Asphalt batching plants are one of the indispensable equipment in the construction of roads, highways, bridges, and other infrastructure projects. To ensure the smooth operation of the asphalt mixing plant, a trial run of charging the raw materials is a crucial part. At this golden moment, we will unveil the whole process of asphalt batching plants about the loading and running test, presenting every key step for you. Finally, we hope we can help you to better understand and master this important process.
Why Is It Important To Conduct Trial Run On Asphalt Batching Plants?
An asphalt mixing plant is used to produce asphalt concrete equipment, and a trial run of loading raw materials is an important procedure before officially put into production. The main purpose of the trial run is to ensure that the asphalt mixer plant can work normally, stably, and efficiently before the official production operation, so as to guarantee the quality and safety of the production process. The following is the importance of loading test run.
Verification Of Equipment Performance
Charging trial run is the process of verifying the performance of asphalt batching plants near me. Through this stage, you can check and confirm whether the function of each equipment component is normal, to ensure that the actual production will not be due to equipment failure resulting in production interruption or quality problems.
Process Parameter Debugging
During the trial run, the process parameters of the asphalt batching plants for sale can be debugged. This includes adjusting the mixing ratio, temperature control, mixing time, and other parameters to ensure that the quality of asphalt concrete in the production process meets the requirements.
System Integration Test
Asphalt mixer plant usually contains several systems and components, such as a silo system, mixing system, conveying system, and so on. System integration testing after loading commissioning ensures systems work together smoothly.
Personnel Training
Trial run with loading raw materials is an opportunity to train operators. In this phase, operators learn equipment procedures, emergency response, and maintenance for productivity and safety.
Safety Check
Besides, trial run is an important stage in the safety check. By simulating the production process, potential safety hazards can be identified and resolved in a timely manner to ensure that there are no safety issues caused by equipment failure or operational errors during the production process.
Quality Assurance
The loading trial run ensures the asphalt concrete meets quality standards at the plant mix asphalt. During the trial run phase, we can test and adjust various parameters to ensure the stability and consistency of the final product.
After understanding the necessity of conducting trial runs in the asphalt mixing plant, including the trial run of small asphalt plant,stationary asphalt mixing plant, then let’s explore the process of loading a trial run in asphalt batching plants!
Preparation Of Asphalt Batching Plants Before Trial Run
Preparation is key for a smooth start to an asphalt mixing plant’s loading trial run. We must ensure that the asphalt mix plant runs smoothly. This stage involves a number of checks and preparations for mechanical, electrical, and electronic controls.
- Equipment inspection and lubrication: The equipment installer of the asphalt batch mix plant is responsible for comprehensively inspecting the equipment, including machinery, electrical appliances, electronic control, etc., adding lubricating oil, cleaning up the debris on the plant site to ensure that everything is normal.
- Raw material preparation: Preparing and loading the aggregate, stone powder, and asphalt into tanks (or silos) to ensure that the continuous mixing process is fluent.
- Lubricating oil preheating: Ignite the heat-conducting oil furnace 40 minutes to 1 hour in advance, turn on the heat-conducting oil pump, and let the circulating hot oil preheat the asphalt pipeline, asphalt pump, asphalt valve sufficiently to ensure efficient working condition.
- Transportation vehicles in place: Material transport vehicles must be ready beforehand for a smooth trial run at asphalt batching plants.
Through this part of the narrative, we have grasped the importance of the preparatory work, and then we will delve into the specific operation of the mixing process.
Mixing Operations During The Trial Run Of Asphalt Batching Plants: Organized And Coordinated
The mixing operation during the commissioning phase is a critical step to ensure coordination and stability between the equipment. The following is an organized operation procedure to ensure the smooth running of the trial operation.
- Heat transfer oil pump: Start more than 40 minutes in advance. Then you can ensure that the heat transfer oil system is preheated.
- Asphalt Circulation Pump: Start the circulation of asphalt and allow it to warm up in the pipeline.
- Dust collector induced draft fan: Ensure clean air flows into the system.
- Air Compressor: Provides the required air pressure to the system.
- Mixing Pot Discharge Door: Opens the mixing pot discharge door in preparation for the start of mixing.
Turn on the mixing pan, vibrating screen, hot elevator, drying cylinder, drying cylinder burner, stone powder feeding screw, inclined belt conveyor, cold material rotating screen, flat belt conveyor, and integrated bucket dispenser in turn. Ensure that there is a proper time interval (10~15 seconds) between the equipment during the turn-on process to minimize voltage fluctuation and improve the stability of the system. More videos about asphalt batching plants are on YouTube.
By starting up the equipment in an orderly manner, we have taken the first step of the running test of asphalt mixing plant. Next, we will delve into the key things to pay attention to during the mixing process.
Precautions During The Mixing Process Of Asphalt Batching Plants
During the mixing process at an asphalt batch mixing plant, there are some key operations that require special attention to ensure mixing quality and normal operation of asphalt batching plants. The following are the precautions for these key operations.
- Aggregate Control: You should keep the aggregate in the cold hopper full to ensure uniformity of batching. For uneven grading, you can solve it by adjusting the parameters of the grading machine and lowering the speed control motor speed of the corresponding specification bin.
- Asphalt Temperature Control: Add asphalt at regular intervals and ensure the temperature of asphalt in the high-temperature asphalt tank and the temperature of discharged material are kept between 130~160°C to meet the users’ demand.
- Transmission System Check: Monitor transmission systems, note temperature fluctuations, observe smooth belt and chain operation for any unusual noise, ensuring equipment runs normally.
- Record And Monitor: Fill in the “Asphalt Mixing Plant Discharge Operation Record” in time during the discharge operation, so as to monitor the key data in the mixing process.
The above precautions help to ensure the quality of the mixing process and the normal operation of the asphalt plant. By carrying out these key operations carefully, you can improve the productivity and product quality of asphalt mixing plants. Finally, you can make them meet the requirements of the project. Next, we will learn how to park the asphalt batch plant properly.
Shutting Down Asphalt Batching Plants: Completing The Running Test In An Orderly Manner
The last important step of the trial run is the stopping operation. This phase must be done in a specific order for safe equipment shutdown and effective cleaning afterward.
Normal stopping principle
The principle of normal stopping is to use up the asphalt in the asphalt weighing tank, mixing and unloading the machine stock. Before stopping the machine, carry out a “Pan-rinsing” operation. Then you can remove the residual asphalt in the mixing tank to ensure the cleanliness of the equipment.
Shutdown Sequence of Asphalt Batching Plants
The shutdown sequence includes stopping the asphalt circulating pump, reversing for 5 minutes (pumping the asphalt in the pipeline back to the asphalt tank), and stopping other equipment, such as the coal pulverizer screw conveyor, grading machine, vibrating screen, and hot elevator, etc. The interval between each piece of equipment is 10 minutes. The stopping interval between each piece of equipment is 10~15 seconds to ensure the stability of stopping.
Through the above steps, we have completed the trial run of asphalt batching plants. Each step is to guarantee the normal operation of the equipment and mixing quality.
