1. Mobile and StationaryAsphalt Plant Abstract: What is the developing trend of hot asphalt plant in China? To meet the future need, both Haomei mobile and stationary asphalt plant has made many improvements in design. What’s the profit of investing asphalt batch plant? Welcome to read this page. The Developing Trend of Hot Asphalt Plant in China The technical level of domestic hot asphalt plant has been greatly improved in recent years, especially the reliability and durability. What are the developing trend of asphalt mixing plant in China? Lets have a look together. 1. Development of large asphalt mixing plant. The large-scale asphalt premix plant refers to the type LB 4000-5000. The technical content, manufacturing difficulty, industrial control method, and energy-saving and environmental protection requirements of large models are much higher than the small asphalt mixing plant. The technical problems that need to be solved with the

2. increase of the model will be more complex such as vibrating screen and dust removal system. 2. Energy saving, emission reduction, and environmental protection. The control of noise pollution, dust emission and harmful gas (asphalt smoke) emission is becoming stricter and stricter, which puts forward higher requirements for the technological development of asphalt batching plant. 3. Waste asphalt mixture recycling equipment. The waste asphalt is remixed with regenerant, new asphalt, new aggregate, etc. in a certain proportion after recycling, heating, crushing, and screening. The reuse of waste asphalt mixture will be widely popularized, and even gradually replace conventional products. 4. Automatic and intelligent control technology. With the increasing requirements of users for the automatic and intelligent control, the control system of mixing equipment will apply a large number of ergonomics design and mechatronics technology to further improve asphalt mixing weighing accurancy and the automatic level. The furture control system of asphalt premix plant needs to dynamically monitor all motor reducers, discharge gates, gas and oil pipeline valves, and provide real-time feedback on the operating status of components. It has self-diagnosis, self-repair, automatic fault detection, and real-time alarm functions. The final goal is to realize automatic production of the asphalt mixing plant. 5. Independent R&D and manufacturing of supporting parts, especially core parts. Core supporting parts are the foundation, support and restriction bottleneck for the development of the construction machinery industry. When the development of engineering machinery reaches a certain stage, the industry's high-tech research will mainly focus on core components such as engines, burners, control systems.

3. How Much Can Asphalt Batch Plant Make for You How much can an asphalt batch plant make a year? It is a question many customers who want to invest in an asphalt hot mix plant care about. In fact, asphalt production is of very high rate of return. Let’t have a look together. In China, according to he general price on the market, 1 ton of asphalt is about 3,500 RMB. One ton of asphalt can be used to produce 20 tons of asphalt concrete, of which about 18 tons of gravel (6.7m³), and about 2 tons (0.8m³) of sand and powder. The unit price of gravel is 60 RMB/m3and the unit price of sand and powder is 35 RMB/ m3. The cost of 20 tons of asphalt concrete material is 3500+6.7×60+0.8×35=3930 RMB, that is, the cost per ton of asphalt concrete material is 3930÷20=196.5 RMB. According to expert research, it is found that more than 75% of the total cost is related to materials (aggregate and asphalt). The fuel consumed when drying aggregates and heating asphalt comes next, accounting for almost 12% of the cost. The cost of equipment maintenance, transportation and installation, site construction, electricity, wheel loaders for unloading, and labor costs add up to less than 10% of the total cost. The investment in the batch type hot mix plant itself is less than 2%.

4. According to the cost ratio, the cost per ton of asphalt concrete is: 196.5×100/75=262 RMB. The price of asphalt concrete varies from place to place, but the average price is about 370 RMB/ton. so we can get the profit per ton of asphalt concrete is 108 RMB. Take LB4000 batch type hot mix plant for example. it can produce 300 tons of asphalt per hour and 2400 tons per day accordin to the 8 working hours. The total daily profit is 259,200 RMB. If the actual production in a year is 4 months, then the profit is 31,104,000 RMB. Different models have different output, and profit is also affected by asphalt concrete prices. Yet the domestic and international highway construction is relatively hot, and the profit of asphalt mixing plant is relatively high. It is a good choice to invest in asphalt mixing plant. The Design of Small Portable Asphalt Plant In line with their functions, Haomei small portable asphalt plant also stresses the detail design, which can not only improve the beauty, but also make it easier to operate. Lets have a look together. Semantic design of spare parts The product form reflects certain index and tells the operator how to use it. The design of asphalt mixing plant should rely on the semantic features of the product to guide the operation. For example: the shape of the door handle is used to indicate the correct direction of rotation of the door. Man-machine design The man-machine design is helpful for improving work efficiency, reducing training costs, increasing human resource utilization, reducing accidents and human errors, and increasing production efficiencyand user satisfaction. One of the man-machine

