Make a scientific maintenance plan

After the shutdown of the asphalt mixing plant in winter，A scientific and effective maintenance plan should be formulated.，Strictly follow the maintenance manual。

For some bearings that are greased regularly，Be sure to fill up with grease or cover the oil filler.，To prevent snow from seeping into the bearing.，Cause rusting。

For some important electrical components，Uch as an infrared temperature sensor,，To prevent lens fogging，It is better to disassemble, retrieve and preserve.。

Prevent snow, water, moisture, rust and rat damage

When the asphalt mixing plant is shut down in winter，Burner and motor shall be covered with tarpaulin，Do a good job of snow water、Damp-proof work。Cold and hot silos and dust silos shall be emptied，Prevent caking when entering the tide。Clean the dust remover.，Leak-proof and waterproof work shall be done after installation.，Prevent the cloth bag from getting damp, etc.。

Belt needs to be tensioned during production，After winter, the belts need to be adjusted to be loose.，Prevent the belt from cracking or deforming due to thermal expansion and contraction。

The harm of rodents to industry is mainly in the field of electricity.，In the winter，Many asphalt mixing plants are shut down for a long time.，The station may become a winter shelter for rats.，Cable Tray、The position of the control room shall be well protected against rats.，If necessary, take measures to protect the equipment, such as putting the rat killer.。

Maintenance of Asphalt Mixing Plant during Winter Downtime，A scientific inspection and maintenance plan should be made.，If problems are found, they should be solved in time.，Ensure that the equipment is in good working condition at all times，Make adequate preparations for production after commencement。
