Pharmaceutical Technology: PRACTICAL I : BALL MILLING
In this experiment, coarse salt will be placed into the ball mill. With the aid of metal balls of different sizes, coarse salt will then be comminuting into fine powder where the size particle of salt is determined using sieve nest .Sieve analysis is a method used to determine the particle size distribution of a granular material and in this experiment, the granular material is coarse salt.

Experimental Investigation into the Effect of Ball End Milling
The chemical composition of work material is 51.3% Ni, 20.14% Fe, 18.17% Cr, 4.8% Nb, 3.25% Mo, and balance C. Solid carbide Ti-Al-N coated ball end mill cutters of 10 mm diameter, 10° rake angle, and 30° helix angle with two cutting flutes were used for the experiments. A vertical CNC milling machine (HASS, Model-TM2) was used to carry out the experiments in dry and chilled air environments

Small experimental ball mills can also be completely enclosed in an inert gas glove box. As a consequence, the contamination with Fe-based wear debris can be reduced to less than 1–2 at.% and oxygen and nitrogen contamination to less than 300 ppm. Besides the contamination, long processing time, no control on particle morphology, agglomerates, and residual strain in the crystallized phase
