Burner-heated emulsified asphalt production equipment
# Burner-Heated Emulsified Asphalt Production Equipment: Technological Innovation and Industry Applications In the field of road construction and maintenance, emulsified asphalt has become a vital branch of asphalt materials due to its energy-saving, environmentally friendly, and convenient construction features. As a core piece of equipment, burner-heated emulsified asphalt production machinery leverages advanced temperature control and optimized processes to ensure stable production and enhanced product quality. This article explores the innovative value of this equipment from four key perspectives: equipment principles, technological advantages, application scenarios, and future development trends. ## I. Equipment Principles: Synergy Between Burner-Based Temperature Control and Emulsification Process The core of emulsified asphalt production lies in blending asphalt, water, and an emulsifying agent into a uniformly dispersed emulsion through mechanical shearing. The burner-heated equipment utilizes a thermal oil circulation system to provide precise temperature control for asphalt heating, pipeline insulation, and emulsion mixing. Its operational process can be broken down into three main steps: 1. **Thermal Oil Circulation Heating**: The burner ignites diesel or natural gas to heat the thermal oil to a temperature range of 150°C–180°C. This heated oil is then circulated via a closed-loop system to transfer heat to the asphalt transition tank, emulsion mixing tank, and final product storage tank, ensuring consistent temperatures throughout the process. 2. **Asphalt and Emulsion Mixing**: Hot asphalt (110°C–120°C) is combined with preheated emulsifier solution (60°C–90°C) according to a predetermined ratio. The mixture is then fed into a colloid mill, where the gap between the rotor and stator is maintained at just 0.035–0.05 mm. High-speed shearing at 3,000–8,000 rpm breaks the asphalt into fine particles measuring 1–5 μm, which are evenly dispersed within the aqueous phase. 3. **Final Product Output and Preservation**: The emulsified asphalt is pumped out and stored in tanks, while a thermal oil coil continuously maintains the temperature to prevent asphalt particles from clumping together. Some advanced systems also incorporate electric heaters or inert gas protection mechanisms, further extending the shelf life of the finished product. ## II. Technological Advantages: Efficiency, Energy Savings, and Intelligent Automation Through innovative design and engineering, burner-heated emulsified asphalt equipment addresses critical challenges associated with traditional methods, such as difficult temperature control, high energy consumption, and uneven emulsification. These advancements translate into three key benefits: 1. **Precise Temperature Control Enhances Emulsification Quality** Traditional heating methods often lead to localized overheating of asphalt, compromising the activity of emulsifiers. In contrast, the thermal oil system employs a dual-metal bimetallic thermostat linked to an electric shut-off valve. When the asphalt temperature drops below the lower limit (e.g., 132°C), the system automatically activates heating; when it exceeds the upper limit (e.g., 138°C), the heat source is cut off, ensuring a stable reaction environment for asphalt and emulsifiers. Experimental results show that precise temperature control boosts the storage stability of emulsified asphalt by up to 40%. 2. **Energy Efficiency Reduces Operational Costs** Emulsified asphalt production only requires heating asphalt to a moderate temperature range of 120°C–140°C, significantly reducing energy consumption compared to conventional hot-mix asphalt processes that demand temperatures as high as 160°C–180°C—achieving energy savings of over 50%. Additionally, the thermal oil circulation system recycles waste heat, and when paired with a burner-based waste heat recovery unit, energy consumption can be further minimized. For instance, a major highway project utilizing this efficient burner technology achieved annual fuel cost savings of approximately RMB 150,000. 3. **Intelligent Automation Simplifies Operation Processes** Modern equipment integrates variable-frequency speed control pumps, PLC control systems, and user-friendly human-machine interfaces, enabling real-time monitoring of critical parameters such as asphalt flow rate, emulsion temperature, and colloid mill rotation speed. The system can automatically adjust mixing ratios based on these inputs. For example, Wuxi Lute Heavy Industry’s equipment supports remote monitoring and predictive fault alerts, allowing operators to manage the entire production process simply by setting parameters on a touchscreen interface. ## III. Application Scenarios: From Road Construction to Eco-Friendly Maintenance Burner-heated emulsified asphalt equipment finds extensive use in various applications, ranging from new road construction and rehabilitation to eco-friendly maintenance projects. Its versatility makes it well-suited to meet diverse operational needs: 1. **New Road Construction and Reconstruction** Emulsified asphalt is ideal for applications such as tack coats and prime coats, particularly when using cold spraying techniques that eliminate the need for high-temperature hot asphalt, thereby minimizing damage to underlying layers. 2. **Preventive Maintenance** The rapid curing properties of emulsified asphalt make it perfect for thin-layer seal coatings, effectively repairing cracks, ruts, and other pavement defects. Meanwhile, synchronous chip seal trucks utilize burner-heated asphalt to integrate asphalt spraying, aggregate spreading, and compaction into a single, highly efficient operation—boosting productivity by up to two times compared to traditional methods. 3. **Environmental Protection and Resource Recycling** Emulsified asphalt cold recycling technology allows old pavement materials, such as milled asphalt, to be mixed with emulsified asphalt and cement, creating recycled base materials. By precisely controlling the temperature of recycled materials (60°C–80°C) during the process, burner-heated equipment prevents asphalt aging caused by excessive heat, while simultaneously reducing the reliance on virgin asphalt by more than 50%.
