Pollution caused by fine sand discharge



In order to reduce the dust pollution to the environment, the vast majority of users use wet process to produce. The only difference between the wet process and the dry process is that the washing machine is used in the production line. Although the sand washing machine can remove the impurities in the raw materials of sand and gravel, but also cause serious loss of fine sand (0.16mm). Some production lines or even a loss of more than 30%, this will seriously affect the grain of sand ratio, fineness modulus caused by too large, thereby greatly reducing the product quality; and the excess emissions of fine sand, but also cause serious pollution to the environment.
