Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary crusher. They are widely used for crushing hard metal scrap for different hard metal recycling processes. Pivoted hammers are pendulous, mounted on the horizontal axes symmetrically located along the perimeter of a rotor. Crushing takes place by the impact of material pieces with

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.

The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed. After this step, the concrete is separated out by size.

The use of supplementary cementitious materials (SCMs) to offset a portion of the cement in concrete is a promising method for reducing the environmental impact from the industry. Several industrial by-products have been used successfully as SCMs, including silica fume (SF), ground granulated blast furnace slag (GGBS) and fly ash ( Islam et al., 2011 , Imbabi et al., 2012 ).
