There are primarily three steps in the process of manufacturing M sand.
Step 1: Crushing
Vertical shaft impact (VSI) crushers first crush stones of different sizes into aggregates.
Step 2: Screening
The aggregates are then crushed into the sand by a Rotopactor to obtain the required grain size.
Step 3: Washing
Last but not least, a screening process is conducted to eliminate dust particles and sand washing to eliminate small particles.
M Sand Advantages and Disadvantages
M Sand Advantages
Man-made sand is very cohesive and compressive. It has fewer impurities, which is best for making concrete of higher quality.
Since the sand is formed from a particular kind of granite, it possesses the right physical as well as chemical properties to be utilized in buildings made of concrete.
There is no waste because there are no contaminants. Moreover, M sand transportation expenses are 30% to 50% lower compared to river sand shipping expenses.
M–sand manufacturing units can be constructed near the point of consumption of the product, which reduces the cost of transportation and maintains a regular supply.
Artificial sand usage eliminates riverbed excavation to obtain river sand, which carries adverse environmental impacts like water scarcity and undermining dam and bridge stability.
Since the angular grain or flaky particles generated by improper crushing might demand more water and cement, making it unsuitable for the formation of concrete.
