ABSTRACT:
An extremely efficient reduction of ten mesh feedstock to minus 80 mesh fine elastomeric rubber product may be obtained by interconnecting two sequential grinding mills. The first mill is fed a feedstock slurry reaching ten mesh particle elastomers in a transport fluid such as water. This mill is set to produce a minus 30 to 40 mesh in a single pass, preferably by use of a relatively coarse grinding stone producing a relatively high through put. Water or transport fluid is then added to the thirty mesh output of the first state to bring it back to a transportable slurry which is then fed to a second grinding stage set to produce an average minus 80 mesh particle. This can be produced best by a finer grit grindstone and concomitant advantages will occur due to the uniformity of the feedstock and the lack of large particles in achieving a higher through put.
