There is a stipulation in the usage standards of asphalt mixing equipment that the blades of the mixing equipment cannot be started with the blades buried in the solid phase precipitation layer. Although this stipulation has been followed, do you know why it is done?

Of course there is a reason. If the blades of the asphalt mixing equipment are buried in the solid phase sedimentation layer and started, its starting power will be very large, which may easily cause accidents to the motor and blades. On the other hand, it would be uneconomical to select the motor and design the blades based on the starting power at this time.
The correct way is to set the blade position of the asphalt mixing equipment higher than the solid phase sedimentation layer, but it is also necessary to consider that the sedimentation layer particles under the blades can also be gradually suspended before starting the machine.
