Crushing is typically a dry operation that is performed in two- or three-stages i.e., primary, secondary, tertiary crushing. Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 1020 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.

As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant process design, equipment
Apr 20, 2020 The picture above shows an example of how the crushing plant can be divided into primary, secondary, and tertiary stages. The aggregate produced in a primary crusher is classified using a screen into a 0-20 mm fraction and typically a 20-150 mm fraction. The 0-20 mm fraction contains soil etc. and is generally considered to be of poor quality.
