Activarea mecanică în câmp electromagnetic

Abstract

There are presented the experimental results of mechanical activation of the mortar mixture components - sand and cement in magneto fluidized layer , which results from the liquefaction of cylindrical shape soft magnetic steel ferromagnetic particles exposed to a rotating electromagnetic field. On the strength of the magneto fluidized layer the ferromagnetic particles effectuate intensive rotational and translational motions. As a consequence of the constrained collision between them and with the device walls happens the grinding of sand and cement particles that fall in the impact region. Mechanical activation of the mortar mixture components occurs by increasing their specific surface after the grinding process and other factors impact. .
