Due to the rapid development of infrastructure and dwindling resources of river sand, construction field began looking for new sand source from artificial sand. Artificial sand refers to river gravel, pebble and other ore crushed by Jaw crusher, Impact crusher, cone crusher, and then screened by sand vibrating screen system, and ultimately got rock particles with particle size less than 4.75mm.
Compared artificial sand with natural sand, the rough appearance and shape is the main difference. The rough appearance and shape has adverse impact on concrete pouring liquidity, which has a direct impact on the quality of the project. Therefore, the quality of the merits of the points of the artificial sand should be mainly in the appearance of rough shape circularity. The development of the building resulting in a sharp rise in the amount of sand, therefore resulting in greatly increased demand for artificial sand. Artificial sand is also called sand, which comes from rocks and earth excavated from the river, river pebbles after crushing and processing to architectural used sand by impact crusher (also known as sand maker).
In the 21st century, China has become the mining machinery manufacturing country and has got worldwide attention, however, we are not mining machinery manufacturing powerhouse. China's does not has many mining machinery with independent intellectual property rights and high-end technology. We should make a greater contribution to China 's economic construction and social development through independent innovation, digital development, intelligent, ecological and achieve the high-end of mining machinery and major equipment.
