Highway construction cannot get rid of the amount of sandstone aggregate being supplied, and the natural sandstone aggregate cannot satisfy the whole market demand anymore. The main materials used in the road construction mainly include two types: sand and gravel, and gravel is the aggregate of all kinds of concrete, and those whose granularity is bigger than 2mm is being called gravel, and those whose granularity is between 0.074 to 2mm is being called sand. Sand is the main materials of cement mortar, brown cement concrete, asphalt concrete and tar sands, and the main source of sand is the natural sand and artificial sand. The quality of artificial sand is higher, which cannot be limited seriously by the natural environment, so that is the reason why it is becoming more and more popular in recent days.
Sand production line with high efficiency and energy saving is the source of those excellent sandstone aggregate, and the high efficiency tertiary crusher, as the core equipment of crushers, makes a big difference in sand production line, which cannot be replaceable in this process. Sand manufacturing industry has become one gold field on the strong support from our state influenced by the largest investment on road construction.
Henan hongxing mining machinery, as one of the most famous mining equipment manufacturers, can provide the complete sand production equipment, design the jobsites, install the equipment and train the employees at the same time. Sand making machine researched by our company is one new generation type sand maker with the international advanced level, whose performance characteristics can make a big difference in those crushers.
