【Abstract】 Objective To study the feasibility of the preparation of oyster shell ultra-fine powder by airflowgrinding. Methods An orthogonal experiment was used to optimize the grinding process of oyster shell by taking feed-ing particle size, feeding speed, grinding pressure and grinding times as influencing factors and powder yield and aver-age particle size as indices. The experimental results were analyzed by matrix analysis method. Results Optimumgrinding process was as follows: feeding particle size 100 mesh, feeding speed 210 V, grinding pressure 0.6 MPa andgrinding 6 times. The average powder yield was 94.9% and particle size was 2.448 μm. Conclusion The particle sizeof oyster shell ultra-fine powder obtained by airflow grinding was uniform and met the requirement, so it can be promot-ed as the technology of ultra-fine grinding for oyster shell.
