[learn_more caption=”IMPACT CRUSHERS” state=”open”] A crusher in which the incoming feed drops vertically through the chamber, strikes rotating impeller bars and is then impacted against breaker bars within the chamber. Due to this severe impacting of material, a single impeller impact breaker realizes up to a 20 to 1 reduction ratio. Uses impact to crush material.[/learn_more]
[learn_more caption=”JAW CRUSHER”] A crusher that breaks material by squeezing or compressing it between two jaw plates, one moveable and one stationary. Normally used as a primary crusher. Uses compression and some attrition to crush material. Typical reduction ratio is 6 to 1.[/learn_more]
[learn_more caption=”CONE CRUSHER”] Normally the secondary, but sometimes the primary crusher, for further reducing rock. Because its smallest discharge gap is short the gradation produced is more evenly distributed and it does not make as high a percentage of fines as a shorthead cone. It has a larger feed opening than a shorthead (or fine cone). Uses compression to crush material. Reduction ratio of 6-8 to 1.
