clinker

clinker - Hardened, irregular shaped particles of faeces attached to anal hair. Distinguished from the similar clingons and fartleberries by their indurated and dry property. Given enough time, clingons tend to develop into clinkers.

The cement mill

As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further. Grinding systems are either ''open circuit'' or ''closed circuit.'' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product.
