Jun 02, 2017· Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material During the primary crushing operation, boulder size feeds from 20 to 100 in are reduced to secondary crusher sizes of 1 to 20 in or mill feed size of 5 to 3 in
Jaw Crusher VS Gyratory Crusher Performance Different 1 The rotating speed of the movable cone of the gyratory crusher is low, the stroke is small And the ore is mainly crushed and broken and bent The cone crusher has 25 times higher rotating speed and 4 times larger swinging angle than the gyratory crusher, so the ore is impacted quickly
A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 122 (based on Ref ) This type of flow sheet is usually followed when the crude ore contains below 30% iron The number of steps involved in crushing and grinding depends on various factors such as the hardness of the ore and the level of impurities .
