Secondary Crushing Equipment - Mineral …
Secondary Crushing Stage. The simplest form of secondary crushing stage involves a single crusher, taking its feed by gravity flow direct from the primary with no interposed scalping separation. This is tantamount to making the over-all reduction in one machine, except of course that there will always be a certain amount of surge capacity between the two crushers. This type of installation has been used in …
SHEDDING LIGHT ON SECONDARY CRUSHING B. Putland,
Secondary crushing of the SAG mill feed is undertaken to increase SAG mill power efficiency, thus allowing higher throughput in existing circuits. Its application is best retro fitted to Brownfield operations where the benefit gained for capital expended is excellent. The implementation of partial and total secondary crushing increases
Evaluation of secondary crushing prior to SAG …
The concept was developed to supplement the feed to the existing pebble crusher with a secondary crusher. Models of this process looked favorable so a portable crusher was installed to test the process. The temporary crusher was successful at increasing the throughput by 7% and based on the operating data, plans are currently being developed to install a permanent secondary crushing system in front of the SAG …
SAG Circuit Design - Crushing, Screening & …
Apparently, secondary crushing before the SAG diminishes the grinding power consumption but, the high participation of the fine particles will deteriorate the grinding efficiency and the power consumption will be higher. In addition, the fine particles will be recirculated and the result will be the power consumption increase. I met, during my operational and consulting experience the both comminution arrangements, but the selection of optimal scenarios …
New Secondary Crushers Concentrate on Higher …
The XL2000 cone crusher is intended for secondary or tertiary applications and does not replace the need for a primary gyratory or jaw crusher. However, the XL2000 can replace a SAG mill, according to the company, thereby reducing overall costs while still maintaining circuit capacity and producing a product crushed to specific requirements.

Crusher - Wikipedia
Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical …

The common secondary crushers are cone, roll, and impact types. The cone crusher (Fig. 13.12) is very similar to the gyratory type, except that it has a much shorter spindle with a larger-diameter crushing surface relative to its vertical dimension. The spindle is not suspended as in the gyratory crusher. The eccentric motion of the inner crushing cone is similar to that of the gyratory ...

and tertiary circuits. 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:
