of size reduction methods involved in mineral processing using crushing equipments. Crushing is the first step of mineral processing where the ore/rocks from the mine site is fed into the mechanical
d f = Particle size of feed defined as the sieve size though which 80% of the feed would pass through, µm. d p = Particle size of product, as defined as the sieve size through which 80% of the product would pass, µm. Bond's work index, by definition, is the energy required per unit mass to reduce the particle size from infinity to 100 µm.
Size reduction by crushing has a size limitation for the final products. If we require further reduction, say below 5-20 mm, we have to use the processes of grinding.

1. WHAT IS SCREENING • A method of separating solid particles according to size alone is called screening. • Screening is an operation for separating solids on the basis of size alone. • It refers to the separation of solid materials on the basis of size using screens of known openings.
Barrel Mill. Variously known as a Barrel Mill, a Swing-Mill, a Ring Mill or a Stone and Disc Mill, this highly efficient grinding machine comprises a steel vessel containing a solid steel bar (stone) and one or two steel rings, which oscillate with a rotary motion to grind materials from approximately 10 mm lumps down to powders finer than 50 microns.
Micronisation, using fluid energy jet mills to reduce particle size, has been around since the 1960s and utilised by various different industries because it effectively produces micron-sized particles with narrow size distributions, offers a low or negligible risk of contamination and generates no heat during processing
