Electric or diesel motors are used to drive our impactors. Rotor speeds vary from 300 to 900 RPM depending on the model of the machine and gradation requirements. Due to the true impact principle, 3-Stage impact mechanism and slow rotor speed, it is possible to operate the crusher with minimum wear and power consumption. No grates are used.
