Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder.gemstone rock raymond mill. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.
The milling of polymers is usually difficult without the use of some liquid nitrogen since many polymers melt in the high energy environment of the mill, especially after a mill has warmed up to its running temperature. The biggest reason, however, is for keeping polymers below their T g.
The influence of ball-mill grinding process parameters and polymer properties on the mechanochemical degradation of amorphous polymers was explored. For process parameters, the grinding frequency was found to have the greatest impact on the degradation rates of polystyrene (PS), with ca. 17 times difference in rate constants between the lowest and the highest frequencies studied.
