Stone crushing is generally divided into several stages?
In the process of breaking, in order to avoid the crush and reduce costs, efforts must be made “without extra pointless broken.” To be very large-grained minerals, crushing to the desired degree of fineness, it is impossible, must be carried out piecemeal.
Concentrator, generally uses two-stage or three-stage crushing. According to the crushed product size difference can be broadly divided into:
1) coarse: 1500~500 mm size, broken into 400~125 mm;
2) pieces: 400~125 mm size, broken into 100~50 mm;
3) fragmentation: 100~50 mm size, broken into 25~5 mm;
