Concrete Transit Mixer Without Truck is an important vehicle to transport concrete of ready mixed from concrete batching plant to the work sites.  A drum is installed on a chassis of a cement transport truck . The mixer drum is either driven by the truck engine or by a separate power take off device. There are many spiral blades inside the drum. When in the process of mixing and transporting the drum of concrete trucks rotate in one direction, generally rotate as a direction of clockwise (may vary with the manufacturer). The concrete in the drum is pushed towards the bottom of the drum so as to to get uniformity of concrete. While transporting the concrete to the construction site, it is rotating clockwise and keeping the concrete inside constantly stirring. Once concrete mixing transport trucks arrive at the work site to pour the concrete, the drum rotation is reversed to anti-clockwise. Now the blade in the drum pushes the concrete towards the drum outlet, then concrete through the discharging chute flow to the construction site ( The discharging chute could be turned for 180 degree ). Mixing system of transit concrete mixers. Feeding tube, batching plant body, spiral blades and center shaft make up the whole mixing system. The mixer tank is placed on the frame at an angle, one end is supported by bearing pedestal of center shaft, and the other end is supported by two rollers, the outside surface of cylinder is equipped with wave channel.
