Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

Cone Crusher. From the discussion so far it is obvious that two energy factors determine a crusher's productivity: (1) Total power drawn affects the quantity produced of any given size or range of sizes. (2) The energy applied, previously defined as the crusher's Power Rate (kilowatt-hours per ton of feed) will determine the size reduction.
