A vanadium mine in Shangluo, 500t/d vanadium tailings, with a concentration of 25%, the grain size is about 70% of the 100 mesh, and more than 95% of the dry ore can be extracted with dry row sieve. The tailings of the tailings after dry row are less than 20%. tailings, and the tailings are used for building materials and the tailings are reused; the bottom current can be returned to water resources directly, and the tailings are not used completely.

Shandong Yuanyou heavy Industry Technology Co., Ltd (Yuanyou heavy Industry) was established in December 2000. It mainly produces HZS series concrete mixing plant, HLS series concrete mixing station, LB series asphalt mixing station, WCQ series stabilized soil mixing station and HBT series concrete conveying pump. Concrete mixing truck, pile machinery and other construction machine products.

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 timeWith 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 4.75mm with fine sand, the screening accuracy is too poor to meet the standard.

Before the use of ordinary straight screen, a single unit processing capacity per hour a few tons, far from the screening requirements, not enough for the sand machine processing capacity. We designed 4 mesh -16 mesh for the customer to use the probability sieve to carry on the classification the remaining small part finished product to carry on the subdivision with the straight line screen, has saved the equipment investment at the same time has achieved the enhancement screening efficiency.
