Both roller crusher and cone crusher are widely used for fine or superfine crushing in the industries of mining, chemical industry, building materials, metallurgy and so on. However, they have difference in crushing raw material.
Cone crusher can crush materials with Moh’s scale in middle and high hardness such as quartz, granite and limestone. While roller crusher can crush materials under middle hardness, such as ore, coal, clinker, ceramic raw material, slag and so on. So under the condition of without considering other situations, if a material is at the middle hardness, it can be crushed by both; if the material is at high hardness, it only be crushed by cone crusher.
You may think cone crusher wins roller crusher. This is inaccurate. Take example of double roller crusher, double roller crusher is designed for crushing low hardness. First, the rollers are composed from wear-resisting chromium molybdenum copper alloy and are heat treated for many times, so its the service life is times of the common high manganese steel. Second, the two rollers run in different speed and clean for each other to avoid the raw materials caking. Last, adopted no-power distributor, the output is more evenly.
