Sigma Blade Mixer - U-shaped Trough Design, Counter-rotating Blades For Efficient Cross Mixing And High Shearing Effect

The Sigma Blade Mixer is having a W a shape trough and includes two blades that rotate towards each other at differential speeds. Each blade moves material in opposite directions and at differential flow rate in turn provides efficient cross mixing. The blade rotate maintaining close uniform tolerances

between blade and trough inner surface. Due to minimum clearances between blade and trough wall it creates high shearing effect in material and size reduction of solid materials.

Discharging of kneader is generally done by tilting the trough by means of screw- Nut or gearing mechanism or by hydroelectric operation.

The kneader extruder includes two counter rotating kneading blades and discharge screw. The blades are provided in horizontal axis on both sides of U shaped. trough. Screw is provided in cavity below blades and parallel with blade axis.

During mixing both blades rotate opposite to each other and screw rotates in reverse direction. Constantly feeding materials in the mixing blades.

During discharging operation, screw rotates in reverse direction pushing material outside from trough towards discharge port
