    Particle size enlargement of powders has become a very important process variable. A number of physical properties of powders can be altered to meet specific needs by changing particle size and bulk density.

    Roll compaction is a method of agglomeration which offers some unique advantages: 1. High volume production of granules from 0.2 to 6 mm in size. 2. Controls bulk density and flow properties within the limits of the material. 3. Low consumption of energy. 4. Minimum labor requirements.

    This paper discusses evaluation of powders and the elements of compacting machine designs.
