Asphalt modification equipment Performance and details of modified asphalt equipment:

The road surface paved with modified asphalt has good durability and wear resistance, and it can realize emulsified asphalt that does not soften at high temperature and does not crack at low temperature. The excellent performance of the modified asphalt equipment comes from the modifier it adds and the colloidal mill that is advanced in various places; the modifier can not only combine with each other under the action of temperature and kinetic energy, but also react with the asphalt, thus improving the quality of the asphalt. At the same time, under the action of the high-speed rotating colloid mill, the molecules of the modifier are cracked to form a new structure, which is then sprayed onto the mill wall and bounced back, and evenly mixed into the asphalt.

Modified asphalt equipment

The production of SBS modified asphalt consists of three major parts: swelling, grinding, and inoculation, requiring accurate proportioning, reliable control, fine and uniform grinding, prevention of segregation, and local and overall aging. Therefore, our equipment is based on the advanced assembly line process, with the high-speed shear homogenizing mill as the core, and the automatic control system combined with the human-machine interface and PLC, automatic constant temperature system, automatic weighing and adding system, etc. , combined with a reasonable formula design, to offer you a set of optimized and user-friendly SBS modified asphalt complete equipment, which consists of the following five parts:

1. Fuel heat transfer oil constant temperature automatic control system:

The processing of SBS modified asphalt is carried out within a certain temperature range. In order to ensure that the constant temperature is within a certain range, domestic high-quality heat transfer oil boilers, pneumatic valves, temperature controllers, and heat transfer oil are used. The temperature in each asphalt tank is automatically controlled within the required range through the automatic combustion and stop of the boiler, the circulation of heat transfer oil, and the automatic opening and closing of the pneumatic valve.

2. SBS, asphalt metering control system:

Strict proportioning is one of the important conditions to ensure the production of qualified modified asphalt. The proportioning accuracy of SBS and matrix asphalt can be guaranteed through instrument setting and PLC interlocking control. In the metering conveyor, the weight signal of the SBS is fed back to the PLC at high speed through its counting device, and is continuously compared with the set value; the matrix asphalt passes through the flow meter under the action of the asphalt pump, and the flow meter feeds back the flow signal to the given value The controller is constantly compared with the set value. In the program, the anti-heavy addition, non-addition, and less-adding program segments are set. Each swelling tank must be fed according to the given formula, otherwise it will not be automatically converted.

3. High-speed shear homogenizing mill, super mill

This is the core equipment of the complete set of equipment, which has a high chance of shearing. It first sends the SBS asphalt mixture into the high-speed rotating grinding discs through the absorption and stirring of the inlet screw, and is subjected to countless times in numerous grinding teeth and grooves. The shearing and grinding are integrated, and the modified asphalt produced after 2-3 times of grinding fully meets the JTG F40-2004 standard.

4. Automatic control system

The whole production process is controlled by industrial computer and PLC imported from Japan. The production process is intuitively and vividly displayed on the screen, which can dynamically reflect the changes in the production process. Necessary interlock protection, automatic alarm protection, daily output and monthly output are set. Printing, recording, liquid level display and control, etc. In order to increase the reliability of the whole system, a manual button operation part is set in the system.

5. The production process of the assembly line

The complete set of equipment consists of 2 batching tanks, 1 buffer, 3 incubating tanks, 1-2 high-speed shear homogenizing mills (super mills), coupled with pipelines, valves, etc. to form an assembly line production device. The working process is as follows: base asphalt and SBS are sent to two batching tanks after being measured and proportioned for stirring and mixing. After 10-20 minutes, they pass through the 1# mill to the buffer, and then pass through the 2# mill to the inoculation tank for development. At this time, additives such as stabilizers can be added to the incubating tank to improve the performance of SBS modified asphalt. After development, SBS modified asphalt is sent to the mixing building through the asphalt output pump or to the finished product tank. Material, one side of the material, to achieve assembly line production.

Features of modified asphalt complete sets of equipment:

It can be used in conjunction with asphalt storage, asphalt mixing equipment, etc.

Technical analysis of modified asphalt equipment:

The main processing and production equipment of modified asphalt equipment includes colloid mill and high-speed shearing machine, and there are two corresponding production processes. Modified asphalt equipment colloid mill production process. It adopts high-temperature colloid mill for primary grinding and high-temperature development of finished product tanks. SBS, stabilizer, etc. are mixed with the base asphalt in proportion, and then directly enter the colloid mill for grinding, and then enter the finished product tank for high temperature development until it is qualified.

Modified asphalt equipment high-speed shearing machine production process. Using high-temperature swelling and shearing process, the SBS and base asphalt are first mixed and swelled at high temperature, and then sheared with a high-speed shearing machine. After meeting the product quality requirements, it is sent to the finished product tank for cooling and storage.

Advantages of modified asphalt equipment:

Easy to use: The efficient spreading of emulsion requires advanced equipment, such as a spreader. Modified asphalt equipment proposes that small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack joint filling, etc., a small amount of cold mix only needs basic The equipment will do. For example, a watering can with a baffle and a shovel can do small area sealing and crack repair, and applications such as pouring pothole repair methods to fill road potholes are simple and easy.

What are the advantages of modified asphalt equipment in production:

1. Energy saving

The kerosene content in diluted asphalt can reach 50% of the maximum, while that in modified asphalt equipment only contains 0-2% of the maximum. This saving behavior is of great value in the production and utilization of white fuel. Only by increasing the light oil solvent to reduce the viscosity standard of asphalt, the asphalt can be poured and spread, and it is hoped that the used light oil can volatilize into the atmosphere.

2. Versatility

There are many application methods for modified asphalt equipment, and the appropriate method needs to be selected during application. Modified emulsified asphalt equipment reminds that the same emulsion can be used for large-scale sealant spreading, and can also be used for small-scale pothole repair work. Because they can be stored in tanks for a long period of time, they are easy to use when used in remote areas.
