The development of gravel aggregate is evolving along with the development of construction and infrastructure technology and the progress of gravel aggregate production equipment technology. Mechanism gravel aggregate is gradually developed by the reduction and ban of the natural gravel. The core technology of the gravel aggregate production is crushing and screening stage. Aggregate is eventually developed into the highly integrated, automated and large-scale modern industry of mine mining, processing, material storage and transportation through the process of rivers and lakes of artificial mining, natural gravel machinery mining and large-scale production of mechanism gravel. In environmental protection aspect, urban construction waste concrete and road waste asphalt concrete are recycled and reused. In terms of energy saving, stone transportation power generation has been widely used. Besides, in the mine restoration, it has met the requirements of green mines and harmonious mining area.

At present, the aggregate industry is in a period of great development which is a serious challenge and good opportunity to the industry and enterprise. Companies of poor equipment, high energy consumption, small scale and extensive operation will be eliminated. On the contrary, enterprises with advanced equipment, environmentally friendly standards, low energy consumption, high production efficiency and good product quality will develop largely.
