1.Self falling Drum Concrete Mixer
Self falling Drum Concrete Mixer has a long history, in the early 1900s, drum cartridge concrete mixer that driven by a steam engine has begun to emerge. After the 1950s, material reversing and tipping discharge double cone concrete mixer and split drum concrete mixer have been designed and developed. Self falling concrete mixers adopt radially arranged stirring blades on mixing barrel wall. During the operation, the mixing drum rotated around its horizontal axis, material that added into mix barrel raised to a certain height by the blade, and falling by its own weight, so that the cycle of movement achieves uniform stirring effect. Self falling concrete mixer adopted simply structure, generally used for stirring plastic concrete.
2.Compulsory Concrete Mixer
Compulsory concrete mixer since the early 1950s has been rapid developed and promoted. The first is the emergence of vertical shaft forced concrete mixer. This mixer is divided into turboprop type and planetary type. After the 1870s, with the application of lightweight aggregate, there has been a circular groove horizontal axis compulsory mixer, which divided into single axis and dual axis horizontal mixer and both have the advantages of self falling and forced stirring. Small stirring blade linear velocity, good wear resistance and low energy consumption, faster development. Equipped with a stir on compulsory concrete mixer mix arm blade shaft barrel, barrel material mix was added with stirring blades strong agitation to form a cross-logistics. Compulsory concrete mixer has stronger stirring force than self falling, is mainly adapted to mix dry hard concrete.
3.Continuous Concrete Mixer
Continuous concrete mixer equipped with a helical mixing blade, mix a variety of materials respectively after successive weighed into the mixer, concrete mixing well outwardly from the discharge end of the continuous discharge. This mixer mixing time is short, high productivity, the development of compelling.
