Measuring and control領 the particle size distribution of cement is important both in
order to achieve the desired product performance and to control manufacturing costs.
Historic techniques of sieve and air permeability are still in use, but laser diffraction is
becoming a more popular method to determine the particle size distribution of cement.
The laser diffraction technique is quick, easy, reproducible, and provides a complete
picture of the full size distribution. 新一代的高性能激光粒度分析儀
