A production unit is defined as a machine or larger arrangement used to move, store, separate or crush material in the crushing plant. A production unit can be a crusher, screen, feeder, storage bin, stockpile or conveyor. Each production unit is represented by a model, which can be used to predict the performance of the individual unit.

The iron ore crusher production line is a complex process that involves various types of equipment. The process of extracting iron ore and converting it into usable forms involves a series of crushers, grinders, and separators. Each piece of equipment plays a crucial role in the overall functioning of the production line.

For example, consider a crusher set to turn out a product 70% of which will pass a 5/8″ square opening, and in closed circuit with a screen which is equipped to remove the minus 3/4″ product. The curve shows that approximately 85% of the crusher product will pass the 3/4″ square openings.
