Application of dry laser particle size analyzer in cement detection

The dry laser particle size analyzer is used to detect the cement particle distribution to estimate the rationality of the cement ball mill gradation and process operation parameters.It makes the cement particle distribution reaching the tightest packing, improving the cement strength and the adaptability of cement and admixture, reducing consumption of clinker and cement grinding powder.Dry method of cement Particle determination can reduce the cement production cost, and meet the requirements of carbon reduction.

With the development of concrete technology, customers have higher  requirements for cement performance.The particle size of 3~32um in cement plays a major role in the strength improvement rate.The distribution of each particle size is continuous, and the total amount of cement can not be less than 60%. The particle size of 16~24um is particularly important for the performance of cement, the more the better; The fewer particles larger than 65um, the better, because it has little activity and only acts as a filling material. Generally, the larger the characteristic particle size is, the coarser the grinding product will be. The smaller the characteristic particle size is, the finer the grinding product will be. The best characteristic particle size ranges from 20 to 25um。
