Self-loading mixer
It has a long history, back in the early 1900s, driven by a steam engine concrete mixer drum cartridge has begun to emerge. After the 1950s, reverse the material type and tipping the concrete mixer truck function material type of double cone blender and split drum mixer, etc. have come out and get development. Self-loading concrete mixer mixes the barrel wall radially arranged stirring blades. After the operation, the mixing drum rotation about its horizontal axis, adding mix barrel material, is raised to a certain height blade, falling by its own weight, this cycle of movement, to achieve uniform mixing effect. From a simple fall concrete mixer structure, generally stirred plastic concrete based.
Compulsory mixer
The rise since the early 1950s, has been the rapid development and promotion. First there is the disc vertical shaft forced concrete mixer. This mixer is divided into two kinds of turboprop and planets. After the 1870s, with the application of lightweight aggregate, there has been a circular groove horizontal axis compulsory mixer, which in turn sub-bedroom two-shaft and twin-shaft, both self-loading and forced two stirring characteristics . Its stirring blade linear velocity is small, good wear resistance and low energy consumption, faster development. Equipped with a stir on compulsory concrete mixer mix arm blade shaft barrel, adding mix material barrel, stirring blade strong agitation to form a cross stream. This mixing method than intense way since the fall stirring effect, mainly adapted to mix dry hard concrete.
Continuous concrete mixer
Equipped with a helical mixing blade, a variety of materials respectively Mix after continuous weighing into the mixer, Mixed Concrete outwardly from the discharge end of the continuous unloading.Concrete mixing equipment suppliers This mixer mixing time is short, high productivity, the development of compelling.
With the development of concrete materials and construction processes, and have appeared in many of the new structure of concrete mixers, such as steam heated mixer, supercritical speed mixer, sonic mixer, without stirring blade wobble plate mixer and secondary mixing concrete mixer and so on.
