How much do you know about the spiral blades of the mixing drum of the automatic mixer truck? Do you know what role it plays in the whole mixer? In order to let you better understand this part, let's first know the design principle of the spiral blade of the mixing cylinder of the automatic mixer truck.
The mixing blade is generally designed to rotate clockwise for feeding and mixing, and counterclockwise for discharging. The rotation speed of the mixing drum is fast during feeding to save working time. The rotation speed of the mixing drum is slow during mixing to reduce water evaporation and segregation.
However, the mixing drum must be operated at a constant speed during transportation to prevent concrete from solidification and deterioration. During the rotation of the cylinder, the concrete is continuously pushed to the front of the mixing cylinder by the blade, and the concrete that reaches the front end will be pushed back by the end wall of the mixing cylinder, so that the concrete will roll back and forth;
The continuous rotation of the two blades drives the continuous rotation of the concrete, and the concrete at the same position changes continuously through this movement, thus playing the role of mixing;
In addition, the change of blade shape curve can make the concrete form a small circular movement between its root and the cylinder wall, which also plays a role in mixing concrete.
When the concrete is transported to the work place, the mixing drum will rotate counterclockwise, and the rotation direction of the blade is also opposite, and the concrete will be guided by the blade to the mixing drum mouth until it is discharged from the drum mouth.
This is the relevant content of the design principle of the spiral blade of the mixing drum of the automatic mixer. If you have any questions about this, you can come to our website at any time http://www.hzxdsc.com Leave a message for consultation!
