Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
While primary crushers process material from a much larger scale, secondary crushers process material refined to a particular size and shape. The key differences between …
Primary Crusher. There are several primary crushers, including jaw crushers, gyratory crushers, roll crushers, etc. The right one for primary crushing often depends on the material to be crushed, but the reduction …
In most applications, the secondary crusher has a primary target of maximizing the reduction ratio and reducing the top size and F80 for the downstream equipment. However, in some applications, the target can …
Secondary Crushing: To refine the size of the materials from the primary crushing stage. Cone Crusher, Impact Crusher: Usually between 125 mm and 150 mm: Further reduced to 20 mm to 40 mm. The material from the primary crusher is fed into secondary crushers for a more uniform and finer size. Tertiary Crushing
Comparing Primary and Secondary Crushing with Jaw Crushers. Starting with primary crushing, jaw crushers really show their might in breaking down huge chunks. ... Now, when you look at secondary crushing, it's all about finessing materials that have already been roughed up by a primary crusher. This time, the pieces coming in are usually ...
Gyratory Crusher Secondary crushing equipment. After materials go though their first round of crushing, they are fed into a secondary crusher to be broken down further. The average input size for a secondary crusher ranges from 13" to 4" during this stage. Secondary crushing is especially important for making graded material that is going on …
