The design of the PM-200 Retsch mill provides angular speeds of rotation of the bearing disk and the grinding bowls that are equal in magnitude, i.e. the coefficient k = 1 for this mill. When k = 1, the path of a grinding ball is an ellipse with the axes 2( R c + r ) and 2( R c − r ).
Milling also produces a rough, grooved surface, which will increase the existing pavement surface area when compared to an ungrooved surface. The surface area increase is dependent on the type, number, condition and spacing of cutting drum teeth but is typically in the range of 20 to 30 percent, which requires a corresponding increase in tack coat (20 to 30 percent more) when compared to an ...
