The introduction of drum life

The introduction of drum life Concrete mixer drum life is an important maintenance cost in the industry, in order to improve the life/load through the carbon fiber drum tap, but the cost is increased.Traditional concrete mixer drum the thick is 3/16 " steel plate AR-200 in the new concrete mixer, in the new concrete mixing cylinder, a new method was used to test the glass mixing cylinder in the field for one year by applying the detailed results formed by the iron-based wire arc coating on the mixing cylinder.Highly wear-resistant wire arc coating not only extends the life of the photosensitive drum, it is enabled to reduce the weight, relative to the drum by being able to use thinner gauge material AR-200 board. The results of the field test showed how new and different coating drum can be increased payload, and can double the retention time.Deal with problems on a number of concrete mixers and square uneven mixing spiral blade spiral blade discharge slowly, produced a new method is proposed based on the principle of mixing tube spiral blade on differentiation, we deduced the logarithmic spiral and helical square. Combined with the actual demand, a new and different drum helical mixing blade was designed.Compared with the traditional concrete mixer's spiral blades, the new spiral helix lead angle becomes small, within a certain range. Changes in the diameter range of pitch and the tapered portion are more reasonable, which have established a new mathematical model for mixing drum.
