Separation Of Steel Dust From Grinding Sludge

Separation Of Steel Dust From Grinding Sludge

Process of separating valuable materials from grinding ...

The ball mill 13 has only a few balls, rods, or other g0 attrition means 14 therein for breaking up the lumps of grinding dusts or sludge. Water is introduced into the ball mill with the grinding dust or sludge through a pipe line 15. A trommel screen 16 is connected to the discharge end of the ball mill 13 and rotates with the ball mill.
