What is limestone mill process? Calcium carbonate makes up the majority of the sedimentary rock known as limestone. It is employed in a number of industrial processes, including those that produce cement, building materials, and soil conditioners.
In order to generate high-quality limestone powder, the milling of limestone must go through a number of phases. Limestone mill process consists of:
- Crushing: Crushers including jaw crushers, hammer crushers, and impact crushers break limestone into little bits.
- Grinding: A limestone mill is used to grind the crushed limestone into a fine powder. Ball mills, vertical roller mills, or roller presses are all examples of mills. To increase its reactivity and decrease its particle size, the limestone is ground to a certain surface area.
- Classification: With a classifier, the ground limestone is then divided into several sizes. Depending on the particular use, the classifier separates the limestone powder into various particle sizes.
- Calcination: Limestone needs to be calcined if it’s going to be used to make cement. When limestone is calcined, a high temperature is used to remove carbon dioxide and change calcium carbonate into calcium oxide (quicklime).
- Hydration: Water is then added to the quicklime to hydrate it, resulting in calcium hydroxide, which is used to make cement and other industrial products.
Overall, the production of high-quality limestone powder suited for a variety of industrial uses involves the difficult and highly technical process of limestone milling, which calls for specialized machinery and experienced operators.
