This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The compression strength of the materials to be crushed is less than 320MPA. it can be divided into coarse crusher and fine crusher. It is used widely in mine, metallurgy, construction, road, railway, hydro-electric, and chemistry. It is suitable for the primary or secondary crush of large rock with compressive resistance no more than 320MPa. PE type is used for primary crushing, and PEX type is used for secondary and fine crushing. Features of jaw crusher 1.
