SIGMA MIXER 350 LTRS

About SIGMA MIXER 350 LTRS

The 350 L Sigma Mixer is designed for mixing, kneading, crushing, dispersing, grinding, and drying of high-viscosity pastes that cannot be handled by standard powder mixers or liquid blenders.

It is a vital machine in the chemical, pharmaceutical, and food industries, providing:

• Uniform mixing with no dead corners
• Efficient kneading using dual sigma blades running at differential speeds
• Durable construction with stainless steel contact parts ensuring consistent product quality

Working Principle

• Materials are rubbed, folded, pressed, and pushed between the sigma blades and container walls.
• Continuous end-to-end circulation guarantees homogeneous processing.
• Two sigma blades are tangent and rotate at different speeds, ensuring efficient kneading.
• Discharge is performed by tilting the container via a manual wheel and worm pinion mechanism (with other discharge systems available).

Construction Features

• Contact Parts: Stainless Steel (SS304 / SS316) for product quality and corrosion resistance.
• Jacket: Provided for heating or cooling applications.
• Vacuum Design: Available on request, equipped with side glass and light glass for process monitoring.
• Discharge Options:
• Tilting by manual wheel with worm-pinion
• Screw motorized mechanism
• Hydraulic cylinder with power pack
• Bottom valve discharge
