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 .
The special straight line screen and probability screen developed by Gaofu Company have greatly saved the equipment quantity and occupation area, improved the screening efficiency to meet the needs of the industry, reduced the investment ratio, reduced the cost of equipment accessories, and solved the difficult problems in the industry.
