During the sand-making process, the stone powder produced by means of a vertical shaft impact (VSI) crusher affects the sand quality and pollutes the environment. This paper focuses on experiments and simulations with a stone powder separator (SPS) that is installed in a VSI crusher.
Bond's impact method comes from a double mirrored pendulum impact crusher test on <76mm but >51mm (3″ and 2″) square rock pieces. The resulting consumed power is calculated using Bond's standard equation. See how BWi relates to Ai. A Crusher' Settings 3 main parameters are changed to obtained a targeted P80 product size:
