However, according to the current grinding technology, we only need to choose the appropriate equipment and scheme. As long as it is confirmed by tests, granite without radiation can produce gravel.
Under the condition of reasonable production technology, the finished product generally meets the requirements of particle gradation, needle content, mud content, strength, firmness and harmful substance content, and granite macadam is stronger than some soft rocks and is more suitable for high-strength concrete.
The hardness grade of granite is above 6, which is better than ordinary stones and pebbles. It has strong corrosion resistance, stability and wear resistance, and can be made into machine-made sand. Moreover, many cases have proved that the produced sand has good quality, uniform particle size and excellent particle shape, which meets the standards of building sand and can be widely used in real estate, water conservancy and railway construction.
