According to the design life calculation of asphalt premix pavement in our country, about 11% of the pavement in our country needs to undergo large-scale maintenance every year. Regardless of the type of maintenance, a lot of waste asphalt mixture will be generated. If such mixture is not fully utilized, it will cause great losses and serious pollution to the environment. Therefore, our country advocates using asphalt milling, planing, crushing and screening equipment to increase construction workload. Similarly, these waste asphalt mixtures can be reused through equipment, with a utilization rate of over 90%.
However, as a user, when using equipment for reusing waste asphalt mixtures, due to the harsh environment during the entire crushing and screening process, the daily workload is relatively large, which can easily affect the aging of equipment components, leading to various small problems, reducing equipment efficiency and service life. Therefore, in order to maintain normal operation during use, maintenance and upkeep should be done throughout the entire process.
When the equipment for reusing waste asphalt mixture is undergoing maintenance and upkeep, it belongs to the break in period 1-2 months before use, which is often prone to serious damage to some components. Therefore, the workload during the break in period should not be too large. For example, if the daily work volume can reach 200 tons, the workload should be reduced by 10% -20% during the break in period to protect the equipment.
Another thing is that after three months of use, every part of the equipment's bearings must be inspected. After inspection, those that need to be replaced should be replaced in a timely manner, and those that do not need to be replaced should be filled with lubricating grease to ensure that the bearings operate normally without a lack of lubricating grease. In addition, regular inspections should also be carried out for other links, especially for screws that are loose. They should be checked and tightened, and the surface should be regularly wiped to keep it clean and tidy. Only in this way can the equipment operate normally throughout the entire operation process and have a longer lifespan.
The equipment for reusing waste asphalt mixture is a type of equipment with high technical content, which is a crushing and screening equipment for waste asphalt mixture. It is simple and convenient to operate, and has high work efficiency. It is an indispensable equipment for the recycling and utilization of waste asphalt pre mixed materials. As long as the equipment is regularly maintained throughout the use process, it can ensure normal operation and high work efficiency.
