Understanding Comminution: Compression versus impact crushing
The term 'gentle crushing' may sound somewhat contradictory, but compared with the raw power of impact crushing, compression crushing could be considered a much gentler method – which makes it more favourable for harder, abrasive rocks. If impact crushing is opening a walnut with a hammer, compression crushing is the nutcracker method.
Methods to Reduce Environmental Impact of Concrete
Aggregate Conservation to Reduce Environmental Impact of Concrete It is claimed that in North America, Japan, and Europe, around two thirds of construction and demolition waste are composed of old broken concrete and masonry. If these waste materials are reused as a coarse aggregate, material productivity will improve greatly.
