  • Patent number: 9803099
    Abstract: An aqueous carbon black millbase, an aqueous carbon black liquid coating, and a method of making the millbase and liquid coating are provided. The carbon blacks are modified carbon blacks that are engineered to be able to be stirred into an aqueous vehicle without high energy milling of the carbon black. The modified carbon blacks include low organic treatment levels and the millbase and liquid coating do not require large quantities of dispersant. The resulting coatings exhibit excellent viscosity, color, hiding power and stability.

  • Patent number: 9475057
    Abstract: Some of the embodiments described herein relate to liner elements such as lifter bars that can be used in grinding mills. In one example, a lifter bar has a top elastomeric layer and a bottom elastomeric layer, the composition of the top elastomeric layer being different from that of the bottom elastomeric layer. In another example, a lifter bar is constructed from carbon black-reinforced natural rubber and has a leading face and a protrusion at a top region of the leading face. In a further example, a lifter bar is fabricated from carbon black-reinforced natural rubber and has a leading face geometry such that face angle ? remains 25° or less over an operational period measured form the time the lifter bar is new, until the height of the lifter bar is reduced by a certain amount, e.g., by 80%.
