• Core Splitter Machine, used for longitudinally splitting drill core samples into representative halves for further crushing, grinding, and analytical sample preparation of coal and overburden.

• Coal core sample prior to longitudinal splitting using the core splitter machine for representative sample preparation.

• Coal core sample after longitudinal splitting into two representative halves using the core splitter machine, ready for further sample preparation and analysis.

• Coning and quartering operation using a mechanical sample divider to reduce bulk material into representative sub-samples for subsequent crushing and analysis.

• Representative sub-sample obtained after coning and quartering through a mechanical sample divider for further crushing and laboratory analysis.

• Sample pulverization in progress using a vibratory cup mill to produce a fine, homogeneous powder suitable for laboratory analysis.

• Pulverized sample being sieved through a 212-micron sieve to obtain uniform particle size for precise laboratory analysis.
