The primary crusher s function is to reduce the size of the rock or stone for easier handling and transportation The primary crusher is usually a jaw crusher or a gyratory crusher which operates by compressing the material between two surfaces The jaw crusher works by moving the material between a fixed and a moving plate
Gyratory crushers are principally used in surface crushing plants The gyratory crusher Figure consists essentially of a long spindle carrying a hard steel conical grinding element the head seated in an eccentric spindle is suspended from a spider and as it rotates normally between 85 and 150 rpm it sweeps out a conical path within the fixed crushing
A gyratory crusher is a type of crusher that uses a cone shaped crushing head mounted on a spindle to break rock material It is typically used in the aggregate industry where it is used to crush rock and other materials The crushing head is driven by a vertical shaft that rotates within a fixed concave bowl As the rock is fed into the top
Compared to the gyratory crusher the cone crusher is characterized by its higher speed and a flat crushing chamber design which is intended to give a high 911 Metallurgist is a trusted resource for practical insights solutions and support in mineral processing engineering helping industry professionals succeed with proven expertise Cone

Basics of gyratory crushers Gyratory crushers are the initial driving force for the entire mineral processing crushers comprise a spider main frames a main shaft eccentric main drive motor and hydraulic motor driven horizontal shaft a horizontal shaft driven by the eccentric rotation of the gear and then driven by the eccentric portion in a
Gyratory Crusher Vs Cone Crusher Gyratory crushers and cone crushers are important crushing equipment in the mining and aggregates industries They are both used to break down large rocks into smaller ones However there are 4 differences between them a Gyratory crushers are primary crushers that break the largest rocks into smaller pieces
In this paper a DEM model was applied to a copper mining gyratory crusher to perform a comprehensive analysis of the loads in the mantle the crushing torque and crushing power A novel polar
The outstanding advantage of the gyratory crusher is that the crushing wall is large which can reach and sometimes it can be as high as The production efficiency is high and the work is relatively stable Either side can feed ore and can be crowded with ore The particle size of the crushed product is crusher is intermittent crushing and its
Gyratory crushers and cone crushers while looking the same and performing similar duties are two different machines A quick look at a machine will allow you to determine if it is a gyratory or a cone In simple terms if you look at the top of the crusher and it has supporting arms spider arms going out to the centre of the machine normally 2 or 3 it s a gyratory
Crusher Close Side Settings When it is necessary or desirable to operate a gyratory crusher at discharge settings below the minimum standard the safe procedure is to fit the machine with a reduced throw eccentric The crusher manufacturer will be able to advise the operator about these special throws for machines of his make
Gyratory crushers and jaw crushers are both primary crushers in the mining and aggregate industries A gyratory crusher consists of a concave surface and a conical head both of which are made from heavy steel castings The gyratory crusher operates on a principle where a conical crushing head probes within a larger conical shaped bowl
Gyratory crushers are principally used in surface crushing plants The gyratory crusher Figure consists essentially of a long spindle carrying a hard steel conical grinding element the head seated in an eccentric spindle is suspended from a spider and as it rotates normally between 85 and 150 rpm it sweeps out a conical path within the fixed crushing
FULLER® HD gyratory crusher applications G5477HD G6089HD G60113HD GYRATORY CRUSHER Capacities are based on the following assumed feed distributions Maximum feed to the crusher F100 equals 80% of the feed opening size and 80% of the gradation F80 is equal to or less than 50% of the feed top size and F30 is equal to or less than
How Do Gyratory Crushers work The gyratory crusher is a heavy machine consisting of an iron or steel frame with an actuating mechanism and a cone shaped chamber lined with wear resisting plates A steady rest called a spider supports the upper part of the machine The main shaft passes through the eccentric journal at its lower end which
