Another advantage of using an impact crusher is that it has a relatively low operating cost. The machine uses less energy than other crushers, such as jaw or cone crushers, and its impact force is more efficient at breaking down the material, resulting in less energy waste. However, there are some limitations to the use of impact crushers.
