Sep 02 2019 · GYRATORY CRUSHER A gyratory crusher uses a mantle that gyrates or rotates within a concave bowl As the mantle makes contact with the bowl during gyration it creates compressive force which fractures the rock The gyratory crusher is mainly used in rock that is abrasive andor has high compressive strength

The gyratory crusher consists of a long conical hard steel crushing element suspended from the top It rotates and sweeps out in a conical path within the round hard fixed crushing chamber Fig 1311The maximum crushing action is created by closing the gap between the hard crushing surface attached to the spindle and the concave fixed liners mounted on the main frame of the crusher

A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening Gyratory crushers can be used for primary or secondary crushing

The cone crusher is a modified gyratory crusher The essential difference is that the shorter spindle of the cone crusher is not suspended as in the gyratory but is supported in a curved universal bearing below the gyratory head or cone Figure 82 Power is transmitted from the source to the countershaft to a Vbelt or direct drive

GYRATORY STANDARD CONE CRUSHER A cone crusher differs from a true gyratory crusher in the following respects 1 It has a shorter cone 2 It has a smaller receiving opening 3 It rotates at a higher speed about twice that of a true gyratory 4 It produces a more uniformly sized stone CHAPTER 14 AGGREGATE PRODUCTION ENCE 420 ©Assakkaf

The majority of gyratory crushers are used as primaries ie they receive the initial feed from the mine or quarry The same type of crusher with chamber modifications is used as a secondary crusher particularly when following a large primary crusher The finereduction gyratory crusher can also be used for tertiary crushing

The objective of this research was to develop a mathematical model for gyratory crushers to help in the prediction of energy consumption and to analyze dominant parameters that affect this energy consumption The development of a gyratory crusher model was achieved in the following three main stages mathematical representation and coding of the crushing process building an amperage
