Common problems and solutions of asphalt mixing plants
Asphalt mixing plants play a very important role in the construction of highways and other areas in China, and the quality of the equipment directly affects the progress and quality of the project. This equipment is a device with numerous advantages for producing asphalt concrete, but there are still some fault problems encountered during use. This article will briefly describe the common problems and corresponding solutions of asphalt mixing plants.
One of the common faults in asphalt mixing plants is the failure of the cold material feeding device. Generally speaking, the failure of the cold material feeding device refers to the problem of variable speed belt shutdown. The main reason for this phenomenon is that there is too little raw material stored in the cold material hopper, which causes the loader to have too much impact on the belt during loading, and therefore the cold material feeding device will stop working due to overload. The solution to this problem is to ensure that the quantity of stored raw materials in the feeding device is sufficient.
The failure of the concrete mixer in the asphalt mixing plant is also a common problem. Generally speaking, it is caused by overloaded work that causes abnormal noise. The solution to this problem is to regularly inspect and confirm whether there is a problem, and if so, 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.
