The driving device is one of the important components of the asphalt mixing plant, so whether it can operate reliably must be highly valued to avoid adverse effects on the entire asphalt mixing plant. In order to ensure that the driving device in the asphalt mixing plant is indeed complete and reliable, the following maintenance measures are essential.
The first thing to pay attention to is the universal rotating part of the driving device of the asphalt mixing station. This part has always been a fault-prone part. In order to reduce the incidence of faults, grease should be added on time, the wear and tear should be checked frequently, and repaired and replaced in time. . Users should also prepare a cardan shaft assembly to avoid affecting the working process of the entire asphalt mixer.
It is also necessary to ensure the cleanliness of the hydraulic oil used in the asphalt mixing station. After all, the working environment of the equipment is relatively harsh, so sewage and sediment must be prevented from entering the hydraulic system. Hydraulic oil should also be replaced regularly according to the instructions in the user manual. Once water or sediment is found mixed in the hydraulic oil during inspection, the machine must be shut down immediately to clean the hydraulic system and replace the hydraulic oil.
Asphalt mixing plants require supporting cooling devices, which are also an important concern in the drive system. To ensure that its effectiveness can be fully exerted, on the one hand, the hydraulic oil radiator must be cleaned regularly to prevent the radiator from being blocked by cement; on the other hand, it is also necessary to check whether the electric fan of the radiator is operating normally to prevent the hydraulic oil temperature from exceeding the standard.
As long as the hydraulic oil of the driving device of the asphalt mixing plant is kept clean, there will generally be few faults. However, different manufacturers have different service lifes. Pay attention to its alkalinity and replace it in time.

    The actual operation steps of drying drum of asphalt mixing equipment: 1. Pay attention to routine inspection; 2. Proper operation steps; 3. Effective maintenance.
    Drying drum is a cylindrical device specially used for heating and drying stones in asphalt mixing equipment. Proper application and maintenance of drying drum can maximize the performance of drying drum, increase its service life and reduce application cost. Let’s take a look at the actual operation steps below.
    1. Pay attention to routine inspections
    The asphalt mixing equipment drying drum has been tested and inspected before leaving the factory, but it will be subjected to vibration and vibration during transportation to the construction site. A comprehensive inspection should be carried out before use: check whether all anchor bolts are tightened; whether all key pins are properly driven; whether all drive devices are adjusted according to the manufacturer’s instructions; whether all pipe connections are appropriate and whether the three-way joints are reliable; whether the entire equipment is fully lubricated; start the motor and check whether all parts can rotate steadily in the correct rotation direction; whether the pressure gauge can work normally and whether the valve is adjusted to the correct working pressure; whether the burner ignition mechanism is available and whether the gate valve is open.
    2. Correct operation steps
    After the equipment is started, it is recommended to control the machine manually at the beginning, and then switch to the automatic control mode after achieving the required production volume and pouring temperature. The stone should be dried and have a stable moisture content as much as possible so that the stone can maintain a stable final temperature when passing through the drying drum. If the stones delivered to the drying drum change frequently and the moisture content changes each time, the burner should be adjusted frequently to compensate for these changes.
    The stones directly from the crushed stone have a relatively constant moisture content, while the stones from the outdoor storage yard have a higher moisture content, and the moisture content of different piles varies greatly. Therefore, it is best for the stones to come from the same source.

    The materials used in asphalt mixtures contain a lot of dust. When the equipment is operating, if the dust enters the atmosphere, it will cause pollution. Therefore, dust removal equipment must be installed, and now bag dust removal is the main method. Safety is a common sense issue. There are well-established standard safety rules.
    Do not clean, oil or adjust any mechanical equipment that is not specifically explained during operation; turn off the power and lock it before inspection or repair activities to prepare for accidents. Because each situation has its own particularity. Therefore, be vigilant about safety damage issues, incorrect operation issues and other deficiencies. All of them may lead to accidents, personal injuries, reduced production efficiency, and more importantly, loss of life. Careful and early prevention is the best way to avoid accidents.
    Careful and correct maintenance can make the equipment work more efficiently and control it within a certain level of pollution; the maintenance of each component should be carried out according to its operating standards; maintenance plans and safe operation procedures should be formulated according to the inspection and repair conditions that must be carried out.
    Take out a work log to record all inspection and repair conditions, list the analysis of each inspection of each component and the description of the repair content or the date of the repair; the second step is to give the inspection cycle for each component, which should be determined according to the service life and wear condition of each component.
