Particle Coating

The SIERRA pin mill forms the heart of Ecutec's E-COAT, a unique solution for the coating of ultrafine powders. This system is most commonly used for coating calcium carbonate with stearic acid to meet the requirements for fillers used in the plastics industry.  The SIERRA's proprietary injector design achieves a high degree of atomization of the coating fluid, while the high tip speeds produced by the counter-rotating pin disks provide the high shear forces required for proper dispersion and uniform coating. Each coating system is custom designed for the application and includes all auxiliary equipment such as heating systems, melting tanks, dosing controls, pumps, fans, filters and advanced monitoring equipment to ensure efficient, consistent coating results. Because of its unmatched efficiency the E-COAT system consumes less power and fluid than any other method in use today. Compared to these other methods the E-COAT consumes 30% less energy and 20% less fluid for the same product quality and production rate.
