Recently, river sand resources have become increasingly scarce, and the price of sand and gravel has risen again and again. The price of river sand has been stable at around 40 yuan/ton, but now the price has risen to 130 yuan/ton. The price of Jiangsha is also rising, from 100 yuan/ton last year to about 140 yuan/ton. "Stone tension is normal."      How to alleviate this situation, machine-made sand is very important, but it is well known that * of the machine-made sand production lines are not high-yield, and many small-scale sand production lines have been banned. Jiaozuo Zhongxin has made improvements to this phenomenon and introduced high-yield production lines.
