Several mixing stages have been noted before about the batch plant. The dry mixing is characterized by constant power consumption and low power fluctuation. The liquid loading produces a sharp increase in both power consumption and power fluctuation. A few seconds after liquid loading mobile block machine, the mixture still reveals a dry appearance, although the formation of small granules can now be observed. These granules grow up as mixing progresses.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixer, concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc.
During this 1st mixing-stage for the concrete mixing equipment the power consumption and its fluctuation become stabilized but at higher levels than during the dry mixing. The 2nd mixing-stage is characterized by a second sharp rise in both power fluctuation and power consumption. The granules are wetted and conglomerate. Wet granules' coalescence is more visually discernible upon entering in the 3rd mixing-stage, in which the mixture appears to be already a paste with a “raspberry-like” shape. In the 3rd mixing-stage power consumption decreases yet large power fluctuations are still present. Once all volume has been transformed into a granular suspension, the free surface of the mixture becomes smoother. At this particular mixing time, power fluctuation decreases rapidly and significantly while power consumption continues to decrease. The planer surface of the concrete however displays lumps whose size decreases as mixing continues, which generates a creamy appearance at the end of mixing.
