Quarries are units where large amount of dust is being produced during the productive procedure. During processing, crashing, fractional division and transfer the dust emission is a significant problem. Techniques such as maceration, in order to suppress the dust emission, are not the most effective ones because they can cause many problems to the machines and also at the quality of the exported product. Usage of de-dusting filters is the most effective and reliable solution against dust suppression. During the initial design extra care must be taken for dust enclosure. This action leads into an effective de-dusting installation with low operative cost.
