Vulnerable parts
- Agitator blades
Agitator blades are one of the most easily worn components in hot mixing plants. Due to long-term contact with high-temperature asphalt mixtures, the blades are prone to deformation and wear.
- Vibration screen
Vibration screen is used to screen asphalt mixture according to particle size. Due to its continuous vibration, the screen mesh and supporting components are prone to wear and loosening.
- Conveyor belt
The conveyor belt is used to transport asphalt mixture from the hot mix station to the storage bin or construction site. Due to its long-term contact with high-temperature and slippery mixtures, the conveyor belt is prone to wear and deviation.
- Reducer and motor
The reducer and motor are the power transmission components of the hot mixing station, and due to their long-term high load operation, they are prone to overload and heating.
- Pipes and valves
Pipes and valves are used for the feeding, discharging, and circulation of hot asphalt and cold aggregates in hot mixing plants. Due to the harsh working environment, they are prone to blockage and leakage.
Maintenance methods
- Agitator blades
Regularly check the wear of the agitator blades. If severe wear or deformation is found, they should be replaced in a timely manner. At the same time, keep the mixer clean to prevent debris and hard objects from entering the mixer.
- Vibration screen
Regularly check the wear of the screen mesh and supporting components of the vibration screen. If severe wear or looseness is found, it should be replaced or tightened in a timely manner. At the same time, keep the vibrating screen clean to avoid debris blocking the screen mesh.
- Conveyor belt
Regularly check the wear and deviation of the conveyor belt. If severe wear or deviation is found, it should be replaced or adjusted in a timely manner. Meanwhile, keep the conveyor belt clean to avoid damage from debris and hard objects.
- Reducer and motor
Regularly check the operation status of the reducer and motor. If any abnormal sound or severe heat is found, stop the machine for inspection and repair in a timely manner. Meanwhile, keep the reducer and motor clean to prevent debris and hard objects from entering the interior.
- Pipes and valves
Regularly check the sealing and smoothness of pipes and valves. If leakage or blockage is found, it should be dealt with or replaced in a timely manner. Meanwhile, keep the pipes and valves clean to prevent debris and hard objects from entering the pipes or valves.
Summary
The vulnerable parts of the asphalt hot mix plant mainly include mixer blades, vibrating screens, conveyor belts, reducers and motors, pipelines and valves, etc. To ensure the stability and production efficiency of the equipment, we need to regularly inspect and maintain these vulnerable parts, and replace severely worn parts in a timely manner. Meanwhile, selecting high-quality components and materials is also an important measure to extend the service life of the equipment. By using the correct maintenance methods, the wear of vulnerable parts can be effectively reduced and the service life of equipment can be improved, thereby reducing production costs and improving production efficiency.
