— In the secondary crushing phase, machines play a crucial role, expertly managing materials from primary crushing. These pieces, usually between 150 to 300 mm, are fed into secondary crushers. These crushers are built to handle these sizes, aiming for a consistent range of smaller pieces. Secondary crushers vary in size and gradation.

 — Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is …

 — The term " secondary crushing " has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.

 — The primary function of secondary crushers is to reduce the size of the material that has been extracted from the primary crusher. The reduction in size allows the material to be processed further and to achieve the desired shape and size of …

The capacity is a function of size and OSS. Manufacturers publish tables of capacity for their crushers of various size as a function of the open-side set. 5.1.1 Cone crushers Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available - standard and short head

Operating Principal. In a cone crusher the stones are crushed with both SPB and IPB as the material moves down through the chamber. The relative amounts of IPB and SPB depends on factors like chamber design, crusher geometry, speed, css, eccentric throw, and others.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
