In a Malvern Mastersier Result Analysis Report of Particle Sie Analyer the D50 is represent as D0.50 D represents the diameter of powder particles and D50 means a cumulative 50 point of diameter or 50 pass particle sie D10 means a cumulative 10 point of diameter D50 is also called average particle sie or median diameter D 4 3 means volume mean diameter and D 3 2 means
Iron ores obtained from different sources differ in their chemical and physical properties. These variations make the process of grinding a difficult task. The work carried out in this context focuses on three different samples of iron ore vi. high silica high alumina low silica high alumina and low silica low alumina. The grinding process for all the three iron ores is carried out
The particle sie distribution i.e. the number of particles of different sies is responsible for important physical and chemical properties such as solubility flowability and surface reaction. In many industries such as food pharmaceutics and chemistry traditional sieve analysis is the standard for production and quality control of powders
