Revolutionizing tire compound manufacturing: how continuous milling delivers competitive advantages

Continuous milling is an economical and gentle method for processing technical rubber using two-roll plasticizer (TRP) technology. This process combines cracking, homogenizing and discharging in three zones along the continuous roll. The rubber specialized roll design provides the axial material transport under controlled temperature. The reproducible homogeneity of the material is adjusted by different speeds and frictions. The machine allows an automated process and easy maintenance. The benefits include viscosity reduction, a decrease in energy consumption of up to 50% and less floor space demand. Established in tire production, this technology is adaptable for various rubber processing needs and sustainable materials.
