The vertical shaft impact crusher (or VSI) has a rotating shaft that runs vertically through the crushing chamber. In a standard configuration, the VSI's shaft is outfitted with wear-resistant shoes that catch and throw the feed stone against anvils that line the outside of the crushing chamber.

As the first stage in a crushing circuit, primary crushing reduces material to a size and shape that can be handled by a secondary crusher. Typically, the minimum setting on most primary crushers is about 4 in. to 6 in. Jaw, gyratory and impact crushers are most often appropriate as primary crushers, although there can be overlap between ...

After the drilling process, the quarrying operation progresses to the extraction stage. Hand quarrying involves the use of specific tools to cleave, split, or break the rock into manageable pieces. These tools include hammers, chisels, wedges, and pry bars, which are leveraged to dislodge and separate the stone from the quarry wall.
In spite of its contribution towards development, quarrying is also responsible for several negative environmental and socio-economic impacts, particularly when quarrying activity is carried out ...
