Mining & CrushersCone Crusher
Cone / mantle liner (inner crushing surface – rotating cone)
Profile accuracy critical – crushing gap geometry determines product size. Mn steel work-hardens under compressive impact. Mn18Cr2 suitable for harder rock (granite, basalt). White iron: abrasive low-impact ores (silica sand, limestone).
