Collophanite ore was taken in a test to explore the influence of fine particle entrainment content in return sand to grinding on grinding efficiency. It is found that the lower the fine particle entrainment content in return sand, the higher yield of the newly generated particles in the size range of -0.074 mm. Nevertheless, the increase in the yield of particles within the range of -0.025 mm has little to do with the entrainment content in return sand.
