A micro-mixer and use thereof for synthesis of barium sulfate particles is disclosed. The micro-mixer includes feeding tubes, reservoirs, a mixing channel, a buffer reservoir and a sampling tube. The mixing channel is made of hydrophobic materials and processed into a spiral structure, in which baffles are set in interval arrangement at both sides of the channel wall. The types of the baffles include leaning-forward baffles, vertical baffles and leaning-backward baffles. Setting the baffles helps produce local secondary flow in the mixer, which enhances fluids mixing process. The micro-mixer is suitable to rapid reactions or precipitation processes, whose reaction time is much less than mixing time, and has broad application prospects in many fields involving mixing reaction such as pharmaceutical and chemistry industry.
A passive spiral micro-mixer with baffles comprising at least two inlet fluid reservoirs, at least two inlet channels, a spiral mixing channel, baffles and a buffer reservoir,
