design parameters for a ball mill in haiti

About this site
Design and operating principle. A ball mill is a hollow drum rotating around its horizontal axis. It is filled with grinding balls (impact elements). As a result of rotation, balls on the internal drum surface lift and then fall down under the gravity action. The source material is permanently fed through one of spigots.

Aug 10, 2017 The value of this parameter for CBM is more than OBM for all tests. The value of each morphological parameters of ground particles using minimum size of ball charge (test 1) are quite equals for both mills. In other words, the effect of mill types on particle shape could be negligible with increasing ball surface area.
