The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.
Secondary crusher uses standard cone crusher, tertiary fine crusher use short-head cone crusher. The iron is fatal to the cone crusher, so the ore must be removed before enters the cone breaks.

Gyratory Crusher Secondary crushing equipment. After materials go though their first round of crushing, they are fed into a secondary crusher to be broken down further. The average input size for a secondary crusher ranges from …
The crushed ore is then moved by conveyor to the secondary crushing stage. A cone crusher is used here. The ore goes into the cone crusher's feeding system, which usually has a hopper and a feed distributor. The feed distributor ensures an even and consistent flow of material into the crushing chamber. It easily handles the coarse materials.
Superior's Pat Cone Crusher is an American-made, bushing-style rock crusher that sets the standard for productivity and durability. With a lifetime warranty and high-grade, industry-exceeding components, the Pat Cone …
Secondary crushing is the second stage in the comminution process and involves breaking down the material further into smaller pieces that can be handled by the tertiary crushers. The purpose of secondary crushing is …
