A chemical milling process to produce water-based inkjet
In this study, a chemical milling process is developed to convert carbon residues from pyrolyzed waste tires into valuable water-based inkjet printing inks. The residues after waste tire pyrolysis were first sieved to remove ash components and ground into powder (~80 μm). The resulting waste tire carbon blacks (TCB) processed by regular dry or

Reducing Biochar Particle Size with Nanosilica and Its
Although biochar can approach carbon black in terms of carbon and ash content, substituting carbon black with biochar typically degrades the mechanical properties of rubber composites because of the much larger particle size of biochar. Biochar is produced from biomass and must be size reduced by “top-down” methods such as milling.

Two most common types of ash: high-carbon black ash, left, and low-carbon gray ash, right. Plate 5. A spreader equipped with a grate or screen on the top can be used to remove large particles from the ash. Plate 6. A wide opening in the spreader—24 to 28 inches (61 to 71 cm) wide, as shown here—allows ash to feed
