Excellent dispersion and productivity while providing energy efficiencies.
Highly filled masterbatch, also known as natural or calcium masterbatch, contains high concentrations of calcium carbonate (CaCO3) or talc in the polymer base. These fillers modify polymer properties, for example, making a compound more structurally sound, and help to reduce costs by using a higher fill level.
Farrel Continuous Mixers are designed to address the many challenges of processing highly filled masterbatch including:
A single-entry feed port and efficient rotor feed flight conveying capacity enable a high volume of material intake and processing
The 6 L/D rotors allow for additional energy cost savings due to the short residence time and lower specific energy imparted into the materials, while the unique rotor geometry ensures optimum dispersion of the filler into the polymer
The high free volume mixing chamber allows for maximum filler levels and material circulation
Separate and independent mixing and pressurization, or extrusion, functions ensure each process is performed at optimum conditions resulting in low specific energy input (SEI)
A variety of production sizes to meet large throughput requirements for economies of scale and productivity
