This article highlights the key advantages of kneading machines in processing high-loading pigments such as carbon black and high-oil-absorption colorants. Compared to twin screw extruders, kneading machines offer superior pigment wetting, better dispersion uniformity, and greater process flexibility due to their adjustable low-shear mixing capabilities. They are especially effective in applications requiring extended mixing times and can be combined with twin screw extruders for optimized results. Kneading machines are widely used in producing high-end masterbatches, conductive materials, and specialty coatings, offering enhanced product quality and energy efficiency.
