1. Release the two retaining rods.

2. Move the fixed rod handle to drive the adjusting ring to rotate to adjust the gap. The adjusting ring rotates clockwise, the gap is reduced and the material fineness becomes smaller. Counter clockwise rotation, the gap increases and the particle size of the material is coarse.

3. After the clearance between stator and rotor is adjusted, the two fixed rod handles should be tightened at the same time.

4. According to the particle size and batch requirements of processed materials, the limit screw can be adjusted after selecting the best clearance between stator and rotor.
