5) Percentage of idling time (the time when the crusher is not in use) etc. Roll Crusher: Not widely used; also being replaced by cone crusher(s). Crushing is conducted by two horizontal cylinders rotating towards each other (See Figure 2). Advantages of Roll Crushers: a) Sticky, wet, clayey, frozen materials can be crushed more easily.

The smaller the output size, the more competitive impact crushers become because their percentage of finished product in the first pass is considerably higher than cone crushers. Combined with an upgrade to wear parts materials, this can allow impact crushers to reach a lower wearcost ratio (per tonne) than cone crushers (see Table 1).

Cone crushers were originally designed and developed by around 1920 and therefore are often described as cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.

Combined with an upgrade to wear parts materials, this can allow impact crushers to reach a lower wear-cost ratio (per tonne) than cone crushers (see Table 1).

The cone crusher can not be restarted immediately when it stops suddenly, so as to avoid secondary damage to the cone crushing production line. First of all, you should find out the reasons for the sudden stop of the cone crusher, there are 5 common reasons: 1. The discharge port of the cone crusher is blocked, too much or uneven feeding will ...

Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
