Primary Crushing with Mobile Impact Crushers: Setup, Feed and Wear Parts
Mobile horizontal shaft impact (HSI) crushers are a popular choice for primary crushing in recycling, demolition, and many aggregate operations. One machine can take material straight from the pile and turn out a well-shaped, specification-grade product. Primary duty is also the hardest work an impactor does. Large feed, tramp metal, and high impact loads put the rotor and wear parts under constant stress. This guide covers when a mobile impactor is the right primary crusher, how to set it up for steady production, and how to choose wear parts that hold up.
