Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.

The main approach to alleviating the above problem is the utilisation of recycled aggregate concrete (RAC) and its derivatives. As an alternative to natural coarse aggregate (NCA), construction waste is fabricated into a recycled aggregate (RCA) to form RAC through a series of operations (i.e. sorting, crushing, cleaning, and sieving).

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.
