Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The excavated materials are transported to the crushing ...

The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator. The required size of coal is 80% of 90 μm and less than 2% of 212 μm (Atmaca and Yumrutaş, 2014). Hot air generated in a coalfired furnace or from a cooler/preheater is used for drying the coal in the mill.

History of Indiana Limestone. Even prior to Indiana's admission to the Union in 1816, a lightcolored, finegrained native stone had been used by pioneer settlers for cabin foundations, door sills, milling burrs, and memorials. The stone was quarried with use of long star drills and wedges to separate blocks from the main deposit.
