Normal Particle Size Distribution Of A Ball Mill Grinding

  • comminution

    comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. in geology, it occurs naturally during faulting in the upper part of the earth's crust.

  • ball milling

    a device used to reduce the particle size of materials, bodies or glazes. a ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them.

    the distribution of particle sizes will vary widely around the geometric mean such that there will be some large sized and many small sized particles. roller mills accomplish size reduction through a combination of forces and design features. if the rolls rotate at the same speed, compression is the primary force used. if the rolls rotate at
