A Double Shaft Adhesive Mixer Agitator is a powerful industrial mixing machine engineered specifically for handling high-viscosity materials. Designed to process thick, challenging substances like adhesives, sealants, pastes, gels, silicones, epoxies, and other heavy formulations, this advanced equipment delivers superior mixing performance where single-shaft mixers often fall short.
In industries where product consistency and uniformity are critical, the double shaft adhesive mixer agitator stands out as a top choice. It features two independently driven shafts equipped with different types of agitators — typically combining high-speed dispersers, low-speed anchors, helical ribbons, or scrapers. These shafts rotate at varying speeds and directions, working in perfect synchronization to create efficient mixing, excellent dispersion, and complete material turnover even in batches reaching several hundred thousand to over a million centipoise (cps).
This combination allows the mixer to handle shear-thinning materials effectively—breaking down agglomerates while ensuring uniform blending without dead zones.
The machine uses two independently driven shafts fitted with different agitators (typically a high-speed disperser combined with a low-speed anchor, helical ribbon, or scraper). The shafts rotate at varying speeds and directions in synchronization, ensuring efficient mixing, excellent dispersion, complete batch turnover, and elimination of dead zones even at viscosities of several hundred thousand to over a million centipoise (cps).
It is designed for high-viscosity adhesives, sealants, pastes, and formulations up to several hundred thousand centipoises (or higher for shear-thinning materials). The dual-action system continues to provide thorough mixing as viscosity increases during the batch.
Salient features include independently controlled shafts for process flexibility, PTFE/Teflon scrapers for continuous wall cleaning and improved heat transfer, jacketed vessels for heating or cooling, optional vacuum capability to remove air and produce bubble-free products, change-can or fixed vessel options with hydraulic/pneumatic lift, stainless steel (304 or 316) construction with polished surfaces, and robust safety interlocks with variable frequency drives.
The low-speed shaft is typically equipped with an anchor (or helical/scraper) agitator that provides bulk movement, wall scraping, heat-transfer improvement, and material feed to the center. The high-speed shaft usually carries a saw-tooth or open-disc disperser blade that creates intense turbulence and a vortex for rapid powder wetting, deagglomeration, and fine dispersion. Shafts may be concentric or offset, with adjustable speeds via inverters.
It is suitable for the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries—anywhere high-viscosity adhesives, sealants, coatings, epoxies, silicones, hot melts, or high-solids formulations require consistent, uniform mixing.
Key benefits include the ability to handle viscosities far beyond standard dispersers, faster processing with better homogeneity, reduced air incorporation (especially with vacuum options), scalability from lab sizes (1–5 gallons) to production (up to 1500+ gallons), and customizability (e.g., explosion-proof motors).
Yes. The jacketed vessel design allows precise heating or cooling during processing. Vacuum capability is available to remove air entrainment and produce bubble-free, high-quality products.
The low-speed anchor (or helical) agitator continuously turns over the entire batch, scrapes the vessel walls to prevent buildup, improves heat transfer, and continuously feeds material toward the high-speed disperser for efficient dual-action mixing.
Yes. It offers change-can or fixed vessel options with hydraulic or pneumatic lift systems, enabling easy cleaning and convenient multi-batch operation while maintaining hygiene through polished stainless-steel surfaces.
