Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within …

The mineral samples were crushed separately by a jaw crusher followed by a roll crusher and screened to collect the particles with a size fraction between 0.6 and 3.35 mm. Then, the collected particles were …
Anyone wondering how Bond ball mill work index compares versus SPI or JK A*b? Well, M. Doll says, several comparisons have been published, such as at CMP 2011 and Procemin 2009 and in general, the Wi_BM is not compatible with the other two because they measure different size classes. The Bond ball mill work index measures …
Chalcopyrite Secondary Crusher.

Gyratory crushers were invented by Charles Brown in 1877 and further developed by Gates in 1881 (they were commonly referred to as a 'Gate's crushers' in the early …
Medium-grade oxides and supergene leachable ores are hauled to a 50+ ktpd primary crusher that feeds screens and secondary crushers with a capacity of 45ktpd. Ore is transported to leach pads by conveyor stacking systems to minimize cost and compaction. ... chalcopyrite ore (typically with lower pyrite and higher acid consumption) and …
Chalcopyrite Ore Chalcopyrite was obtained from an operating plant in Antofagasta, Chile. The sample was initially crushed by a jaw crusher, followed by a secondary and tertiary cone crusher, and it was then dry milled in a ball mill to − 38 + 25 μ m. The mineral particles were reduced in size with a closed crushing and grinding circuit.
Chalcopyrite is an important ore of copper found in a wide range of hydrothermal environments. It is often associated with sphalerite and galena. It oxidizes to form copper minerals such as malachite, azurite, cuprite and tenorite. Copper liberated from the breakdown of chalcopyrite may accumulate in secondary supergene enrichment …

A secondary cone crusher achieves its best work when fines smaller than the desired crusher product are removed from the feed. When a crusher is operating with a full chamber, the nominal top size of the crusher discharge is approximately 1.6 times the Closed Side Setting (CSS) of a top performing secondary cone crusher.

2. Gyratory Crusher A gyratory crusher consists of a movable and truncated conical head and a fixed concave shell, as is presented in Figure 1. The head is integral with the main shaft, and it is covered by an element of wear named mantle. The set of these parts is the main shaft assembly.
We have compiled the trace element concentrations in pyrrhotite, pentlandite, chalcopyrite, and pyrite from magmatic Ni-Cu-PGE ore deposits with the aim of understanding their petrogenesis and whether these minerals can be used as indicator minerals. Among the samples, there are some of the most studied world-class Ni-Cu- (Aguablanca, Duluth, …

Roll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of …
Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for …

The feed size means the biggest piece the crusher can crush. Secondary crushers usually can crush pieces that are 6 to 10 inches big (150 to 250 mm). This shows why crushing things smaller first is important. Making sure the pieces you feed into the crusher aren't too big for it is key to avoid clogging, keep things running well, and not ...
