size of the jaw crusher is indicated by the width and length of the mine mouth. For example, a crusher with a width of 600 mm and a length of 900 mm is indicated as a 600 x 900 jaw crusher.

When the width of the ore mouth is greater than 600 mm, it is determined to be large; the width of the ore mouth is 300-600 mm, which is determined to be medium-sized; the width of the ore mouth is less than 300 mm, which is defined as a small jaw crusher.
