Adhesives Sigma Mixer

The mixer offers tangential (Z-blades running parallel at differential speeds, ideal for high-viscosity adhesives, rubber compounds, and pigments for strong kneading/shearing) and overlapping/intermeshing designs (blades that mesh for gentler action on lighter viscosities). Tangential configuration is typically preferred for adhesives due to superior shear and material transfer.

Models range from lab/pilot scale (ASM-50: 50L working / 80L gross) up to large production (ASM-3000: 3000L working / 3800L gross). Motor options vary from 5–7.5 HP (general) to higher heavy-duty ratings, with power voltage customizable to local requirements. Fill volumes are typically 40-65% of trough capacity.

The mixing trough includes an optional jacket for heating (steam, hot oil, hot water, or electric) or cooling (chilled water), with mineral wool insulation and cladding for efficiency. Optional cored blades provide additional temperature control, which is essential for melting hot melt adhesives or protecting heat-sensitive ingredients.

Options include Stainless Steel 304/316 (with matt or mirror polish), Mild Steel (red oxide + epoxy paint), and special alloys/coatings (e.g., PTFE, hard chrome) for corrosion and abrasion resistance from fillers like silica or pigments. PTFE shaft seals ensure food-grade compatibility where needed.

Discharge methods include manual hand-wheel tilting, hydraulic automatic tilting, bottom discharge valves, and extrusion screw systems. These minimize waste, reduce operator effort, and enable efficient unloading of heavy, sticky adhesives.

Popular enhancements include vacuum systems (for bubble-free adhesives and de-aeration), liquid spray systems, variable frequency drives (VFD), overload protection, screw feeding, and explosion-proof designs. These support customization for specific adhesive processes.

It shortens processing time, improves product consistency and bonding performance, offers excellent scalability from R&D to full production, and provides durability for abrasive materials with minimal maintenance. The design ensures self-wiping action, minimal dead zones, and reliable operation for high-viscosity batches.

It is widely applied in Pharmaceutical, Nutraceutical, Herbal, Ayurvedic, Biotech, Cosmetic, and general Chemical industries for processing dense pastes, creams, ointments, rubber compounds, pigments, and other high-viscosity formulations requiring thorough homogenization.

It features high-grade stainless steel with smooth polished surfaces, minimal gaps between blades and trough (to prevent sticking), PTFE seals, and a hygienic design that supports GMP compliance. These elements make cleaning straightforward and suitable for regulated industries.
