screens and classifiers (for the production of manufactured sand). Some stone crushing plants produce manufactured sand. This is a small-sized rock product with a maximum size of 0.50 centimeters (3/16 th inch). Crushed stone from the tertiary sizing screen is sized in a vibrating inclined screen (fines screen) with relatively small mesh sizes.The second chart illustrates that cement can be used to produce concrete and that the concrete-producing process is much simpler than that of cement alone. The procedure consists only of combining cement, sand, gravel and water in a concrete mixer, and the proportions of each ingredient need to be 15%, 25%, 50% and 10% respectively.Project Summary.
