Abstract：With the adoption of pulverization principle of shearing, DG series of double-refiner discs grinding machines were developed. The machine featured unique structure consisting of double groups of kinetic disc and static disc together with simple and effective system of clearance regulation. Both the function of key parameter，the clearance ΔH between kinetic disk and static disk，the factors influencing the quantity and granularity of powder making were analyzed. The related parameters were reasonably selected.
