Thus, a small ball load and a low mill speed are preferable from the point of view of variation in the specific energy consumption with particle load. However, in doing so one has to take in to account the mill production rate also. Reasonably high levels of ball load and mill speed are required to maintain a high production rate.

Jul 04, 2018 · Ball mill load parameters. When maximum and minimum ball sizes are known, it is necessary to define the proportions in which different sizes will constitute the load. Loads can be characterized by two parameters, each one of them contributes in a different way to the grinding process: Unitary weight This parameter is considered in the [.]

Calculation of the power draw of dry -compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
