In this paper we present a simulation model of grain growth with moving particles in three dimensions using the Monte Carlo method. The effect of concentration and particle size on grain size was studied. In general, it was possible to observe the migration of the particles towards the grain boundaries and the pinningthat they produce on the movement of the grain boundaries. An effect of releasing the grain boundaries from the particles was also observed at long times. The critical radius, where the grains were dragged for each concentration and particle size, was determined. Finally, the relation between the critical radius, the particle size and the concentration of the particles is presented. It was concluded that the critical radius is generally equal to the radius of the sphere equivalent to the volume between the particles.
