Z Type Sigma Mixer

The mixer uses tangential or overlapping ‘Z’ type blades that rotate toward each other (often at differential speeds, e.g., 3:2 ratio in tangential designs). This creates bulk movement, stretching, folding, dividing, recombining, and shearing actions against the trough walls, transferring material from one end to the other while reducing solid particle size for uniform blending.

It excels with high-viscosity formulations such as dense pastes, creams, ointments, adhesives, rubber compounds, flush colors, dyes, pigments, carbon pastes, clay coatings, and specialty chemicals. It is widely used in Pharmaceutical, Nutraceutical, Herbal, Ayurvedic, Biotech, Cosmetic, and Chemical industries.

Models range from ASM-50 (50L working / 80L gross) to ASM-3000 (3000L working / 3800L gross). Motor power starts at 5 HP (general) / 7.5 HP (heavy duty) for smaller units and goes up to 100 HP / 120 HP for larger ones, with customization available up to 250 HP and support for various power voltages.

The trough can be jacketed for heating (steam, hot oil, hot water, or electric) or cooling (chilled water circulation). Mineral wool insulation with cladding is available for energy efficiency. Optional cored blades and blades cooling arrangements provide additional temperature control for sensitive materials.

• Tangential ‘Z’ blades: Best for higher-viscosity materials (e.g., adhesives, rubber) with strong kneading/shearing; front blade typically rotates faster.
• Overlapping blades: Suited for lighter viscosities (e.g., creams, ointments) with faster material interchange but lower kneading intensity. Other options include spiral or Naben blades.

Discharge options include manual hand-wheel tilting, hydraulic automatic tilting, bottom valves, extrusion screw systems, and automatic valve discharge. These are designed to handle viscous products smoothly and minimize waste.

Key options include Liquid Spray System, Vacuum System, Screw System (feeding/discharge), Blades Cooling Arrangement, Automatic Valve Discharge, variable speed drives (VFD), overload protection, and custom sealing (PTFE for food-grade use).

It features high-grade Stainless Steel 304/316 construction with matt/mirror polish, PTFE/silicon shaft seals, minimal gap between trough and blades to prevent sticking, smooth surfaces for easy cleaning, and jacketed temperature control—making it suitable for regulated pharmaceutical, nutraceutical, and food applications.

Highly customizable in trough thickness, motor HP (1.5–250 HP), blade types, discharge methods, heating/cooling systems, feeding mechanisms, sealing materials, finishes (matt/mirror or epoxy paint), and voltage configurations. This allows tailoring to diverse viscosities, batch sizes, and regulatory requirements.
