Stir mixing tube is transferred, a reversal expected. Each tank can be mixed with 350Lconcrete (after absorption of concrete volume), to produce 10-14 million cubic meters per hour. Applies to construction sites, roads, bridges projects and small and medium-sized concrete structures plant. Mixing fixed, it can dig the hole, the hopper be flush with the ground, feed convenience and reduce labor intensity. The machine is a novel structure, with high efficiency, mixing good quality, light weight, form aesthetic advantages, is a more advanced model.
