Clinkerization - Cement Plant Optimization
Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

When people breathe silica dust, they inhale tiny particles of the mineral silica. Over time, the silica dust particles can cause lung inflammation that leads to the formation of lung nodules and scarring in the lungs called pulmonary fibrosis. This is a progressive disease that normally takes 10–30 years after first exposure to develop.
