This paper introduces the dynamics model and mathematical characteristics of the constant difference of overflowing pressure with computerized simulation by power bond graph of the fixed differential relief valve hydraulic system on simplified vertical planetary internal grinder, which puts forth proposals to design hydraulic circuit or component. Simulation shows that, when the load changes more than 50%, the speed of cylinder piston changes less than 0.31%, and the efficiency of the hydraulic system has also been greatly improved, which matches the experiments. It makes certain reference to the design of the hydraulic system in which the load changes large.
