JS2000-4000 twin shaft concrete mixer is ideal for mixing stiff-consistency concrete, semi-stiff-consistency concrete, plastic concrete and other kinds of concrete in different proportional ratios.
Features of JS2000-4000 Concrete Mixer:
* This concrete mixer uses high-chromium and high-molybdenum scale boards and stirring pieces, with a long service time.
* Shaft seal is applied with patented air pressure seal, which can effectively prevent the leakage of mortars.
* Opening gates mechanism directed by hydraulic can adjust the opening angle of discharging door in accordance with the need, which effectively prevents overspill while discharging the finished materials into truck-mounted concrete mixers.
