500 Liters Sigma Mixer

It is offered with a 40 H.P. motor for general duty and a 50 H.P. motor for heavy-duty applications. Voltage can be customized to match the customer’s local power supply requirements.

The mixer is built from heavy-duty Mild Steel, Stainless Steel 304, or Stainless Steel 316. Surface finishes range from matte to mirror polish, and Mild Steel versions receive a red-oxide primer plus dual-layer epoxy paint for protection.

It uses two counter-rotating precision-crafted tangential Z-profile (sigma) blades that create differential-velocity longitudinal displacement, intense shearing, folding, stretching, and kneading action against the trough walls, ensuring uniform homogenization with minimal product retention.

Discharge can be performed via manual hand-wheel tipping, automated hydraulic actuation, bottom-mounted drainage valves, or a lateral extrusion screw positioned beside the mixing container for controlled unloading.

Yes. The mixer can be fitted with adaptable thermal jackets for external heating or cooling (steam, hot oil, electric, or water), high-density mineral wool insulation, and protective metal cladding. Optional blade cooling is also available.

Tangential blades meet at the edges and typically run at a 3:2 speed ratio; they are preferred for high-viscosity materials (adhesives, rubber compounds, pigments). Overlapping blades rotate at the same speed and suit lower-viscosity free-flowing or creeping products (creams, pastes, ointments), providing gentler shearing and faster inter-compartment transfer.

It is widely applied in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries for intensive kneading and homogenization of sticky, high-viscosity formulations.

Ultra-close clearance between the trough wall and agitators, resilient PTFE shaft seals (food-grade compatible), heavy-gauge construction, and optional vacuum or liquid-spray systems help eliminate retention, ensure hygiene, and handle abrasive or sticky media effectively.

It delivers homogeneous blends faster than conventional mixers, significantly reduces batch-to-batch variation, handles large volumes while maintaining quality, withstands continuous heavy-duty use with low maintenance, optimizes power consumption through efficient blade and drive design, and features a tilting bowl plus accessible layout for easy cleaning between batches.
