Tumbling mills are often taken as the object of optimization studies because The measurements of angles were made through protractors with precision of 0.5 degree. In the ball mill, measurement by MCP resulted in a charge level of 27.0 %. scale, so it does not make sense to estimate an error for the charge surface.
