Rocks are broken into small pieces, in a stone crusher. Crushing of boulders lead to production of large quantity of dust, which tends to float in air and spread in the vicinity of the stone crusher. Aug 07, 2021 Generally the crushers are located in clusters. Stone crushers need electricity supply, manpower and roads for conveying the product material so that majority of the stone crushing clusters are located along the periphery of cities. Most of these units operate for about 10-14 hours a day and some operate around the clock in shifts. The global stone crushing equipment market is expected to witness significant growth over the forecast period. Stone crushing equipment is used to lower the size, or to change the shape of the raw material mix by breaking down the stones into small pieces, so that they are easily differentiated for the proper end use.
