several pieces of equipment ( concrete crusher) or several pieces of equipment always operating together, when operated temporarily at major facilities, are eligible to modify the operating permit under this procedure. c) The temporary equipment must not operate for more than 90 days in any calendaryear.

The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.

Concrete aggregate collected from demolition sites is put through a crushing machine. Crushing facilities accept only uncontaminated concrete, which must be free of trash, wood, paper and other such materials. Metals such as rebar are accepted, since they can be removed with magnets and other sorting devices and melted down for recycling elsewhere.

The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle.
