In the last step of the production process of cerium oxide polishing powder, the product is crushed and classified by airflow mill. The results of crushing and classifying will directly affect the polishing effect of the polishing powder. QLM series airflow pulverizer of our company has the advantage of narrow particle size distribution and precise vertex cutting, which is consistent with the requirements of cerium oxide polishing powder grinding and grading. In the actual use of users, the polishing effect is obviously compared with the cerium oxide polishing powder produced by other manufacturers.
Take a large rare earth new materials Co., Ltd. in Gansu as an example, once purchased Sichuan, Shandong, Kunshan, Shanghai and other airflow mill, made of cerium oxide polishing powder and our equipment production of polishing powder gap is obvious. Because the market demand for the product is more strict, the original product has been unable to meet the market requirements, so we ordered a QLM-3.5 type fluidized bed airflow mill and a FJJ-3.5 type horizontal turbine classifier from our company. After practical use, our company's narrow particle size distribution and precise vertex cutting advantages are very obvious. When D50 is equal to 1.4 micron, the maximum particle size is less than 5 micron. Three QLM-3.5 type fluidized bed airflow crusher and one QLM-1 type airflow crusher were additiously purchased.
Since 2003, there have been dozens of customers in Inner Mongolia, Guangdong, Sichuan, Shandong, Gansu and other areas have adopted our QLM series airflow pulverizer and FJJ series horizontal turbine classifier.
Rare earth polishing powder is widely used in glass polishing, which has the advantages of fast polishing speed, strong cutting force, short polishing time, high finish and long service life. It can also change the quality of the polishing and the operating environment. General rare earth glass polishing powder mainly uses rich cerium oxides. Cerium oxide is a highly effective polishing compound because it can polish glass by both chemical decomposition and mechanical friction. The rare earth cerium polishing powder is widely used in the polishing of cameras, camera lenses, TV picture tubes and eyeglass lenses. At present, there are dozens of rare earth polishing powder factories in China, and more than ten of them have a production scale of hundreds of tons. Strong cutting force, short polishing time cerium oxide polishing powder according to the content of cerium oxide is divided into low cerium, middle cerium, high cerium polishing powder, the cutting force and service life is from low to high.
