Common problems and solutions of asphalt mixing stations
The cold feed unit is faulty
In the general operation, the device will appear variable speed belt machine shutdown phenomenon, the cause of this phenomenon, 80% from the cold hopper memory of the raw material is too small, and then lead to the loader in the feeding of the belt machine device has an excessive impact, directly causing the cold feed device to stop working due to overload, the solution to the problem is to ensure that the number of memory raw materials in the feed device is sufficient; Moreover, the control inverter of the variable speed belt machine's own control box fails, and it should be repaired and replaced in time; When the belt appears, such as slippage, deviation and other issues, it is necessary to adjust the update tension in time, and finally during construction, it is unintentional to encounter an emergency pulling line, and the builder can work after restoration.
Asphalt concrete mixer malfunction
Regular inspection of the fixed bearings of the repair mixer and the fixing support of the bearing drive motor, generally due to the abnormal sound of the machine after overloading, the solution measures are to replace the fixed bearing. If the phenomenon of uneven and delicate mixing material occurs during construction, it is generally worn or shed by the device robot arm. Finally, if the stirrer discharge temperature sensor is not checked and cleaned in time, the temperature display will be abnormal.
Problems with the screen
For the screen, the proportion of oil and stone in the mixture will be too large during construction, and the specific phenomenon of oil cake will appear on the road surface after paving and rolling, and the reason for this problem is that the screen has a large hole, resulting in the aggregate of the previous gear directly in the silo of the next file. Therefore, regular and timely sampling and screening data for detection and comparison, after the occurrence of problems, you can give priority to the inspection device screen.
The temperature is uneven when the asphalt concrete is discharged
In practice, if the attention to temperature is not enough, there will be "paste" without any use value, and the general reason is that the temperature is too high and directly leads to the asphalt being burned; Another phenomenon is the occurrence of "white material", which is caused by the instability and uneven adhesion of asphalt and sand and gravel, and the temperature is too low. Its loss is large, so there is a need for a higher level of grasp and requirements for the management and operation of asphalt concrete production sites.
