A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill …

Typically, a peak temperature of 1400–1450 °C is required to complete the reaction. The partial melting causes the material to aggregate into lumps or nodules, typically of diameter 1–10 mm. This is called clinker. The hot clinker next falls into a cooler which recovers most of its heat, and cools the clinker to around 100 °C, at which temperature it can be conveniently conveyed to …

Over 100 locals workers operated the mill, which included a 16-foot-diameter overshot waterwheel, four pairs of grind stones, and eight coal-fired cement kilns. The cement mill was relocated to the berm side of the canal – meaning it no longer got power from the fall of water from the canal. It was most likely converted to steam power as a chimney sits upon the present-day ruins. The mill ...
