Sigma Mixer Machine

VARADA Sigma Mixer Machines (Z-Blade Kneaders) are high-torque, heavy-duty industrial mixers designed for thorough kneading, masticating, and dispersion of high-viscosity pastes and semi-solid compounds.

Featuring two counter-rotating Z-shaped Sigma blades rotating at differential speeds inside a double U-shaped trough, generating intensive shear and compressive forces that disperse difficult additives and eliminate agglomerates.

Available with hydraulic bowl tilting or bottom screw extrusion discharge, jacketed heating/cooling troughs, and vacuum execution for bubble-free formulation of demanding materials.

Additional Information

Engineered for high-viscosity mastication, kneading, and homogenization under extreme torque loads.

Product: Heavy Duty Sigma Mixer (Z-Blade Kneader)
Working Capacity: 50 Litres to 3,000 Litres (custom models available)
Blade Configuration: Counter-rotating Tangential or Overlapping Z (Sigma) Blades
Material Construction: SS304 / SS316 / Heavy Carbon Steel contact parts
Discharge Mechanism: Hydraulic bowl tilting / Bottom screw extrusion discharge
Thermal Jacket: Jacketed trough for steam, thermal oil, or cold water
Vacuum Execution: Air-tight vacuum cover for bubble-free degassing (optional)
Drive Transmission: Heavy-duty helical reduction gear drive with safety interlocks

Benefits

  • Superior high-torque kneading and shearing forces for ultra-viscous compounds
  • Uniform dispersion of pigments, fibers, and binders with zero dead zones
  • Optional vacuum execution eliminates trapped micro-bubbles and air voids
  • Heating and cooling jacket allows precise temperature regulation during kneading
  • Smooth hydraulic tilting allows effortless and complete product discharge
  • Sturdy cast-iron and steel bedplate engineered for continuous, vibration-free operation
