Impact Crushers

Impact Crushing was used extensively after WWII in Germany, to crush the concrete that was in abundance from bombed buildings. The product was then used again as an aggregate to rebuild cities, houses and roads. This concept was then adapted and improved over many years and is used successfully in the Mining and Aggregate industries …

Types of Crushers: What You Need to Know

Impact crushers have a very similar working principle except instead of the rotating parts hitting the material like a hammer, they instead throw the material against an impact plate which breaks it down. They also come in horizontal or vertical shaft configurations depending on the desired output. For more information on impact crushers check ...

Working Theory of Impact Crusher

UNIQUE Brand Impact crusher is the kind of crushing machine which depends on pound. When this impact crusher works, driven by the motor, the rotors revolve in high speed. When the materials get into the machine, it pumps the flat hammers of rotors, then the materials fly to the impact plate rapidly and pumps the flat hammer again, immediately, …
