How is the cement used in construction produced? What is the raw material? Cement is finely mixed by limestone, clay and iron ore powder in proportion,The mixture at this time is called Raw Meal.Then carry out the roasting,The general temperature is about 1450 degrees,The product after roasting is called clinker.Then grind the clinker with the plaster,Mix in proportion,It is called cement.Production method the production process of Portland cement is representative in cement production,It is mainly made of limestone and clay,Raw materials are made from crushing, ingredients, and grinding,Then feed the mature material into the cement kiln,Then grind the clinker with a proper amount of gypsum (sometimes mixed with mixed materials or additives.Cement production is different with the preparation method of raw meal,It can be divided into two types: dry method (including semi-dry method) and wet method (including semi-wet method.1 Dry production.Drying and grinding the raw materials at the same time,Or the metho
