Cone crushers resemble gyratory crushers from the technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.
Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm. Thus, the feed to the primary crusher should not exceed 2400 mm. Gyratory …
The ® TC Series cone crusher is the latest iteration of the live-shaft crusher design. This design has been proven to perform in heavy-duty secondary and tertiary crushing applications being tough, reliable, simple to operate and easy to maintain.. Embodying the tried and tested design elements of the original live-shaft cone crushers with added …
Choosing secondary, tertiary and fine crushers Cone crushers have long been the preferred choice for processing of hard or abrasive materials. This category …
In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables. These variables are anything that affect the performance of the equipment. Lets begin with an over view of these two crushing stages. Then describe …
Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to …

uncontrolled and tertiary crushing. Controlled secondary and fines crushing have been given the same code as controlled tertiary crushing (3-05-020-03). Also the controlled fines crushing code should, I believe, be 3-05-020-05, instead of 3-05-020-03. The table below (note: modified from email text message format) reflects how I think the SCC
