grinding aids excellent

In summary a convenient efficient and rapid method was developed for the Michael addition of 1 3-dicarbonyl compounds to β-nitroalkenes in good to excellent yields by a grinding method under catalyst- and solvent-free conditions It was more meaningful to find that quartz sand could effectively promote this reaction by acting as a grinding This project explores the use of grinding aids to control the resulting particle size distribution of calcined clay and limestone It was observed that after grinding calcined clays exhibit a strongly bimodal particle size distribution where the clay minerals concentrate mainly in the finer particle population Particle classification (air
