1.Thermal oil heating constant temperature control system

The production and processing of SBS modified asphalt must be carried out within a certain temperature range, which is determined by experiments with different grades of asphalt. Matching domestic high-quality thermal transfer oil heating furnace, pneumatic valve, temperature controller, heat-conducting oil, burner and program controller imported from Germany or Japan adopted to ensure the constant temperature control. Through automatic combustion and stop of heating furnace, circulating of heat-transfer oil, automatic opening and shutting of pneumatic valve, the heat is sent to each heating part and set by the temperature controller, so as to achieve temperature control automation.  

2.SBS, base asphalt ratio control system

Strict proportioning is one of the important elements to ensure the production of qualified modified asphalt. The precision of the proportioning of SBS and base asphalt can be ensured through the setting of the instrument and the interlocking control of PLC. The details are as follows:

After the SBS is broken, the weight is measured and sent to the weighing indicator or PLC, where the weight of the SBS is given and controlled. Base asphalt passes through the flowmeter under the action of the asphalt pump, flow signals of the base asphalt sent and converted into a weight signal; SBS and asphalt are added equally under the control of  the PLC program, and the accuracy of both is 0.5 level. 

3.High-speed shear homogenizing mill

4.Automation control system

5.Advanced and reasonable production process

6.Stabilizer, additives adding system

In order to meet the needs of different asphalt processing, complete set of equipment can be equipped with stabilizer adding device and auxiliary agent adding device. After the stabilizer is metered, the pump is directly added to the swelling tank. After grinding and reaction, the SBS particles and the asphalt can be combined tightly together, they can prevent segregation for a long period of time. The additives are added to the incubation tank after being metered when needed, which can effectively improve the performance indexes of the modified asphalt.
