The pellets are baked hard in a pre-heating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.
vegetation. Through this process, habitats can be altered or destroyed. The quarrying sector's primary impact on biodiversity is through the removal of surface features during the extraction of minerals (BBRC, 2012). One of the biggest negative impacts of quarrying on the environment is the damage to plant
