Real shot JCT Sigma Blade Mixer

1、Definition
The sigma blade mixer operates by utilizing a pair of sigma-shaped blades that rotate in opposite directions within a cylindrical mixing chamber. These blades intermesh as they rotate, creating a shearing and kneading action. This continuous movement effectively mixes and kneads high-viscosity materials by subjecting them to both cutting and folding forces. The dual-direction rotation ensures thorough blending, while optional features like vacuum or jacketed operation can be employed to enhance specific processes.

2、Main Structure
Mixing Chamber: The cylindrical chamber where the mixing process takes place, often constructed from durable materials like stainless steel.
Sigma Blades: Two horizontal, sigma-shaped blades that are counter-rotating.
Drive Mechanism: A motor-driven system that powers the rotation of the sigma blades.
Optional Features: Some mixers may include features like a vacuum system, a jacket for temperature control, and mechanisms for material loading, discharge, and cleaning.

3、Functions
Mixing and Kneading: Their primary function is to mix and knead high-viscosity materials effectively, ensuring a uniform blend. They are essential for processes such as rubber compounding, adhesive formulation, and dough preparation.
Shearing and Folding: The sigma blades generate shearing and folding forces that break down and distribute components within the mixture, promoting homogeneity.
Temperature Control: Many sigma mixers have a jacketed design, allowing for temperature control during mixing, which is vital for processes that require heating or cooling.
Vacuum Mixing: Some models can operate under vacuum conditions, which is useful for removing air bubbles from the mixture in applications like rubber compounding.
