Technical Performance and Appliion of Ball Mill and Rod ...The latter is high. However, due to the high discharge speed of the lattice type ball mill, the residence time of the material in the mill is short, the product size is relatively coarse, and the suitable milled product has a particle size of mm or mm. The mass fraction is 45%. 65%.
LAB REPORT SIZE Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by a few factors. The residence time of the material in the mill chamber. The size, density, and the number of the balls. The nature of the balls (hardness of the grinding material).
Use of the attainable region method to simulate a full ...This allowed the appliion of the AR methodology to be extended to a fullscale ball mill. Then a link was established between residence time to mill product specifiions for a given feed size. The findings showed that the residence time required by a fullscale mill falls between those at which the fully mixed and the plug flow mills operate.
Factors Affecting Ball Mill Grinding Efficiency · a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for ...
