There are certain limits on natural sand resources, and a large amount of exploitation will affect the natural environment for a long time. With the continuous development of economic construction in China, natural sand can no longer meet the diversified requirements of construction sand. The round vibrating screen used in sand making line is mostly used in stone line. For 4.75mm with fine machined sand, the screening accuracy is too poor to reach the standard of use. There are certain limits on natural sand resources, and a large amount of exploitation will affect the natural environment for a long time. With the continuous development of economic construction in China, natural sand can no longer meet the diversified requirements of construction sand. Many round vibrating screens used in sand production line For stone lines , the screening accuracy is too poor for 4.75 mm fine grained sand , and the use standard cannot be reached .
