-Effective grinding/dispersing with pin/counter-pin turbine agitator at high speeds; -Use of wear-resistance materials (Ceramic, Alloy steel, PU); -Production of micron, sub-micron even nano-particles with narrower size distribution; -Use of small beads 0.1-1.2 mm as grinding media; -Sealless structure, without sealing leakage; -Discharge and beads separation without sieve; -No over- grinding due to on-time discharge of fine particles from the grinding chamber; -Effective energy consumed on mainly grinding coarse particles during the process, and the energy utilization efficiency is increased by > 50%. -Adjustment of temperature by controlling flowrate, especially for thermo-sensitive materials.
