As Industrial Mixing Equipment, concrete mixer includes the power mechanism connected through a shaft with the drive mechanism and driven by the drive mechanism and the drum, the drum barrel tops set around the roll barrel of the ring gear, the gear provided on the shaft is engaged with the ring gear. The new structure is simple and reasonable with gear and ring gear which can effectively overcome the phenomenon of slippage in the rain and fog weather.
Gravity Type Mixer
It has a long history. As early as the beginning of the 20th century, concrete mixer drum driven by steam engine has begun to emerge. 1950s, reverse type, tipping the feed-double cone blender, and split drum mixer came out and developed one after another. On the inside wall of gravity type mixer, there is radial mixing blades arranged. While working, the drum works around its horizontal axis of rotation by adding the mix barrel materials. The materials are raised by blades to a certain height and then falling down by its gravity. This kind of cycling movement achieves uniform mixing. The structure of gravity type mixer is simple and generally used for stiring plastic concrete.
Compulsory mixer
Rised from the early 1950s, the compulsory mixer got a rapid development and promotion. First here came the disc vertical shaft compulsory concrete mixer. This mixer is divided into the turboprop concrete mixer and planetary concrete mixer. In 1870s, with the application of lightweight aggregate, here came the round slot horizontal shaft compulsory mixer. The round slot horizontal shaft compulsory mixer is divided into single horizontal shaft and twin horizontal shafts which also has the characteristics like gravity falling and compulsory falling. The line speed of the mixing blades is slow with good wear resistance and less energy consumption with faster development. Inside the compulsory concrete mixer drum, there are mixing blades amounted by spindle arm rack. For the materials in drum, by the strong agitation mixing blades, they form as cross materials groups. The kind of mixing method has stronger effect than self-loading stirring way. It is mainly used for mixing dry concrete.
Continuous concrete mixer
Continuous concrete mixer is equipped with a spiral mixing blades. All the materials are sent after weighed into the mixer. The finished concrete mixure is sent out from the discharge end. This type of mixing has short time with high productivity.
