JS1500 concrete mixer is a medium-sized mixer, mainly used in large construction projects, it is very important construction machinery. It is a horizontal shaft compulsory mixer, not only can stir dry concrete, but also to stir lightweight aggregate concrete, is a versatile mixer. During the stirring, the stirring blade to drive the rotary movement of the stirring shaft through the tube material to be cut, and so the extrusion passage and flip stirring to make the material sufficiently intense mixing in the relative movement, so that it has good mixing quality, low energy consumption and high efficiency. Modern construction projects mixer widely used not only to reduce the labor intensity, but also improves the quality of concrete projects on China's infrastructure construction has made great contributions. In the next five-year plan, the state has stepped up efforts to build infrastructure, which is the development of concrete machinery industry is very favorable. The main components of the structure type mixer include: transmission, mixing system, feeding system, unloading system, electrical control system and other components. In this design is primarily designed casing and shaft, also identified feeding, unloading methods and structure of the blade, and some mixer truck parts have been checked, so as to meet the job requirements of different occasions.
