Secondary crusher: 6:1 to 8:1; 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. ... This expression is valid for primary crushers. For secondary cone crushers, the 0.75 value takes a value of unity ...



The secondary crusher is the equipment that reduces the size of the materials further, after they have been reduced by the primary crusher. The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, abrasiveness, and size ...



What are the key types of crushers used in mining? The primary crushers used in mining include jaw crushers, gyratory crushers, and cone crushers. Jaw crushers are used for primary crushing to reduce large rocks, while cone and gyratory crushers handle secondary and tertiary stages. Rollers and sizers are also common for softer ores.

Impact crushers are versatile machines that can handle both soft and hard stones, providing excellent particle shape control. Cone crushers excel in secondary and tertiary crushing, delivering high-quality end products.



In principle, the series can be divided into primary and secondary/tertiary sizers. In the primary crusher, a conveyable product (300 mm) can be produced from the ROM material with a maximum edge length of 2.0 m in one step. In the following crushing stages, the required target grain size can be produced in the secondary or tertiary sizer.

These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size. The output of the primary crusher is fed to a secondary crusher, which further reduces the size of the material.





Secondary sources are not evidence, but rather comment on and discuss previous evidence. Tertiary Sources: Tertiary sources of information provide broad overviews or condensed narratives of topics. They analyze and summarize the information in primary and secondary sources in order to provide background on a idea, event, or topic.



The crushing process is divided into three main stages: primary, secondary, and tertiary.
