Also, the coal must be ground sufficiently finely that the ash can be incorporated homogeneously into and react with the raw material feed in the kiln. For coals up to about 15% ash content a coal fineness of about 20% residue on 90 micron: is usually sufficient, but very high ash coals or low volatile coals need to be more finely ground.

A coal testing procedure undergoes mainly two types of testing- Proximate Analysis and Ultimate Testing. The 'proximate analysis' includes the testing of Moisture, Ash, Volatile Matter, Fixed Carbon. The fixed carbon plays an important part in the burning of coal, whereas volatile matter plays a significant part in the ignition of fuel.
Coal fineness is a relative measurement of particle size distribution typically applied to the product leaving a pulverizer. Standardized wire mesh screens are stacked and used to shake down samples.

The aim of DTI Project 226 "Carbon Burnout – Coal Fineness Effects" was to establish good quality plant and rig data to demonstrate the effect of changing coal fineness on carbon burnout in a controlled manner, which can then be used to support CFD and engineering models of the process. The project was designed to achieve this through:
Coal blending technology is commonly used in coal-fired thermal power plant in recent years to ease cost pressures. But thermal power plants still use empirical formula to determine the economic fineness of pulverized coal. This approach cannot change economic fineness of pulverized coal based on the proportion of blending coal timely …

The mined coal contains a mixture of different size fractions, together with unwanted impurities such as rock and dirt. Coal preparation (beneficiation) is the stage in coal production when the mined coal is processed into a range of clean, graded, and uniform coal products that are suitable for the commercial market.
The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as W1. Drop 100 gm of cement in a 90 µm sieve and close it with the lid. Now, shake the sieve with your hands by agitating the sieve in planetary and linear movements for 15 minutes.
