Winter maintenance of asphalt mixing plant is an important part to ensure the normal operation of mixing equipment, reduce the failure rate and extend the service life. As the asphalt mixing plant has been shut down for a long time after a long winter, various fluids, lubrication protection, and key parts may be changed. If the equipment is put into work without timely detailed inspection, problems such as the poor operation of the equipment are bound to occur. Subsequently, the service life of the equipment will be shortened and the progress of the project will be affected.
The cold climatic conditions will make the use of asphalt mixing plant face serious challenges. In order to make the mixing plant work smoothly under harsh climate conditions, the winter maintenance of asphalt mixing plant is crucial. It is necessary to ensure smooth production at the beginning of the next spring. Users and service engineers need to master some essential knowledge of cold weather maintenance of products.
Here are 7 tips for winter maintenance of asphalt mixing plant. See if you did this last year when it came to winter.
Winter maintenance of asphalt mixing plant about the bearings
The bearings on the equipment that must be greased regularly need to be full of grease or covered with a good oiling port. It can prevent rain, snow, and water from seeping into the bearings and causing rust and corrosion.
Winter maintenance of asphalt mixing plant about the motors and burners
All motors and burners should be covered with tarpaulin to prevent snow and moisture.
Winter maintenance of asphalt mixing plant against the rats
In winter, the mixing plant may become a winter shelter for rats. Cable troughs, control room locations, etc. should be well protected against rats and put sticky boards or rodenticides if necessary.
Winter maintenance of asphalt mixing plant about the belts
Belts need to be tightened during production. After winter, each belt needs to be adjusted to be loose to prevent the belt from cracking or deformation due to thermal expansion and contraction.
Winter maintenance of asphalt mixing plant about the silo
The cold silo, hot silo, and dust silo should be emptied to prevent caking.
Winter maintenance of asphalt mixing plant about the dust collector
The dust collector should be cleaned well. Do a good job of leakage prevention and waterproofing after installation to prevent the cloth bag from getting wet, etc.
Winter maintenance of asphalt mixing plant about the lubricant
If it is a municipal use plant, production is still needed in early winter. The lubricant of each reducer should be changed to the corresponding winter special oil.
Proper maintenance work and standardized operation can not only reduce equipment failure but also reduce unnecessary losses, which can greatly extend the service life of the equipment and reduce the cost of use. Large equipment such as asphalt mixing plant is afraid of failure and affect the production supply. To reduce equipment failure and protect the quality of asphalt concrete, these are inseparable from the maintenance work. Especially the annual maintenance before the winter and equipment maintenance before the start of work, are necessary to ensure that the equipment is always in good condition operation.
