Abstract：The effect of internal structure of horizontal ultrafine grinding machine on grinding efficiency was studied。 Through the analysis of the device structure and the test situations， the key factors of effecting the grinding efficiency of the horizontal ultrafine grinding machine were found， that were the difference of the grinding forms in two crushing rooms and the running track of feed materials in the crushing room. The structural optimization improvements for the type of CM51 ultrafine grinding machine were suggested .
