    Jan 01 2017 · When a highly reactive powder mixture is activated in a ball mill the grain size decreases the chemical components are mixed on an increasingly fine scale and chemically active lattice defects are created. Consequently the initiation and propagation of a self-sustaining reaction becomes easier thus prior mechanical activation promotes SHS. Pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins.
