The second approach to ball diameter calibration is the so-called absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or thread-driven measuring machine is an example of the absolute concept.

Mill construction details. A ball tube mill may be described as a cylinder made of steel plates having separate heads or trunions attached to the ends with each trunion resting on suitable bearings for supporting the machine. The trunions are hollow to allow for the introduction of discharge of the materials undergoing reduction in size.

A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.
