10,000-ton continuous production line for natural rubber/white carbon black wet mixing

  • Overview:

    Thiscontinuous production line is certified by CPCIF (China Petroleum and ChemicalIndustry Federation). We took the lead to realize 10,000-ton continuousproduction line for natural rubber/white carbon black wet mixing in the world. Thisis not only a major technical breakthrough in natural rubber industry, but alsoa reform for the rubber mixing, which is the most energy-consuming step inrubber processing. This is a new path for green manufacturing of tires.

    Thiscontinuous production line is certified by CPCIF (China Petroleum and ChemicalIndustry Federation). We took the lead to realize 10,000-ton continuousproduction line for natural rubber/white carbon black wet mixing in the world. Thisis not only a major technical breakthrough in natural rubber industry, but alsoa reform for the rubber mixing, which is the most energy-consuming step inrubber processing. This is a new path for green manufacturing of tires.



    This production line employs a new non-acidflocculation method based on dynamic ratio of continuous liquid materials’feeding, which realizes continuous production. This method saves 50% waterconsumed than traditional technique. The flocculating time is shortened from 5hours to 30 seconds. The occupied area is 20% less than traditional. Besides, screwextruder and continuous dehydration/granulation machine are integratedtogether. The result is moisture content of rubber at the outlet is below 30%,and loss rate of white carbon black is below 2%.

     

    The extraordinary feature of thisproduction line is high ratio of white carbon black in the tires, which offersa practical method to produce green rubber for tires. It is the integration of continuousliquid mixing of rubber & additives, quick flocculation, screw extruderwith dehydration/granulation machine, continuous microwave drying and other newtechnology. It’s the first time to build the 10,000-ton continuous productionline for natural rubber/white carbon black wet mixing in the world. It canproduce wet mixed rubber with white carbon black 10~90phr.

     

    Rubbermixing is the most energy-consuming step in rubber processing, which takes 40%of total energy cost. And traditional dry mixing technique requires about400kWh for each ton of rubber mixed. However, using our new technology, theenergy cost will be lowered by 15~30%, which is at least 60kWh for each ton ofrubber mixed. Furthermore, the white carbon black is uniformly dispersed in therubber, which improves the rubber quality and reduces the dust pollution.
