Which balls are used in Pebble mill?
Pebble Mills are the most popular mill designs – furnished with either of three types of linings or extra heavy chrome manganese steel shell. Lined mills are charged with Flint Pebbles, Porox Balls (Silica based), or Arlcite Balls (Alumina based) and unlined mills use Chrome-Molloy Steel Balls.
Why in ball mill different sizes of balls are used?
Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles.
What is the construction of ball mill?
