The research of process of crushing of polymeric materials
Designs are resulted and principles of work of grinders for reception finedispersed powders of polymeric materials are described. New experimental data on crushing polymeric materials are received. Results of crushing with freezing in liquid nitrogen and without cooling in the air environment are resulted in comparison for different designs of grinders. Experimental data are processed in the form convenient for engineering calculations criterium the equations describing dependence of a degree of crushing from dimensionless criterion of similarity Archimed.
