The different grades of road base materials (G1 to G10) relate to specific proportions of parent and non-parent rock as given in the COLTO specification, and are produced by layering different stone and sand materials on large

Dust suppression a must for quarries

21-01-2014 Dust from quarries tends to be unavoidable, particularly when the weather is very dry. Activities, including the drilling, blasting, loading, hauling, conveying and crushing and screening of rocks all generate dust as does transporting the finished products. According to Sustainable Aggregates in the UK, predicting the level of dust emission is extremely difficult because of the

Environmental GUIDELINE ON STONE CRUSHING plant

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.

Aggregates Industry uses Diesel Generators Rock

It is not uncommon for rock crushers to contain a water system with nozzles to lightly spray the rocks prior to crushing. However, this does not completely reduce production of dust. Movement from a crusher with a larger rock classification to a crusher with a smaller classification, then to the finish pile always results in dust.
