Seam Welded Cement Mixer The JCB-CM150E 230V Electric Seam Welded Cement Mixer is built for professional use with portability in mind, featuring a robotically welded one-piece chassis, an extra-thick seam welded 134L drum with two welded paddles, and a reinforced boss for heavy-duty site conditions. 100L 'Fast Mix' Capacity Its large 100L working capacity and two welded ‘fast mix’ paddles are powered by a high-torque 550W motor, creating strong mixes of concrete and mortar at 28rpm, which reduces reload frequency and saves time on construction tasks.
