Dust pollution can easily occur during the production of fine aggregates in sand and gravel plants, and if sand washing is required it can also cause water pollution and other problems. The following measures can be used for dust pollution problems:

Sand and gravel production line dust advisory

First, the production equipment is sealed. Fine aggregate production equipment adopts a fully sealed structure design, strengthen the dust removal design scheme to achieve environmental protection function.

Second, the use of dust collector and fine sand recovery device. Dry sand process dust removal device selection can effectively reduce dust pollution, but also install fine sand recovery device, can effectively intercept the loss of fine sand, but also increase the output of finished fine sand.

Third, install dust emission concentration tester to detect dust emission concentration at any time.

Fourth, adopt hardened road surface and spray cleaning operation. The delivery road surface in the sand yard should be hardened, and there should be spraying equipment, and staff can be organised to spray and sweep at intervals.
