CementRaw Materials Handling & Crushing
Hammer crusher hammer / beater (limestone, clay, shale)
Cement raw material crushing: limestone (soft-medium), clay (soft), shale (medium). Mn steel suitable for most; Hi-Cr for high-silica abrasive feed. Pin hole geometry: matched to rotor disc. Weight-matched sets for rotor balance.