Asphalt Emulsification Equipment
Introduction to Emulsified Asphalt Equipment: Emulsified asphalt equipment is specialized machinery designed for producing emulsified asphalt. Its key feature lies in its ability, under the action of an emulsifier and through mechanical force, to break down asphalt into tiny particles that are evenly dispersed in water, forming a stable emulsion—emulsified asphalt. This type of asphalt is primarily used in highway and urban road projects as a tack coat, bonding layer, or surface binder. It’s also widely applied in the construction industry for formulating waterproof coatings and waterproof membranes. Over the past several decades, emulsified asphalt equipment has undergone significant advancements, with an increasing variety of models and specifications, along with continually improved structural performance. Today, the technology behind these machines has reached a highly sophisticated level. In particular, the comprehensive emulsified asphalt equipment systems introduced in recent years incorporate a range of cutting-edge modern technologies, enabling them to meet the demands of producing various types of asphalt emulsions. These systems can be summarized by two main technical features: (1) High automation: The equipment features automatic control over the metering of asphalt, water emulsions, and various additives, along with automatic compensation, recording, and calibration functions. (2) Modular design for easy assembly, disassembly, and mobility: For instance, companies like Scana Road from the U.S. pre-assemble core components such as the colloid mill, control cabinet, pumps, and metering devices into standardized shipping containers. During operation, users only need to connect the necessary pipelines and power supply to get started. With the widespread adoption and promotion of emulsified asphalt slurry seal technology across China, higher demands have emerged regarding both the quality and production capacity of emulsified asphalt. As a result, emulsified asphalt equipment is evolving toward greater standardization and optimization. --- ## Performance Overview Equipment Configuration: 1.

Electric Heating Modification & Emulsification Integrated Machine
# Electric Heating & Emulsification Integrated Machine: Deep Integration of Technological Innovation and Industry Applications In the fields of road engineering and material processing, the efficiency and versatility of equipment have become core demands driving industry development. As an innovative device that integrates heating, modification, and emulsification functions, the electric heating and emulsification integrated machine is making a significant impact—thanks to its advanced features like precise temperature control and highly efficient mixing—particularly in applications such as asphalt modification and emulsified asphalt production. ## I. Technical Principles: Synergistic Innovation in Electric Heating and Emulsification Processes The core technology of the electric heating and emulsification integrated machine comprises two key modules: the electric heating system and the emulsification shear system. The electric heating module employs resistance heating technology, powered by 380V three-phase electricity to drive heating elements ranging from 36kW to 55kW. This enables the internal temperature of the equipment to reach 185°C–210°C within just 10 minutes. Such a temperature range not only meets the thermal plasticity requirements for asphalt modification but also prevents overheating or charring of the materials. For instance, the XM-20T model produced by Dezhou Xinmao Road Construction Equipment Co., Ltd. features a gas-assisted heating system that further reduces the heating time. Combined with the insulated design of its 304 stainless steel inner tank, this model achieves a thermal energy utilization rate as high as 92%. Meanwhile, the emulsification shear module relies on a high-speed rotating stator-rotor system to break down fluids. When materials enter the 200mm-diameter shear chamber, the rotor spins at a linear velocity of 800 rpm, generating shear flow speeds exceeding 15 m/s. Paired with a precision gap of just 0.1 mm between the stator and rotor, this process effectively reduces asphalt particles to below 5 μm in size. Compared to traditional colloid mills, this mechanical energy conversion method boosts efficiency by 40%, while achieving an emulsification uniformity rate of up to 98.7%. ## II. Equipment Advantages: Balancing Efficiency, Cost, and Quality Compared to conventional split-type equipment, the integrated design of the all-in-one machine delivers several notable advantages: 1. **Energy Consumption Optimization** By incorporating a heat recovery system, the machine recycles the frictional heat generated during emulsification back into the heating module, reducing overall energy consumption by 28%. For example, the XM-12T model achieves an energy consumption of only 0.35 kWh per ton of output, representing a 31% savings compared to traditional processes. 2. **Space Efficiency** The compact, frame-based structure integrates components such as the heating tank, emulsifier, and metering pump into a single 4.2m × 2.5m base unit, cutting the footprint by 65% relative to separate equipment setups. This streamlined design makes it ideal for space-constrained environments, such as mobile asphalt plants. 3. **Consistent Product Quality** An intelligent proportional control system, linked with flow sensors and a PLC controller, ensures precise regulation of the asphalt-to-emulsifier ratio with an accuracy of ±0.5%. In a recent highway maintenance project, this technology extended the storage stability of emulsified asphalt from 72 hours to 120 hours, while simultaneously reducing needle penetration index fluctuations to within ±0.2 units. ## III. Application Scenarios: Expanding Across Industries—from Road Construction to Specialty Materials 1. **Road Engineering Applications** In modified asphalt production, the integrated machine can simultaneously melt SBS polymers and emulsify the asphalt matrix. 2. **Environmental Material Development** By upgrading the stator-rotor components to Hastelloy alloy, the equipment becomes capable of handling high-viscosity rubber-asphalt mixtures. 3. **Customized Specialty Asphalts** To meet the demands of colored pavement applications, the machine can be equipped with an online pigment addition system.
