Dust control for screening systems is similar to that for crushers, although wet systems are generally not used due to blanking of the screen openings by the wet material. Screens should be totally enclosed, and water suppression systems (when compatible with the process) or dust collection and exhaust systems should be incorporated.
Manufactured Sands. On a large number of crushing operations a crusher dust is often left over as a by-product of the crushing process. Through the introduction of our custom built wet processing plants we can transform this material from a waste product into commercially valuable sand and aggregates with a wide range of applications.
The crusher dust must have no particles larger than 5mm diameter. The crusher dust is to be minimum 100mm thick. It must be mechanically compacted (eg plate compactor), level and flat. A border must be placed around the crusher dust to ensure it does not erode away over time or is undermined by heavy rain or burrowing animals.
