The materials after the primary crushing often need fine crushing. In generally, the main fine crushing equipments are impact crusher and cone crusher in the stone production line. Usually we use impact crusher to crush the soft rock such as limestone, for the impact crusher can raise the production and reduce the broken segment. We generally select cone crusher for crushing the medium hard rock.
We must analyze the raw materials and understand its properties and then select the suitable crushing equipment. In general we use two broken segments to crush three level coarse aggregate; use three broken segments to crush fourth level coarse aggregate.
Impact crusher is new and high-efficiency ore-breaking equipment. It is promising equipment with many advantages, such as small volume, simple structure, big reduction ratio (up to 40), low energy consumption, great productive capacity, good finished product shape and selective ore-breaking. However, its biggest disadvantages are its vulnerable board hammer and impact board. Especially when breaking hard ores, they need to be replaced frequently. Owing to the appearance of some wear-resisting materials at present, this series of impact crusher has been used in some concentrating plants.
Cone crusher is suitable for the crushing of materials in the industries of metallurgy, building, road paving, chemical and silicate. It can crush kinds of ores and rocks with the hardness of medium and above medium. Cone crushers have the advantages of big reduction ratio, high efficiency, low energy consumption, and equal granule. It is used in the medium and fine crush of all kinds of ores and rocks.
Jaw crusher is one of the most popular stone-crushing equipments in the world; Jaw Crusher is ideally suitable for primary and secondary crushing. The highest anti-pressure strength of crushed material is 320MPA. Our design and production are of high position both at home and abroad.
Roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks in mine selection, chemicals, cement and building materials industrial production.
Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers.
