Primary Crushing - Mineral Processing & Metallurgy

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusherPrimary Crusher - an overview | ScienceDirect Topics,In Mineral Processing Design and Operations (Second Edition), 2016. Abstract. Detail descriptions of designs are given of large gyratory crushers that are used as primary crushers to reduce the size of large run-of-mine ore pieces to acceptable sizes. Descriptions of secondary and tertiary cone crushers that usually follow gyratory crushers are also given in detail.NCDEQ - Primary Crushing,The yellow devise is also used to open 'rock jams' in the bin above the narrow opening to the primary crusher. A detail view of rock entering the primary crusher is shown below. The primary crusher crushes more than 1.5 million tons of stone per year. This is enough crushed stone to make 60 miles of road or 5,000 homes.
