A very large number of secondary crushers in our present-day plants were originally primary crushers in those same plants. “Secondary” and “second-stage” are synonymous, and are equally good and descriptive definitions. The term “tertiary” has been used rather extensively in recent years to cover not only third-stage crushers, butThe primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.Primary Crusher an overview ScienceDirect Topics

The rock breaks and falls out the bottom. These types of crushers are usually applied as tertiary or quaternary crushers with less than 2” (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very application-specific. They are sensitive to abrasive materialsPrimary vs. Secondary Crushers: While primary crushers are responsible for breaking down larger rocks and stones into smaller particles, secondary crushers are used to further refine these particles into the desired size and shape.

Concrete aggregates properties crushed by jaw and impact secondary crushing
The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms Our last schematic represents a CLOSED CIRCUIT.

Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm The two most common types are horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers are designed for primary or secondary crushing applications and can produce a cubical product with high reduction ratios. They work by using a spinning rotor with large hammers attached to the outer edge.A Comprehensive Guide to Secondary Crusher Types

Crushers and Their Types IspatGuru
Crushers are classified into three types based upon the stage of crushing they accomplish. 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.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.Crushing 101 Different types of crushers for distinctive needs
