Definition of fine grinding. Fine grinding is usually performed in a mill rotating on a horizontal axis and containing balls, rods, or pebbles (grinding media), which serve to grind the ore in the mill. The different mills used in fine grinding are known as ball mill, pebble mill, Hardinge mill, tube mill, autogenous, etc. Ref: Newton, 1.

For very fine grinding (< 10 μm) of dry plant material, we use a device made up of a cylindrical rotor turning at 3,000 − 1 in a stator with a slightly bigger diameter. Rotor and stator surfaces are equipped with parallel corrugations along the vertical axle. Fines are pulled toward the top. Pin mills have two discs equipped with pins that are parallel to their axle. One

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.

The grinding time of the LBM was set by reducing the total RT taken by the blend to get ground in the BBM, since the BBM produces very fine particles for 250% circulating load. The TRT taken in the BBM for the blend sample was considered as reference grinding time for the LBM (ball mill refers to as LBM of size 500 mm × 1000 mm with liners).
