Type SG series modified asphalt equipment is my company after modification of the various domestic and imported processing equipment comprehensive performance analysis and contrast to gather many long, combined with our company for 20 years in the asphalt transportation, polymer modified asphalt grinding, finished product storage area accumulated rich experience, through continuous improvement and perfect after a high quality, high reliability of the modified asphalt processing equipment.High degree of automation, simple operation, clear interface flow, other polymer modified asphalt processing functions reserved for the equipment.

Modified asphalt complete set of equipment composition

SG series of modified asphalt equipment suitable for the production of a variety of polymer modified asphalt, modifiers can be SBS, SBR, EVA, PE, etc...

The equipment is mainly composed of swelling stirring, instantaneous temperature rise, measurement, grinding, finished product incubation, electrical control and other systems.
 

Swelling stirring system

This equipment adopts the circulating heating mode of channel steel heat conduction oil outside the swelling mixing tank. Through the specific design of the tank body and the stirring blade slurry, there is no dead Angle in the tank, and the tank is sufficiently stirred without plugging.The agitator adopts grease lubricated cycloidal needle wheel reducer, which has high output efficiency, strong anti-environment ability and long maintenance cycle.The tank is equipped with a pressure sensor designed by our company for high temperature and high viscosity liquid level detection. The human-computer interactive operation interface can visually observe the liquid level status in the tank. The tank body is equipped with temperature sensor, liquid level limiter, valve signal sensor and other functions, with high safety performance.

Heating system

The system consists of asphalt pump, frequency converter, temperature sensor, heat exchanger, and the corresponding of valve pipe, under the automatic constant temperature program control, according to the temperature sensor measuring the heat exchanger of import and export temperature difference comparison, through the PID closed-loop control, the asphalt pump the infinite frequency conversion adjustment, in order to achieve constant output of asphalt set temperature, asphalt airtight environment under elevated temperature in a short time, won't produce asphalt aging phenomenon.

Metering system

The measurement of asphalt is measured by high precision asphalt flowmeter, and the mechanical data of flow meter counter is converted into impulse electric signal. The pulse signal received by PLC is calculated by high speed counter, and the set asphalt value is reached to stop the feed asphalt pump automatically.Modifier composed of metering tank and weighing module, weighing module of signals through the amplifier amplification, calculated by the program of PLC receives the amplified signal, set the required amount, to the set value automatically stop, auxiliary measurement and measurement, asphalt, according to the need to add the complete process automatically into the next feeding program.

Grinding system

Reasonable to add high viscosity modified asphalt mixture delivery pump with two high-speed shear colloid mill series, modified asphalt grinding system, a grinding after two grinding machine twice high-speed shear grinding can achieve ideal effect, specifically for high shear grinding motor, stator to design new asphalt mixture in the grinding chamber, z-shapge motion mode of asphalt mixture in a very short period of time for cutting and grinding, countless times modified asphalt refining and production efficiency.

Control system

The man-machine interactive operation interface developed by imported PLC+ force control configuration is adopted. The working interface includes asphalt temperature of matrix, real-time display of asphalt metering, real-time display of modifier metering, dynamic liquid level display, real-time display of auxiliary metering, and intuitive display of process flow production. The operation interface is clear and clear.Set a maximum density of asphalt modification, liquid level alarm control, mill pump and high-speed shear grinding machine is equipped with frequency converter, through the PLC control automatic regulating current, the system data can be set, all production batch data automatically preserve, convenient query, production statements printing function, continuous production line production process, high production efficiency, stable and reliable performance.

Finished product incubation system

The prepared modified asphalt is stored in the finished product incubator tank, and is continuously stirred and inoculated. The stabilizer through the test formula is added to ensure the modified asphalt has good thermal storage stability.

Introduction to modified asphalt

The modified asphalt can be made from polymer, natural asphalt and other modified materials. The quality of all kinds of polymer modified asphalt should meet the technical requirements in the table. When using the polymer other than the list and the compound modified asphalt, the technical requirements can be formulated through experimental research.et the technical requirements in the table. When using the polymer other than the list and the compound modified asphalt, the technical requirements can be formulated through test research.

Technical requirements for modified asphalt

Note
135 °C motion viscosity can be used in the table of the highway engineering asphalt and asphalt mixture test regulations (JTJ052-2000) in the”asphalt cloth type rotary viscosity test method (bullock anfield viscometer method)" are measured.If it is easy to pump and mix the modified asphalt without changing the physical and mechanical properties of the modified asphalt and meeting the safety conditions at the temperature, or it is proved that the quality of the modified asphalt can be guaranteed when the pump and mix temperature are appropriately increased, and the construction is easy, and the measurement is not required.
 

The storage stability index is applicable to the finished product modified asphalt produced in the factory.The modified bitumen produced on site has no requirement for storage stability, but it must be continuously stirred or pumped after production to ensure no obvious segregation before use.
