Crusher Wikipedia
网页A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore ), so that pieces of different composition

Iron Ore Processing Methods فرابین
网页The ore crushing is usually done in 2 ore 3 steps to obtain a considerable particle size for grinding circuits. In this stage the feed ore is crushed into 30 mm which is suitable for downstream processes. Jaw crushers (step 1), cone crushers (step 2), cylindrical crushers and impact crushers (step 3) are the most used crushers in this section.

网页For example, crushing 2 saphirite ores gives you 2 crushed saph. You need 3 crushed saph to make 2 iron plates. So here, you have a net 4 saph ore (needs 2 to crush) to 2 iron plate ratio. Adding sorting turns into this: 2 ore -> crush = 2 crushed ore. 4 crushed ore -> sort = 2 iron ore, 1 copper ore. Smelting non-crushed ore is a 1:1 ratio, so
