Laboratory Carbon Kneader Mixer High Temperature Pitch Kneading Machine

Product Overview

This high-temperature carbon kneader provides precision thermal blending for carbonaceous powders and viscous binders such as pitch, tar, and synthetic resins. Engineered specifically for research institutions, chemical engineering laboratories, and advanced materials centers, this unit replicates industrial carbon paste kneading at a controlled benchtop scale. The equipment ensures consistent shear distribution, binder coating, and temperature uniformity to support empirical research and pilot production trials.

Designed to handle complex paste formulations, the system utilizes differential dual-blade agitation to generate intense compressive and shearing forces. This mechanical action guarantees that micro-sized carbon fractions, synthetic graphite, and calcined coke particles are thoroughly wetted and encapsulated by the liquefied binder matrix. The heavy-duty mixing chamber withstands extreme viscosity changes throughout the pre-heating, kneading, and cooling phases of material preparation.

Engineered with an emphasis on thermal stability and operator safety, this kneading system features an advanced jacketed thermal oil heating mechanism capable of achieving operating temperatures up to 400°C. Its robust stainless steel construction, integrated reverse-motion drive, and automated tilting discharge provide research teams with repeatable experimental results and effortless material handling under demanding metallurgical and chemical conditions.

Key Features

• Differential High-Shear Agitation: Features dual Z-shaped (Sigma) blades rotating at differential speeds (fast blade at 44 r/min, slow blade at 27 r/min) to generate continuous lateral and longitudinal shear stresses for complete binder distribution.
• Bidirectional Agitator Rotation: Equipped with forward and reverse drive logic to prevent material bridging, dead zones, and agglomeration along the chamber walls during highly viscous mixing cycles.
• High-Temperature Thermal Oil Jacketing: The sealed jacket configuration utilizes an array of high-efficiency electric heating elements (0.8 kW × 3) immersed in thermal oil to ensure uniform heating up to 400°C without localized hot spots.
• Automated Discharge Mechanism: Incorporates an automated discharge system that tilts the vessel cleanly, streamlining sample collection and minimizing operator exposure to hot carbon paste residues.
• Corrosion- and Wear-Resistant Contact Surfaces: All wet parts and internal vessel walls are fabricated from premium-grade stainless steel to resist mechanical erosion from abrasive carbon aggregates and chemical corrosion from volatile pitch vapors.
• Heavy-Duty Structural Rigidity: Built with a reinforced structural frame weighing 320 kg to isolate operational vibration and ensure mechanical stability during peak kneading torque demands.
• Precision Atmosphere Containment: Sealed vessel cover minimizes the escape of volatile organic compounds (VOCs) and hazardous pitch fumes during high-temperature kneading trials.
