The delivery pump and other motors and reducers of the modified bitumen equipment need to be maintained in accordance with the provisions of the manual. The dust in the control cabinet needs to be removed once every six months. The dust can be removed with a dust blower to prevent dust from entering the machine and damaging the machine parts. The colloid mill needs to add butter once for every 100 tons of emulsion bitumen produced. After using the agitator, it is necessary to check the oil mark frequently. If the modified emulsified asphalt equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving part also needs to be filled with lubricating oil.
