One of the more common faults of the asphalt mixing plant is the failure of the cold material feeding device. Generally speaking, the failure of the cold material feeding device refers to the problem of the variable speed belt stopping. The main reason for this phenomenon is that there are too few raw materials in the cold material hopper, which makes the loader have too much impact on the belt when feeding, so the cold material feeding device will stop working due to overload. The solution to this problem is to ensure that the amount of raw materials in the memory in the feeding device is sufficient.

The failure of the concrete mixer of the asphalt mixing plant is also one of the common problems. Generally speaking, it is due to the abnormal noise of the machine caused by overload. The solution to this problem is to check regularly to confirm whether there is a problem. If there is, it is necessary to replace the fixed bearing.
It is also common for the screen to have problems during the operation of the asphalt mixing plant. For the screen, during the operation, due to the excessive proportion of oilstone in the mixture, the road surface after paving and rolling will appear oil cake. The main reason for this problem is that the holes of the screen are large, so at this time, you should first check whether the device of the screen is reasonable.
