Solved An ore from a crusher is fed to a screen at 100tph

1.1 Calculate the mass flow rate of the overflow. 1.2 Calculate the screen efficiency based on undersize. Question: An ore from a crusher is fed to a screen at 100tph. The oversize makes up 60% of the feed stream. The undersize goes through the screen at 18tph, making up 60% of the underflow stream. 1.1 Calculate the mass flow rate of the overflow.
