Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.

The impact crusher is a first- and second-stage crusher in one unit, so you can crush a 600-mm product down to a final product for resale as recycling aggregate. "Our machines are excellent in recycling asphalt, as we can slow down the rotor speed to crush the asphalt, but not the aggregate inside the asphalt, so the material can be reused in asphalt mixing plants, a huge savings on cost."

Crushed concrete aggregates are pieces of old concrete buildings, roads, and other destroyed concrete structures that are crushed in a crushing machine. This crushed material is then washed clean, then broken up into smaller fragments. The fragments are added to other materials, including concrete, to create recycled aggregate.

Crushing in an impact crusher takes place when the stone is struck by the spinning impact bars, and by that stone being flung against an apron. When impact crushing is used, the striking of the aggregate by the spinning rotor’s blow bars knocks off or breaks the elongated fractures. This process is repeated by an impactor in the secondary stage.

The Aggregate Industry (Cement, Ready-Mix Concrete, Asphalt, Crushed Stone, Sand & Gravel), wants to process rock, sand, and gravel into a salable product as efficiently and inexpensively as possible. One such way to process these materials is sending gravel, rock, and sand through an Impact Crusher, which breaks up the material by either striking it with a rapidly moving blow bar or by

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

As the name implies, Impact crushes use impacts to crush material. Instead of applying compression to break the concrete, they use the impact of hammers. A hammer mill or horizontal shaft impactor, break the concrete by hitting it with heavy hammers that are fixed to a spinning shaft. An impact crusher is good to crush softer, nonabrasive materials.
