In the process of ore impact crushing, when the feed sizes are within the four particle-size ranges of −63 + 53, −45 + 37.5, −31.5 + 26.5, and −22.4 + 19 mm, the presence of pyrrhotite reduces the impact crushing effect of the ore; that is, the existence of pyrrhotite has a negative effect on the impact crushing effect of the ore.Web
