Understanding Comminution: Compression versus impact crushing
Impact crushing. Impact crushing is essentially like opening a walnut with a hammer – when the hammer meets the shell, the nut instantly cracks into a number of smaller pieces. Mining equipment creates impacts by using a rotor to violently hit and throw rock against the walls of a crushing chamber.

Environmental impact assessment (EIA) of hard rock
Many rock quarries in the study area have crusher units attached to it. The suspended particulate matter (SPM) is generally higher than 600 μg/m 3 in rock quarries operating along with crusher units. Dust is an inevitable outcome of rock quarrying and is one of the most visible, invasive, irritating and potentially harmful forms of pollution.
