Secondary Impactor HSI HAZEMAG

Secondary crushing requires a robust, heavy-duty rotor and torsion-free rotor body, to provide a high moment of inertia. The grinding path is designed as a series of impact steps (grinding beams/bars) which ensures limited oversize production, provides an excellent level of control over product grading, and delivers a reliable, stress-free
