First, the characteristics of crushing equipment and the status quo Development of crushing equipment, can be roughly divided into three stages, namely, the initial stage, the modernization stage and into the 80’s at this stage. Due to different industrial levels in different periods, different technical and economic conditions, different stages of the grinding equipment has different characteristics. 1. The initial stage of crushing equipment Features: Crushing equipment After a long process of development, appeared in 1806 roll crusher, jaw crusher 1858 came out in 1880 cone crusher put into operation; the nineteenth century, seventy Rod appeared in the era
