What happened? Jaw plates which need to change frequently for jaw crusher!
The heavy-duty machines use in the first mechanical stage of comminution are mainly jaw crushers. The pivoted jaw swings around the pivot and makes an impact on the fixed jaw, crushing the fed lumps in the jaw crusher. In order to decrease the replacement cost, choose the right material for your jaw crusher is the first thing. BDI offers more

Crushing | CTP
Industrial crushers reduce the material from very large pieces or blocks to around 10 mm. They operate on different principles, depending on the characteristics of the material (mechanical resistance, abrasiveness, humidity): by compression/crushing (jaw crusher, rotary crusher, cone crusher or roller crusher) or by impact/percussion (impact crusher or hammer mill).
