The Difference Between Cement And Concrete - Today I Found OutDec 5, 2011 . This type of cement is typically made by grinding small rock-like bits of sintered line and aluminosilicate minerals into a very fine powder. Its fast drying times combined with its higher compression strength compared to other cements, makes it a great choice for use in concrete, mortar, grout, and stucco.differences between cement mill,Cement Milling - Understanding CementCement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to.

Cement mill - Wikipedia

The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter). Ball diameter.
