SIGMA MIXER 550LTRS

About SIGMA MIXER 550LTRS

The 550 L Sigma Mixer is engineered for mixing, kneading, crushing, dispersing, grinding, and drying of high-viscosity pastes that cannot be processed effectively by standard powder mixers or liquid blenders.

It is a key equipment for chemical, pharmaceutical, and food industries, offering:

• Uniform stirring with no dead zones
• High-efficiency kneading through dual sigma blades operating 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 of material ensures homogeneity.
• The two sigma blades are tangent and rotate at different speeds to achieve efficient kneading.
• Material discharge is done by tilting the container via a manual wheel and worm pinion mechanism (other discharge options 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, with side glass and light glass for process observation.
• Discharge Options:
• Tilting by manual wheel with worm-pinion mechanism
• Screw motorized discharge
• Hydraulic cylinder with power pack
• Bottom valve discharge
