As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces move towards the drive end of the crusher. After passing through the crusher, the product -now at a much-reduced size- is discharged through an opening in the bottom shell.
Hydrocone crusher capacities for open-circuit and closed-circuit operations are listed in Table 28. Data are included for various crusher and product sizes. Crusher Variables. The crusher variables which affect the performance of the cone crusher are discussed in the following paragraphs. Gyrations per Minute.
For finer size products (e.g., -6 mm), a special cone crusher known as the Gyradisc is commonly used. Operation is similar to the Standard Cone Head; however, breakage is mostly by attrition rather than impact.

Crushing is a size reduction process that plays a key role in both mineral processing and crushing–screening plant design. Investigations on rock crushability have become an important issue in ...
Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper.
2 All crushers have a limited reduction ratio meaning that size reduction will take place in stages. 3.2 Operation stages: The operating stages in minerals processing have remained the same for ...
In the mining industry, the size reduction processes of rocks are mainly accomplished by gyratory, impactors (i.e., horizontal and vertical shaft impactors), jaw, and …
Therefore, all rock samples were crushed at the laboratory jaw crusher at the same crushing process, i.e., feed speed, feed size, and closed side setting, until reaching the proper size for ...
Moreover, cone crusher output is greatly improved with increase of base angle of cone. As shown in Table 1, when the base angle of the cone is increased from 40° to 54°, cone crusher output is increased from 650 t/h to 1009 t/h, and the weight percentage undersize passing CSS is decreased from 65.2% to 59.7%. Increasing the eccentricity is ...

How to Select the Correct CONE Crusher SIZING THE CONE CRUSHER. The actual selection of a Hydrocone crusher depends upon the consideration of all the factors outlined above, i.e. feed size, capacity required, product required, and operating conditions. Quite logically, the smallest Hydrocone crusher to do a given job should be selected.
Relation of Bond rod mill work index and crushing work index. Similar to the ball mill work index, the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill …
reducing the size of rock particles. Cone crushers utilize this mechanism and are the most widely used type of crusher for secondary and tertiary crushing stages in both the aggregate and mining industry. The cone crusher concept was developed in the early 20th century and the basic
