The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. These raw materials are extracted from the quarry by blasting. They are then crushed and
The main raw materials used in the cement manufacturing process are limestone, clay, sand, shale and iron ore. Limestone is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products.
The main constituent of ordinary Portland cement are limestone, clay, iron ore and gypsum. Portland cement with mixed materials has added some active or inactive mixed materials, such as slag, volcanic ash, fly ash, etc., on the basis of ordinary Portland cement.

Hoppers for limestone/ clay/ iron ore serve the purpose of providing a buffer storage for mill feed and a convenient arrangement for feeding to weigh feeders for proportioning purpose. Hoppers used to be designed to hold the requirements of one shift.
Cement is a fine, soft, powdered substance, made from a mixture of elements that are found in natural materials such as limestone, clay, iron ore and sand. When cement is mixed with water, it can bind sand and turns into a hard, solid mass called concrete.
Limestone is used to adjust the lime saturation factor (LSF), and iron ore to adjust both the silica modulus (SM) and alumina modulus (AM). An automatic sampler after the mill takes samples of the raw meal every hour, and then transfers the samples to the laboratory via a duct system.
Concrete vs Cement: What's The Difference? People often use the terms ‘cement’ and ‘concrete’ interchangeably. Which is similar to using the words ‘flour’ and ‘cake’ interchangeably. It’s not the same thing. Cement, like flour, is an ingredient. To make concrete a mixture of portland cement (10-15%) and water (15-20%) make a paste.
