Primary crushing (Coarse crushing) Primary crushing, also known as coarse crushing, is mainly used for the initial crushing of large pieces of material, and the particle size of the crushed materials is generally large. In the primary crushing stage, the feed size is about 500 to 1500 mm, and the output size is generally 100 to 350 mm.
The hardness of materials crushed by impact crusher and cone crusher is different. Cone crusher is mainly used to crush some materials with higher hardness, such as granite, basalt, tuff, river pebble, etc. Impact crusher is often used to crush materials with small hardness and brittleness, such as limestone, limestone, etc. 4.

Tooth roll crusher, also known as double roll crusher, is a versatile equipment used for material reduction in various industries. It consists of two cylindrical rolls that rotate in opposite directions, with …
There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which ...
Fig. 13 shows the effect of material strength E 0 on the average steady state throughput of the crusher. As the material becomes harder to break it takes longer for the particles to become small enough to transit the crusher which in turn leads to a monotonic decrease in the throughput. This variation is almost linear with log(E 0). As the ...

Austenitic manganese steel – steel alloyed with more than 10% manganese – is work-hardening. That means that high impacts – like those in a crushing chamber for example – cause the formation of a extremely hard surface layer that is two to three times harder than the rest of the alloy If impacted enough, this results in a hard exterior layer backed by a …
