The impact value of aggregates was determined by following the TS-EN 1097–2 test standard. A high impact value indicates that the aggregate is low resistance to fragmentation. It is evaluated that materials with an impact value above 35 are very weak, those between 10 and 35 are acceptable, and those below 10 are highly durable [33].

The hardness of the material is typically measured in terms of compressive strength, ie the maximum force that the material can withstand before breaking. Hardness levels can range from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials. The harder the material, the longer it may take to crush.
Vertical shafts impact breaking technology originates from foreign countries, to be exact, is the sand grinding technology of American Bamak Company. Through the introduction of technology in the 1980s and 1990s, it has settled down and developed continuously in China. ... fine grinding sand making and aggregate shaping.
The aggregate shaping process with VSI impact crushers begins with the feed material entering the rotor through a centrally located feed tube. As the rotor spins at high speeds, centrifugal forces propel the material outward, where it encounters the crushing chamber walls lined with durable anvils and wear-resistant liners. This collision ...
