Grinding Mill Surging - Mineral Processing & Metallurgy

The phenomenon of “surging” in a mill is a subject upon which very little has been written; presumably because it is a condition which cannot be tolerated in mill operation and which must be eliminated by variation of some or many of the physical dimensions or characteristics of the mill or mill charge. The phenomenon known as “surging” consists of a pendulum-like oscillation of the ...

Motor soft starter - Wikipedia

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.

A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or axis mill, you can try “Sturz” milling to combat the slow moving tip. See below for details.

Bal-tec - Ball Diameter Calibration

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.
