— The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms …
produce MS. As usual, the CRF is obtained by crushing rock from quarries. However, the conventional method of crushing produces rock particles with plane fracture surfaces, sharp edges and pointed corners or in other words, rock particles with angular shape. The V7 system by KEMCO uses a crusher called Barmac VSI for size reduction.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more
— Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter — approximately 1.6 tons per cubic meter.
