Smc Compound Sigma Mixer

Two heavy-duty, interlocking sigma-shaped (Z-shaped) blades rotate in opposite directions inside a W-shaped mixing trough, usually at different speeds. This creates intense shearing, folding, compressing, and kneading actions that thoroughly disperse additives, break down agglomerates, and produce a homogeneous blend.

It handles polyester resin pastes, fillers (such as calcium carbonate), chopped glass fibers, pigments, and additives used in SMC/BMC/DMC production. It is also widely used in rubber, plastic, chemical, adhesive, food processing, pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, and cosmetic industries for high-viscosity compounds.

The mixer is manufactured from Mild Steel, SS 304, or SS 316. Surface finishes can be customized from matte to mirror-gloss polish. Mild steel units receive an anti-corrosive red oxide primer followed by dual epoxy paint coats. PTFE shaft seals provide sanitary, food-grade compatibility.

Precision-engineered tangential Z-shaped blades with ultra-tight clearance to the trough walls eliminate product retention. Jacketed troughs allow heating or cooling, high-density mineral wool insulation with

Models range from ASM-50 (approx. 50 L working / 80 L gross capacity, 5–7.5 HP) to ASM-3000 (approx. 3000 L working / 3800 L gross capacity, 100–120 HP). Intermediate sizes and both general and heavy-duty motor variants are available; voltage can be customized to local requirements.

Discharge options include manual hand-wheel tilting, automated hydraulic tilting, bottom-mounted outlet valves, or a lateral extrusion screw. These configurations suit different viscosities and production preferences, making unloading of sticky materials efficient.

Yes. Integrated temperature-regulation jackets support external heating or cooling. The trough is insulated with high-density mineral wool and clad externally. Optional blade cooling arrangements are also available for temperature-sensitive processes.

Available options include a liquid spray system, vacuum system (for de-aeration), blades cooling arrangement, screw/extrusion system, and automatic valve discharge system. Specialized modular configurations can be supplied on request.

Its dual-blade design delivers superior shearing and kneading action that standard mixers cannot match, ensuring uniform dispersion of glass fibers, fillers, and resins into a homogeneous dough-like mass. This results in consistent quality, reduced mixing time, and reliable performance for demanding composite and industrial applications.
