Common Problems and Solutions of Asphalt Mixing Plant
Asphalt mixing plant plays a very important role in the construction of highways in China, and the quality of the equipment directly affects the progress and quality of the project. This equipment is equipment for producing asphalt concrete with many advantages, but there are still some problems in use. This article will briefly describe the common problems and corresponding solutions of the asphalt mixing plant.
One of the most common failures 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 shutdown of the variable speed belt. The main reason for this phenomenon is that there is too little raw material in the cold hopper, which makes the impact of the loader on the belt too large when loading, so the cold material feeding device will stop working due to overload. The solution to this problem is to ensure that the quantity of raw materials stored in the feeding device is sufficient.
The failure of the concrete mixer in the asphalt mixing plant is also one of the common problems. Generally speaking, the abnormal noise of the machine is caused by the overload work. The solution to this problem is to check regularly to confirm whether there is a problem. If there is a problem, it is necessary to replace the fixed bearing.
During the operation of the asphalt mixing plant, problems with the screen mesh are also common. For the screen mesh, due to the excessive proportion of asphalt aggregate in the mixture during the operation, the pavement after paving and rolling will appear Youbing (Deep-fried round and flat dough cake). The main reason for this problem is that the screen mesh has large holes, so it is necessary to check whether the screen mesh device is reasonable at this time.
