Claim:
1. A method of utilizing a rotatable carrier to generate particles of solid carbon dioxide for introduction into a transport gas flow system, said method comprising the steps of: a. providing a particle generator comprising a first side, a second side, and a plurality of first and second openings, each of said first openings having a respective size which is selectively settable at one of a first size and a second size; b. selectively setting the respective size of at least one of the plurality of first openings at the first size if particles are to be generated from discrete particles and at the second size if particles are to be generated from a block; c. urging one of a block or discrete particles of solid carbon dioxide against the first side of the particle generator; d. rotating the particle generator; and e. generating particles from the second side of the particle generator.
