This peanut butter grinder machine works through different shapes of stator and rotor, the stator and rotor will relative motion at the high speed rolling, when the materials will be grinded at the self-possessed, air-weight, and centrifugal force, when adjusts the gap of the stator, the materials will bear powerful shearing force, friction force, impact force and high-frequency vibration, the material will be crushed and grinded and mixed well, then can get the ideal products.
