ABSTRACT

For many products or ore products rigorous demands are made by, customers or beneficiation engineers, on the range and width of the particle size distribution. In order to achieve the right particle size distribution in the production process a laboratory tests are often necessary. Other aspects influencing the grinding process are also discussed. The liberation of ores is a well known example of the dependence of the grinding product properties on the particle size. The optimum grinding media of albite is limited to 9kg, grinding time 9min and filling voids ratio 2:1 to reach liberation size(-0.25+0.045mm).


Keywords: Albite, Grinding, Rod mill, Liberation size
