An impact crusher pulverizes rock through violent impacts, and its core components responsible for this task are the hammers and blow bars. These are the interchangeable wear parts that directly transfer kinetic energy from the machine's rotor to the feed material. Hammers are typically used in vertical shaft impactors, swinging freely to strike and shatter rock. Blow bars are massive slabs fixed to the rotor in horizontal shaft impactors, hurling material against the aprons for secondary breaking.
Both are manufactured from ultra-wear-resistant materials like high-chromium steel to withstand extreme abrasion and repetitive shock. The efficiency, product size, and operational cost of the crusher are intrinsically tied to the design and health of these components. As they wear, performance declines. Therefore, selecting the correct hammer or blow bar is fundamental to maintaining optimal crushing capacity and minimizing downtime.
Huihe Miningparts Co., Ltd. specializes in the design and manufacturing of casting wear parts, including grinding balls, ball mill liners, and crushers.
