The B8, embodying the leading technology and mature down-the-hole drilling methods of Epiroc Group, is an integrated, high-efficiency multi-functional down-the-hole drilling rig that combines hydraulic, pneumatic, electrical, and reliable structural components. This drilling rig employs a high-power two-stage screw air compressor, demonstrating exceptional performance in blasthole drilling work for quarrying, mining, and road construction in open-pit environments. Operating at lower speeds extends the engine's lifespan, reduces fuel consumption, and lowers operating costs, achieving the ultimate goals of high efficiency, low energy consumption, and cost savings.
