Rock Crushing Rule of Thumb

Jaw crusher: feed diameter 0.1 to 1.5m; reduction ratio 5:1 to 10:1; capacity 1 to 300kg/s; Mohs hardness < 9 [reduction by compression]. Gyratory crusher: feed diameter 0.75 to 1.5m; reduction ratio 5:1 to 10:1, usually 8:1; capacity 140 to 1000 kg/s; Mohs hardness <9. More suitable for slabby feeds than jaw crusher. [reduction by compression].

AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training

Gyratory crushers are operated in open circuit. The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1

A gyratory crusher includes an inner and an outer crushing shell. The outer crushing shell has three regions along its axial length including: an inlet region that tapers radially inward from an uppermost first end; a crushing region that extends radially inward from a second lowermost end; and a radially innermost shoulder region that is positioned axially between the inlet and crushing regions.

Types of Rock Crushers | Quarry Crushing Equipment | Kemper

Gyratory Crushers. Gyratory crushers feature a conical head and concave surface (often lined with manganese steel) and break apart material by compression through what is known as eccentric movement. Like jaw crushers, gyratory crushers are often utilized in primary crushing stations, though they may sometimes be used as secondary crushers, as ...

Rock Crusher History

The gyratory principle was the basis of several rudimentary designs, patented between 1860 and 1878, none of which embodied practical mechanical details at least, not in the light of our present-day knowledge of the art. Then, in 1881, Philetus W. Gates was granted a patent on a machine which included in its design all of the essential features of the modern gyratory crusher.

Crushing technology | Technologies | Kleemann

Gyratory crushers differ from cone crushers with regard to their design. In contrast to the cone crusher, which has a fixed shaft on which the power supply unit and the head rotate, the gyratory crusher has a main shaft that can be moved hydraulically in vertical direction on which the head is permanently shrink-fitted.
