What are the benefits of using complete sets of equipment in asphalt mixing plants?

In fact, don’t be misled by the name. The asphalt mixing plant we are talking about here does not necessarily refer to simple asphalt mixing, but may also refer to asphalt concrete mixing, so it is actually a mixing plant. At present, asphalt mixing plants generally use complete sets of equipment for mixing purposes. The benefits of using complete sets of equipment are as follows.
1. Higher efficiency
For the current industrial production, complete sets of equipment can help improve production efficiency and ensure production quality. This is why even in mixing plants, the equipment used is mainly complete sets of equipment.
2. Ensure quality
When mixing asphalt, a certain ratio will be set. For this type of asphalt liquid used in different occasions, its ratio control has strict requirements. Only by ensuring its mixing method and mixing time can the asphalt liquid be ensured to be used in the production site. One of the benefits of a mixing station is that the quality can be effectively controlled.
3. Ability to perform random inspections
After mixing at the mixing station, relevant quality inspection personnel can conduct random inspections to ensure that the mixed asphalt liquid meets the use requirements.
In short, asphalt mixing plants use complete sets of equipment, mainly to facilitate the asphalt to meet production needs in the later stage. Using a mixing plant, it can better control the mixing time and the order of feeding, so as to ensure that the mixed products meet different usage requirements. And after using the archived equipment, effective sampling can also be carried out, which can better ensure that the quality meets the construction.

    More Asphalt Processing

    Asphalt mixing stations, also known as asphalt concrete mixing stations, can produce asphalt mixtures, modified asphalt mixtures, and colored asphalt mixtures, which fully meet the needs of building highways, grade roads, municipal roads, airports, ports, etc. Changmeng Electric Power introduces the safety operating procedures of asphalt mixing plants below:
    1. During the operation of the mixing equipment, in addition to ensuring that the equipment is in good condition, it should also be equipped with a mineral moisture content detector and a finished material tester, and the relevant data should be frequently tested for the operator to adjust the operation in time to keep the equipment in good condition.
    2. In addition to affecting production capacity, the moisture content of mineral materials is also the main factor determining fuel consumption. Additional material sheds should be added.
    3. Before operation, all working parts and devices of the mixing equipment should be fully checked to see if they are intact and normal. If there are any problems, they must be properly handled before operation, and it is forbidden to operate with illness.
    4. The operation must be carried out strictly in accordance with the procedures and precautions specified in the instruction manual. After normal ignition, the dust collector should be monitored to ensure that the drying drum burns under negative pressure; after production starts, the hot material elevator and agitator should be monitored to see if they are working normally to coordinate the operation of other parts.

    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 asphalt mixing equipment mentioned here may also refer to an asphalt concrete mixing station. At present, asphalt mixing equipment generally uses a complete set of equipment for mixing. So what are the benefits of using a complete set of equipment?
    1. More effective.
    In today’s industrial production, a complete set of asphalt mixing equipment can help improve production efficiency and ensure product quality. This is why even in a mixing station, the equipment used is a complete set of equipment.
    2. Ensure quality.
    When mixing asphalt, a certain ratio is set. For this type of asphalt liquid used in different occasions, its ratio control has strict requirements. It is necessary to determine its mixing method and mixing time to ensure that the asphalt liquid is consistent with the production site. One of the advantages of a mixing station is that the quality can be effectively controlled.
    3. It can be sampled.
    After mixing at the mixing station, the quality inspector can sample and inspect to ensure that the mixed asphalt liquid meets the use requirements.
    In short, asphalt mixing equipment will use a complete set of equipment, mainly to facilitate the later asphalt to meet production needs. Through the mixing station, the mixing time and feeding sequence can be better controlled, so that the mixed product can meet different use requirements. And after using the archiving equipment, effective spot checks can be carried out, which can better ensure that the quality meets the construction requirements.

    With increasingly stringent environmental protection policies, asphalt mixing stations face severe challenges such as excessive dust and exhaust gas emissions. How to achieve standard production through efficient and environmentally friendly transformation while controlling costs? This article will reveal three core transformation plans to help mixing stations achieve a direct reduction of more than 80% in emissions, combining economy and compliance!
    1. Dust control: Upgrade pulse bag dust removal system
    Traditional dust removal equipment is difficult to cope with high humidity and high viscosity dust in asphalt stations, which can easily cause filter bags to compact. The transformation plan includes:
    Filter material upgrade: Use oil-proof and waterproof coated filter bags, which can withstand 240℃ high-temperature asphalt flue gas and extend the service life by 2 times.
    Intelligent cleaning: Equipped with a 0.5MPa high-pressure pulse backflush device, the cleaning frequency is automatically adjusted according to the pressure difference, and the dust capture efficiency exceeds 99%.
    Seal transformation: Install double-layer soft curtain seals on dust-raising points such as silos and conveyor belts to reduce unorganized emissions.
    Transformation effect: dust emission concentration dropped from 100mg/m3 to below 10mg/m3, which is better than the national standard.

    The drying drum of the asphalt mixing plant should pay attention to daily inspection, correct operation and reasonable maintenance, so as to extend its service life and reduce the cost of engineering use.
    1. Pay attention to daily inspection. Before the asphalt mixing plant officially works, the drying drum needs to be tested and inspected to see whether each pipeline is reliably connected, whether the lubrication of the whole machine is feasible, whether the motor can be started, whether the functions of each pressure valve are stable, whether the instrument is normal, etc.
    2. Correct operation of the mixing station. At the beginning of the asphalt mixing plant, manual operation can only switch to automatic control after reaching the specified production capacity and discharge temperature. The aggregate should be dry and have a standard mode so that it can maintain a constant temperature when flowing through the drying drum. When the entire aggregate is sent to dry, the moisture content will change. At this time, the burner should be used frequently to compensate for the change in moisture. During the rolling stone processing, the amount of water directly formed is basically unchanged, the amount of combustion accumulation increases, and the amount of water in the deposited accumulation material may change.
    3. Reasonable maintenance of the asphalt mixing plant. Aggregates should be deactivated when the asphalt mixing plant is not in operation. After work every day, the equipment should be operated to discharge the aggregate into the dryer. When the material in the hopper leaves the combustion chamber, the combustion chamber should be closed and allowed to idle for about 30 minutes to cool down, so as to reduce its impact or make the machine run in a straight line. Install the drying cylinder fixing ring on all rollers synchronously.
