The Daily Operation of Hot Mix Asphalt Plant

1. The Daily Operation of Hot Mix Asphalt Plant Abstract: With the increase of infrastructure construction in many countries, hot mix asphalt plant is strongly demanded. How to choose a proper location and what should you notice in daily operation? Welcome to read this page. Where to Build Hot Mix Asphalt Plant With the rapid development of infrastructure in many countries, the need for batch type hot mix plant is stronger. Many customers are planing to invest in them. In this process, it is very important to choose a proper location. Generally speaking, if you want to choose a suitable construction site for stationary asphalt plants, there are four main aspects: Firstly, the manager needs to know clearly the distance between the asphalt mix pant and the construction sites for the transportation distance of asphalt as a raw material directly affects the quality of asphalt. The plant builder needs to confirm the distribution of the asphalt according to the construction drawings, so that it can be positioned to the approximate center position of the asphalt mixing plant.

2. Secondly, the asphalt plant builder needs to master the basic elements of the asphalt mixing station, such as the water, electricity, and floor space required during the operation of the asphalt batch plant. Thirdly, pay attention to the surrounding environment of the construction site. Since there is some pollution like dust and noise generated during processing, it is better to be far away from schools, residents’ living areas and farmland. As a asphalt batch mix plant manufacturer, Haomei Machniery has the most Eco-friendly dust-collecting system, reducing the pollution to the minimum. The last but not least, the site selected for the construction of asphalt plant can be divided into soft foundation and solid earth. Since batch type asphalt mix plant has strong vibration power on the ground, extra reinforcement measures need to be done for soft foundation. How to Choose Fuel Oil for Batch Type Asphalt Plant For hot mixer asphalt plant, the fuel oil should be of moderate viscosity, good combustion performance, high heating value, good atomization performance, complete combustion, little carbon deposits and ash, small corrosion to the burner parts. Fuel oil is divided into light oil and heavy oil according to different viscosity grades. Light oil does not need to be heated to obtain a good atomizing effect. Heavy oil is generally prepared from cracked heavy oil, vacuum heavy oil, atmospheric heavy oil or wax oil in different proportions.

3. The cracked heavy oil has larger viscosity and relative density than the vacuum heavy oil and atmospheric heavy oi , and contains larger solid impurities. They are easy to precipitate and block pipelines and fuel preheaters, and are not easy to burn. So the heavy oil with less proportion of the cracked heavy oil is better. Before heavy oil or residue oil is used, the oil must be heated to ensure that the viscosity of the oil is within the allowable range of the hot asphalt plant burner. The operator can use a viscometer to measure the results and find the best fuel heating temperature. After using heavy oil or residual oil for a period of time, check and adjust the burner. A combustion gas analyzer can be used to determine whether the fuel is fully burned. At the same time, check the drying drum and dust collector to see if there is oil mist or smell to avoid fire and oil pollution. The oil deposits on the atomizer will increase with the deterioration of the oil, so it should be cleaned regularly. As an asphalt mixing plant manufacturer, Haomei like to share with you more on asphalt plant. The Safe Operational Tips of Asphalt Hot Mix Plant 1. Various mechanical and electrical equipment of the asphalt batch plant must be carefully checked by mechanics, electricians, and computer operators before operation, and the plant can starts working after being confirmed that they are normal and intact. 2. After the hot mix plant for sale is put into operation, all departments and workers must monitor the operation of each part at any time and must not leave the post without

4. authorization. 3. It is strictly forbidden for personnel to approach various operating systems during operation. 4. If any abnormal situation is found during operation, the team manager should be reported and the fault should be eliminated in time. Before stopping, the feeding should be stopped first, and the whole machine only can be stopped after the material of drying drum and other parts has been discharged. 5. While the mixer is running, do not use tools to reach into the drum for digging or cleaning. When cleaning is required, it must be stopped. 6. When the hopper is raised, no one is allowed to work or pass under the hopper. When inspecting the hopper, the safety chain should be hung up. As a hot mix asphalt plant manufacturer, Haomei Machinery pays attention to every detail. The stairs has been set in the parts of the mixing plant where the machinery and equipment need to be checked frequently.