5. designs is the ladders and pedals. Its design not only meets ergonomic standards in terms of size, but also provides users with a safe and reliable psychological experience through materials, structure, non-slip and tactile sense. In actual use, the width, depth and steps of the pedal must conform to the human body size. The non-slip patterns can ensure the safety of operators in various working environments. Haomei Machinery, hot mix asphalt plant manufacturer, dopts advanced ergonomics to build safety fences or nets for key parts and high-altitude operations. The operating room and UI design The humanized operating space can indeed bring convenience to the operator's work and rest, and can bring a sense of intimacy to the operator, and enhance the emotional connection between the operator and the product and the company. The console, as the core component of the control room, satisfies human-computer interaction, with reasonable button positions, excellent materials and excellent touch. The design of the operation panel mainly includes instrument display design (current, voltage, temperature, etc.), signal display design (over-temperature warning light, material shortage warning light, overload warning light), fluorescent screen display design (display screen angle, ratio, brightness, etc.),etc. Haomei Machinery attaches great importance to the added value of industrial design and adopts green design based on ecological protection and protection of human beings, combined with ecological theory, providing operators with the best operation experience.

6. The ECO-friendly Design of Stationary Asphalt Plant A really ECO-friendly stationary asphalt plant involves many parts such as cold aggregate supply system, asphalt supply system, mixing system,etc. Let’s have a look of the environmental protection design of each part. Cold aggregate supply system 1. The closed type replacing the open type  The upward opening is closed, and the downward tilting type is subtly changed to the side window feeding type.  A dust removal pipe is installed above each hopper to form a negative pressure environment, and the dust is sucked into the bag filter through the pipe.  The special "curtain" has obvious dust blocking effect, greatly reducing dust spillage 2. The belt conveyor is no longer "naked", and there is no dust in the conveying process.  The belt conveyor is covered as a whole to completely eliminate the environmental pollution caused by dust during the conveying process.  The middle filter is encapsulated as a whole, and a dust removal pipe is installed above to

7. form a negative pressure environment, and the dust is sucked into the bag filter through the pipe. Asphalt supply system The use of active carbon  In order to filter the asphalt smoke, the exhaust port of the asphalt tank is equipped with high efficiency activated carbon.  Asphalt tanks and pipelines are provided with ultra-thick insulation layer to reduce heat loss. The asphalt mixing system 1. The mixing plant is fully enclosed to isolate dust and noise.  It is fully enclosed, eliminating the powder leakage.  The stationary asphalt mixing plant effectively isolate the sound emitted by the equipment and reduce noise pollution.  The wear-resistant noise reduction devices are installed at the entrance and exit of the hoist to reduce noise pollution.  The vibrating screen is tightly sealed as a whole, with intelligent air induction and pressure relief, realizing energy saving and environmental protection. 2. The loading room is fully closed.  A pipe is installed above the charging room to form a negative pressure environment. The asphalt smoke generated during the discharge process is transported to the drying drum to be heated and decomposed through this pipe to eliminate environmental pollution.  The closed loading room is equipped with a dust removal pipe, and the dust enters the bag filter through the pipe.  Automatic lift doors are installed at the exit of the lane, which is environmentally friendly and tidy. Types Of Asphalt Plants The asphalt mixing plant plays an important role in the construction of roads, airports and other facilities. It can provide the necessary asphalt concrete. For meeting the requirements of different construction projects, there are different types of asphalt plant.

At the same time, it cancels the finished material trolley lifting mechanism, reducing the failure rate of the equipment.  Place the cloth bag dust removal above the drying drum to reduce heat loss and save fuel and space  The linear vibrating screen driven by imported vibrating motor improves the screening efficiency and reduces the equipment failure rate.  The aggregate elevator adopts double-row plate chain for lifting, which increases the service life of the elevator and improves the stability of operation  Special mixing blade design and extraordinary power-driven mixing tank make mixing easier, more efficient and reliable.  Modular design makes the transportation and installation faster and more convenient. How to Invest in Mobile Asphalt Plant When we plan to invest a mobile asphalt plant, what should we consider? It is a quite complex issue. Let’s have a look together.

10. Firstly, what needs to be considered is the the precautions for the application of asphalt mixing plant technology. Under the normal situation, the main technical issues include:  The reliability and applicability of the technology used in the asphalt mixing plant project in practical applications. We need to consider if there is uncertainty.  We also should consider what risks these technologies bring in the actual production. We should adhere to this principle: the selected technology and asphalt premix plant is mature and has good feasibility. Secondly, there are some instructions for the asphalt mixing plant. Although the development in this area has been in a rising period in recent years, it is obvious that there is also a large profit margin. However, we should still be cautious when investing, and we need to make corresponding preparations before investing. 1. Have a good preliminary research and do not follow up blindly. This is because the technical

11. requirements of the asphalt premix plant equipment are relatively high and its investment is also relatively high. 2. The equipment operation skills should be mastered in advance. Finally, in the production and development stage, more issues will be involved, such as power supply, emergency measures for some unexpected problems and the reliable operation of the asphalt mixing plant.
