Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera ...Web

Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.Web

For the torrefaction temperature range of 250 to 290 °C, the specific grinding energy of torrefied pellets was in the range of 4 to 62 kWh Mg −1, and 13 to 116 kWh Mg −1 for torrefied wood chips. Nevertheless, the grinding energy for pellets through the 0.5 mm screen size was only slightly lower than that of wood chips.Web
