Longjun
Longjun’s Dual Drive Twin Shaft Mixer is a specialized heavy-duty mixing solution, purpose-built for industrial manufacturers and commercial production facilities processing high-viscosity and high-solid-content materials. Also known as concentric twin shaft mixer for viscous liquid, this equipment integrates high-speed dispersion and low-speed wall-scraping mixing functions into a single system, with two sets of agitators mounted on the same central axis to eliminate mixing dead spots. The standard 500L model can be fully customized, with optional vacuum sealing, explosion-proof design, electric heating and thermal oil heating systems, adapting to strict industrial production standards. This high speed dispersing twin shaft mixer delivers uniform, bubble-free and consistent mixing results, making it the gold standard for high-viscosity material processing across multiple industries.
The Dual Drive Twin Shaft Mixer operates on an innovative dual-power high-low speed synergistic design, delivering unmatched mixing performance that single-shaft equipment cannot match. The high-efficiency toothed dispersing disc runs at high speed, driving the material to form a circular flow pattern, generating a strong vortex, and creating intense shear impact and friction between material particles to achieve rapid dispersion, dissolution and uniform blending of solid-liquid components. Simultaneously, the low-speed frame-type agitator with movable wall-scraping blades continuously pushes materials adhering to the tank wall back into the high-shear working zone of the disperser, eliminating dead corners in the mixing tank. This dual-action design ensures no color difference in the final product, improves mixing uniformity and product transparency, and supports vacuum pressure operation when fitted with precision mechanical seals for sensitive production processes.

The coaxial design of high-speed dispersion and low-speed mixing achieves full coverage of the mixing tank, eliminating dead spots and ensuring 100% of the material is evenly processed, with mixing efficiency 2-3 times higher than traditional single-shaft mixers.
Supports non-standard customization including explosion-proof, sealed vacuum, heating and cooling systems, with multiple working heads available for combination, adapting to different process requirements from coating production to pharmaceutical formulation.
Equipped with a hydraulic lifting system for smooth and stable operation, frequency converter speed regulation for precise control of mixing speed, and a wall-scraping design that ensures no material adheres to the tank wall, reducing material waste and cleaning difficulty.
This wall-scraping dual shaft mixer is widely used in multiple industrial sectors:
Coating & Ink Industry: Automotive paint, furniture paint, industrial paint, water-based and oil-based ink production.
Adhesive & Chemical Industry: Sealants, epoxy resins, pesticides, ceramic slurries, battery paste processing.
Daily Chemical & Pharmaceutical Industry: Toothpaste, cosmetics, ointments, medical gels, nutrient solution production.
New Energy Industry: Lithium battery electrode slurries, electronic paste mixing and dispersion.
Fix the equipment on a horizontal foundation, calibrate the coaxiality of the transmission shaft, connect the hydraulic system and electrical control cabinet correctly, and ensure reliable grounding of the equipment to meet electrical safety standards.
Check the tightness of fasteners and the integrity of sealing components before operation, conduct no-load test run to confirm no abnormal noise or vibration, and feed materials gradually after the equipment runs stably, avoiding overfilling the tank.
Regularly check the oil level of the hydraulic system and replace the hydraulic oil according to the usage cycle. Check the wear of the wall-scraping blades and replace them in time to ensure the scraping effect. Clean the mixing tank and sealing components thoroughly after each production run to avoid cross-contamination between batches.
Yes. This equipment is specially engineered for high-viscosity materials, with the dual-axis synergistic design able to process thick pastes and slurries with viscosities up to millions of centipoise, eliminating dead spots and ensuring full uniformity of the final product.
