When the specification and rotating speed of the ball mill are fixed the filling rate of the ball mill is in the range of less than 50 and its production capacity will increase with the increase of the filling rate Therefore the first loading ratio of ball mill should be calculated according to this formula
The grinding process in ball mills and vertical roller mills differ fundamentally In a ball mill the comminution takes place by impact and attrition The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed although the
The drive of the ball mill consists of an induction electric motor twostage gearbox and the pinion gear This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell see Figure 1 taken from 1 Figure 1 Mechanical system of a ball mill
