Construction Working and Maintenance of Crushers …
Gyratory Crushers Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
P&Q University Lesson 7: Crushing & Secondary Breaking
CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages.
Improved gyratory crushing operation by the assessment of …
This work is based on cone crushers, but the similarities between these types of crushers and gyratory crushers suggest that the results may be transferable to gyratory crushers. ... The gyratory crusher is the main coarse crushing equipment for iron ore [2,3], its performance directly affects the quality and cost of subsequent iron ...
2. GYRATORY CRUSHERS
direction when the crusher is working. The older long-shaft gyratory crusher which has the gear above the eccentric (Fig. 23) has another difference in that the eccentric bearing is supported by a bottom plate A. The majority of the current primary gyratory crushers are the hydraulically supported short-shaft type. Instead of being supported
Development of wear model for cone crushers
The wear model presented by Archard [9] suggests that wear is proportional to sliding distance and applied pressure. In the previous work carried out by the author [10] it was found that wear occurs even if there is no macroscopic sliding motion between rock material and liner. This is the case in a cone crusher where there is no macroscopic …
