ThermalDamage During theGrinding Process. King and Hahn (1986) have summarised how to avoidthermaldamage, they discussed how wheel speed effectsgrindingpower and experimentally found that optimum wheel speed is usually within the range 8000-10000 f.p.m at either sides of this rangethermaldamage is more likely.

A process for reducing the sulfur and ash content of coal comprising: treating coal particles in a hydrocarbon oil slurry with minor amounts of a conditioning agent and water to effect agglomeration of ash and pyritic sulfur mineral matter; separating the agglomerates from the slurried coal particles; and recovering coal particles from the hydrocarbon oil.
The novelprocessof this invention can substantiallyreducethe pyritic sulfur content ofcoalwithout substantiallossof the amount and/or carbon heating value of thecoal. In addition, theprocessby-products do not present substantial disposal problems.
