Gyratory crusher can work continuously, has high productivity and crushing ratio ( up to 6-9.5), working performance is very stable, light vibration.
crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable portions of the processed material fall through the crusher at OSS and this determines the characteristics size of the product. The set of a crusher can be varied in the field and some crushers are equipped with ...
The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
Aug 05, 2021· Gyratory crushers are usually used at the primary stage, while cone crushers are more often used at the secondary and tertiary stages due to their higher speed and ability to produce smaller sized discharge particles. Gyratory crushers utilise oil lubrication to perform several functions.
Jul 26, 2017· Primary and secondary stages involve crushing of coarse materials while the tertiary and quaternary stages involve the reduction of ore particles to finer degrees. Activities at the primary stage will depend on gyratory, jaw or impact crushers. Cone crushers, roll crushers and impact crushers are mostly used at the secondary stages.
A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike and thus generates a higher amount of fine material OMahony 1990. Gyratory crushers work on the same principle as cone crushers Figure 4.4c. ... Gyratory crusher l introduce working principle ...
Jan 01, 2016· Gyratory crushers tolerate a variety of shapes of feed particles, including slabby rock, which are not readily accepted in jaw crushers because of the shape of the feed opening. 5.2. Design of Gyratory Crushers5.2.1. Primary crusher.
Two types of machines are available – Gyramatic 'H' and Gyramatic 'N'. Gyramatic 'H' ate narrow Cone Crusher with large gap which enables them to achieve outstanding performance in crushing large particles with high output. Gyramatic 'N' are flat Cone Crushers designed to produce fine …
Dec 24, 2020· The big particles which are crushed at the top of the jaw move down and are further crushed by jaw movement. The jaw opens and closes 300-400 times per minute. It produces a product of particle size 150-250 mm in size. The most common type of jaw crusher is Blake Crusher. Gyratory Crusher. It looks similar to the jaw crusher.
