subject: Introduce Of Environmental Sand Recovery Device [print this page] Ying Yang Jia valley town since ancient times is the royal quarries, sand and gravel production has a long history in recent years with the launching of the infrastructure was infull swing, the rise of mechanism gravel in of Jia valley town, the high profits with the help of sand production, the local people standard of living has improved the living environment is greatly discounted.
Go Jia valley town on the way, we can see that pulling stones, sand truck to and from constantly near the infrastructure used for sand and gravel from the gravel plant business is booming, but it is a mountain, but feel the mountains of fresh beauty, in addition to the roar of the machine is dust enveloped the air.
Production site in a sand and gravel plant, operating workers wore masks, but the clothes on and off the thick layer of dust a long time in such an environment, serious damage to the bodies respiratory, but also the surrounding environment serious pollution of nearby villagers also reflected.
The reason for the quarry in order to save the equipment investment, the introduction of sand production line not only has not dust removal device, and no fine sand recovery, which resulted in serious air pollution, such a situation whether additional equipment or policies to improve ?
Foreign enterprises have long fine sand recovery unit to solve this problem, and present, this device also has a range of applications in the country, but experts say that the use of fine sand recovery sand production line to achieve energy saving and environmental protection quarrying field is at a lot of interest.
"In fact, loss of fine sand, only the loss of production, but also seriously affect thegradation of the sand, resulting in irrational gradation and fineness modulus of coarse, greatly reduces the product quality of the sand the same time, too much fine sand emissions will result in pollution of the environment. "Red Star machine Co., Ltd. gravel project, the responsible person work explained.
In fact, for the mechanism of sand production, the government has long expressly provided, the installation of the sand making production line must have a dust removal device and noise reduction device, but the implementation was not perfect and needed the Government to increase supervision and quarries its own to strengthen environmental protection consciousness.
