Question: A crushing circuit consists of a primary gyratory crusher located near the pit. This is in open circuit, with the product being conveyed to the processing plant. In the plant this material is then fed onto a screen, with the underflow acting as the feed for the milling circuit. The overflow from the screen (oversized material) then ...

A Gyratory Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory cone crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory cone crushers can be used for primary or secondary crushing. The crushing action is caused by the closing ...

The lubrication of Gyratory crushers may be one of the special problems that the Jaw crusher isn't as readily exposed to. This crusher, because it may be loaded from two sides, often is used in an open pit situation where large ore carriers are dumping directly into the crusher. This means that the machinery is exposed to whatever climate …
