TriVolution Tri-Kneader

Product catalog summary
Introduction
The TriVolution Series Tri-Kneader is designed to address challenges in chemical processing, such as cost, sustainability, and efficiency. Developed by B&P, it leverages over 100 years of engineering experience to offer a high-precision compounding system.

Specifications
The TriVolution features a PowerStrokeTM gearbox for high torque and low maintenance, a torque limiter coupling to prevent overload, and an AC motor with a variable frequency drive. It includes a sealed process zone, a three-way hydraulic barrel hinge system, and various feeding options. The system supports multi-stage mixing and efficient devolatilization through atmospheric or vacuum vent stacks.

Operating Principle
The TriVolution operates on multiple axial oscillations per screw shaft revolution, enhancing mixing through a slalom pattern around stationary pins. This design allows for adjustable shear rates and efficient distributive and dispersive mixing, reducing mechanical energy requirements by up to 60% compared to traditional systems.

Performance and Efficiency
With a minimum L/D ratio of 8:1 and a maximum of 20:1, the TriVolution requires less energy than twin-screw systems. It maintains stable temperatures and low specific mechanical energy (SME) even at increased RPMs, offering high throughput and reduced operational costs.

Flexibility and Capacity
The TriVolution series offers models with screw diameters ranging from 30mm to 160mm, supporting various process speeds and drive capacities. It is suitable for a wide range of applications, including thermoplastics, thermosets, and specialty compounds.

Application Areas
The TriVolution excels in compounding masterbatches, PVC, Sioplas, semiconductive materials, fiber-reinforced compounds, and TPO/TPE. It offers high dispersion and torque capabilities, making it suitable for challenging formulations.

Testing and Demonstration
B&P's Customer Development and Demonstration Center provides comprehensive testing facilities to evaluate products and processes on a pilot scale. The center supports empirical analysis and optimization of compounding systems.

Conclusion
The TriVolution Series Tri-Kneader offers a versatile, efficient, and high-performance solution for chemical processors. B&P guarantees performance and provides dedicated support for installation and operation, ensuring customer satisfaction.

TriVolution Tri-Kneader-4

TriVolution Operating Principle TriVolution is a unique compounding system based upon multiple axial oscillations per revolution of the screw shaft. The mixing interaction occurs between the discontinuous flights of the screw and stationary pins positioned along the interior barrel wall. The flights weave in a slalom pattern around the pins. A repeating cycle of product separation, folding, compression, shear, decompression and reorientation. In legacy kneaders, the pin-flight interaction occurs as a fixed spike pattern with a peak shear moment. TriVolution dramatically improves upon this interaction...

PVC compounding Product degrades at 200ºC. Legacy Kneader burned product resulting in SME dropoff. TriVolution maintains stable temperature and low SME despite increased rpm and throughput. High-Performance , High-Efficiency High throughputs were achieved at a much lower rpm than with the legacy technology. While the TriVolution is also capable of high rpm, processing at slower circumfirential screw tip speeds lessens the wear and tear on the machine. Longer operational life, higher availability, less downtime and fewer replacement parts means lower operational expense per pound of material produced....

TriVolution Application Areas Ranging from the very aggressive, high-energy, high-shear dispersive nature to a rather finesse, low-shear, distributive nature, TriVolution is a premium compounder across a very broad spectrum of application areas. A significant percentage of tests performed at B&P were on formulations that processors were not able to compound by conventional means. A cross-section of application areas relevant to target markets are represented here. Layouts, parameters and performance are dynamic according to material and formulation specifics.

SIOPLAS: An excellent combination of adjustable residence time distribution and distributive mixing profile support the performance of TriVolution in XLPE and Sioplas applications. TriVolution is proven to acheive a high level of grafting to the polymer matrix. A well-controlled low temperature profile prevents the flashing off of liquid component. High dispersion SureFlite-24 elements from the compounders toolbox allow the polymer to be quickly melted prior to the introduction of liquid silane/peroxide mixture. SEMICONDUCTIVE: Split-feeding special conductive carbon-black under a high-dispersion...

Additives Filler TPO/TPE and SPECIALTY: TriVolution incorporates several mechanical steps into its mix cycle and it repeats this cycle several times throughout the rotation and reciprocation of the screw shaft. Conveying, folding, orientation, compression, shearing, decompression and reorientation take place and, unlike traditional systems, the intensity of each cycle is adjustable. Control and consistency are primary advantages of TriVolution and a very uniform dwell time and heat history can be presented resulting in high quality compounding of a wide range of materials.
