Product Description

The vacuum disperser stands as a masterclass in industrial engineering, designed to transform the most challenging liquid-solid wet processing tasks into a seamless operation. When you approach the machine, the robust, mirror-polished stainless steel exterior immediately communicates its premium craftsmanship and resilience against harsh chemical environments. As the single-arm hydraulic system smoothly lowers the heavy-duty mixing shafts into the vessel, the equipment operates with a reassuringly steady, low-decibel hum, even when tackling highly viscous pastes or volatile solvents. This sophisticated machinery operates within a strictly controlled vacuum environment, meticulously stripping away trapped air and preventing solvent evaporation. By eliminating these microscopic voids, the resulting compounds achieve a flawless, glass-like smoothness and structural density that elevates the final product's quality. Whether processing heavy-duty marine coatings, delicate cosmetic ointments, or advanced magnetic materials, the intense shear forces break down stubborn agglomerates, delivering a remarkably consistent, ultra-fine dispersion. The intuitive design ensures that operators can maintain strict control over the entire cycle, resulting in a pristine, bubble-free yield that meets the most exacting industrial standards.

Product Specifications

• Pin-Hole Elimination: Guarantees a flawless, smooth finish in applied coatings and adhesives by preventing off-gassing and pin-hole defects during the curing process.

• Solvent Retention: Effectively suppresses the boiling point of volatile components, keeping essential solvents integrated within the mixture rather than lost to the atmosphere.

Dispersion & Mixing Efficiency

Time is a critical metric in industrial processing. This machine leverages a synchronized, multi-axis kinetic approach to drastically reduce batch times while achieving microscopic uniformity, ensuring your production line operates at peak efficiency.

• Dual-Axis Synergy: Combines the relentless shearing force of the inner shaft (up to 1500 rpm) with the steady, folding action of the middle shaft (up to 200 rpm) for comprehensive material turnover.

• Micro-Level Homogenization: Generates intense mechanical and hydraulic shear, tearing apart stubborn powder clusters to achieve a consistent 1-2 μm fineness.

• Wall-Scraping Precision: Engineered with precise tolerances, the scraping mechanism clears the inner walls continuously, forcing heavy pastes back into the high-shear zone.

• Viscosity Versatility: Seamlessly adapts to fluctuating viscosities throughout the processing cycle, maintaining optimal flow dynamics without overloading the drive system.

Material Durability & Cleanliness

Cross-contamination and equipment degradation are unacceptable risks in high-stakes manufacturing. We construct our dispersers using premium-grade alloys and finishing techniques to meet the strictest hygiene and anti-corrosion standards.

• Premium Alloy Construction: Manufactured from heavy-duty SUS304 or SUS316L stainless steel, offering exceptional resistance to aggressive acids, alkalis, and abrasive particulates.

• Mirror-Polished Surfaces: The interior vessel and mixing implements feature a flawless, mirror-like finish, preventing sticky resins or pigments from adhering to the metal.

• GMP & Battery Grade Compliance: Perfectly suited for pharmaceutical ointments or lithium battery slurries, where preventing metal ion pollution and ensuring absolute sterility are paramount.

• Rapid Washdown: The smooth, crevice-free design allows for aggressive clean-in-place procedures, drastically reducing downtime between color or formulation changes.

Hydraulic Lifting & Discharge System

Handling heavy, viscous pastes manually is both dangerous and inefficient. Our advanced hydraulic architecture automates the most labor-intensive aspects of the mixing process, ensuring smooth transitions and maximizing material recovery.

• Vibration-Free Elevation: The single-arm hydraulic shaft lifting system operates with fluid precision, raising and lowering the heavy agitation assembly without jarring or mechanical stress.

• Effortless Vessel Swapping: Designed to accommodate quick-release clamping, allowing operators to seamlessly roll out a finished batch and position a new vessel in minutes.

• High-Viscosity Extrusion: Can be paired with an optional hydraulic discharge press, applying uniform downward pressure to force out thick, non-flowing pastes with nearly zero residual waste.

• Operator Ergonomics: Minimizes manual lifting and scraping, significantly reducing the risk of workplace injuries and operator fatigue during demanding production shifts.

Temperature Control System

High-speed kinetic dispersion naturally generates substantial thermal energy, which can be detrimental to sensitive compounds. Our integrated thermal management infrastructure ensures your materials remain exactly within their required temperature parameters.

• Jacketed Vessel Design: Features a highly efficient double-wall jacket, allowing for the continuous circulation of chilled water or thermal oil depending on the process requirements.

• Thermal Degradation Prevention: Instantly dissipates excess heat generated by the 1500 rpm shear blades, protecting heat-sensitive adhesives and battery binders from premature cross-linking.

• Uniform Heat Distribution: The slow-moving outer agitator continuously moves material away from the jacketed walls, preventing localized hot or cold spots within the batch.

• Viscosity Manipulation: Allows operators to precisely warm thick resins to lower their viscosity prior to high-speed dispersion, optimizing the energy efficiency of the motor.

Safety, Explosion-Proof & Sealing

Processing highly volatile chemicals demands uncompromising safety protocols. We have engineered this disperser with robust containment and ignition-prevention technologies to protect your facility and personnel.

FAQ

Find answers to the most common technical inquiries regarding our dispersion technology and discover how it can be integrated into your production line.

How does the vacuum system improve the quality of high-viscosity resins?

By operating at a limit vacuum of ≤ -0.098 MPa, the system forcefully extracts entrapped air and moisture that are folded into the resin during the initial wetting phase. This prevents microscopic voids, ensuring a dense, structurally sound, and visually flawless final product.

Can this equipment handle materials that are highly sensitive to temperature fluctuations?

Absolutely. The disperser features a precision-engineered jacketed vessel that allows for the circulation of cooling water or thermal oil. Combined with the continuous folding action of the slow-speed agitator, it rapidly dissipates the kinetic heat generated by the high-shear blades.

What maintenance is required for the double-face mechanical seals?

Our double-face mechanical seals are designed for extended longevity with minimal intervention. They require periodic inspection of the barrier fluid levels and pressure. Because of their robust design, they significantly outlast standard packing seals, especially when processing abrasive pigments.

Is it possible to use multiple vessels with a single hydraulic lifting head?

Yes, this is one of the most efficient ways to utilize the equipment. The single-arm hydraulic lift allows you to raise the agitators, roll away the finished batch for discharge, and immediately roll in a newly prepped vessel, increasing your overall throughput substantially.

How does the machine ensure no unmixed materials are left on the vessel walls?

The middle stirring shaft is equipped with specialized wall-scraping blades. As the shaft rotates at 0-200 rpm, these scrapers physically wipe the interior walls, continuously pushing stagnant, heavy materials back into the central high-speed dispersion zone to guarantee a perfectly homogenous mixture.
