The peanut butter grinder machine is determined by the geometry, different rotor rotating in high speed under the relative motion, obtained by shearing, crushing, grinding and high frequency vibration. The crushing chamber is provided with three grinding zone, a grade for coarse grinding, fine grinding area as two level, three level for the attritor area, through adjusting the stator and rotor, can effectively achieve the required a superfine crushing effect (or cycle). This machine has the characteristics of compact structure, smooth running, low noise, corrosion resistant, easy cleaning, convenient repair. Is currently the most ideal equipment in the wet ground.
