200L Multi-Functional Vacuum Strong Power Dispersing Mixer QF-200-265L
In the manufacturing and R&D processes of modern fine chemicals, lithium-ion battery slurries, high-polymer adhesives, and advanced pharmaceutical materials, deep compounding and microscopic dispersion of high-viscosity, high-solid-content materials under absolute safety conditions remain critical to ultimate product quality.
As a premier global manufacturer of industrial agitation and fluid mixing systems, MAXWELL machine has channeled its deep flow-dynamics Research and Development Knowledge (RDK) into the QF-200-265L Multi-Functional Vacuum Strong Power Dispersing Mixer (Triple-Shaft Vacuum Disperser). Specifically engineered for pilot scaling and small-scale industrial production, this QF-200-265L model handles complex engineering conditions involving flammable or explosive volatile solv
ents. Equipped with a top-tier industrial explosion-proof system, it stands as a flagship workhorse for processing high-viscosity materials.
Working Principle
The MAXWELL Strong Power Mixer operates on an advanced mixing mechanism that combines "independent multi-shaft linkage, macro-convective circulation, and microscopic high-shear dispersion."
Within the fully sealed vacuum vessel, three mixing shafts cooperate under independent drive systems to generate mutually complementary flow fields:
Low-Speed Anchor-Type Wall-Scraping System (Macro Flow Propulsion):
Driven by a powerful 7.5KW motor operating at 76 RPM, this assembly rotates in close proximity to the vessel wall and bottom. It delivers substantial axial and radial torque, forcing the bulk of high-viscosity fluid into a three-dimensional turnover and pushing materials into the high-shear zones. Its specialized PTFE wall-scrapers continuously sweep the interior shell to ensure optimal heat transfer and completely eliminate dead zones—even at ultra-high viscosities exceeding 300,000 cps.
Dual High-Speed Dispersing Systems
Powered by an 11KW high-output motor operating at 1450 RPM, the twin high-speed shafts feature saw-tooth dispersing discs that generate immense linear tip speeds. As components pass through the periphery of these discs, they experience intense local shear, compression, tearing, and laminar friction. This not only breaches fluid surface tension instantly but also shatters microscopic agglomerates formed right after powder charging, delivering uniform microscopic dispersion down to the nano/micron scale.
Core Features & Superior Technical Highlights
MAXWELL Independent Triple-Shaft Drive: Breaks the processing limitations of traditional single-shaft or co-axial mixers. The 7.5KW low-speed torque governs the macro-fluid circulation, while the 11KW high-speed assemblies execute microscopic shattering. This dual-action design seamlessly resolves rheological processing bottlenecks associated with shear-thinning or shear-thickening (dilatant) non-Newtonian fluids.
Top-Tier Explosion-Proof Integrity (ATEX/GB Standards): All main motors, control enclosures, local operator panels, safety light curtains, and instrumentation sensors carry rigorous explosion-proof certifications (such as Ex d IIB T4 Gb rating), rendering the system completely safe for production zones handling NMP, toluene, xylene, absolute ethanol, or other flammable volatile solvents.
Heavy-Duty Shock-Absorbing Rigid Frame (Anti-Fatigue Build):
Weighing 2500 KG, the robust chassis consists of heavy-duty, thick-walled carbon steel internally, wrapped in premium stainless steel cladding. This scientific gravity-matrix distribution completely absorbs the intense dynamic load and unbalanced moments produced at 1450 RPM, guaranteeing resonance-free, low-noise operation while vastly extending the service life of bearings and mechanical seals.
Smart Closed-Loop Temperature Control Jacket (RDK Process Protection):
The mixing vessel integrates a dual-layer pressure jacket compatible with chilled water, thermal oil, or steam. Paired with a PT100 temperature sensor embedded inside the mixing blade, it establishes closed-loop thermal regulation with the main PLC controller, protecting temperature-sensitive formulas from thermal degradation or premature gelation caused by frictional heat.
Optional Configurations & Custom Systems
To satisfy the most rigorous process criteria across varying industries, MAXWELL provides modular upgrades for the QF-200-265L platform:
Material Upgrades: The standard product-contact metallurgy is SUS304. This can be customized to SUS316L (for highly corrosive chemical or pharmaceutical materials) or surface-coated with Tungsten Carbide / Teflon anti-wear linings (for high-hardness lithium battery cathode materials to achieve zero iron contamination).
Automated Feeding Modules: The vessel cover can be provisioned with quick-connect liquid ports, vacuum negative-pressure ports for powder induction, and load cells integrated beneath the chassis to interface with centralized ERP systems for automated batching and weighing.
Auxiliary Discharge Systems: Can be paired with a matching 200L Hydraulic Extruder (Discharging Press). For non-flowing pastes, the high-pressure press plate forces 100% of the material out through the bottom valve, completely eliminating material waste.
Control System Upgrades: Step up from standard explosion-proof push-button controls to a premium Siemens PLC + Explosion-proof Human-Machine Interface (HMI), allowing multi-group recipe storage, programmable multi-stage speed profiles, and comprehensive historical temperature data logging.

Quality Control (QC) & Maintenance Guide
To guarantee that this 2.5-ton heavy-duty system runs continuously and stably 24/7 in your facility, MAXWELL implements benchmark-level standards for factory acceptance and field maintenance:
Rigorous Pre-Shipment QC Inspections
Dynamic Balance Testing: The 1450 RPM high-speed shafts must pass high-precision dynamic balancing prior to leaving the plant, ensuring shaft runout stays within ultra-low, safe tolerance margins.
Jacket & Vessel Leakage Testing: The vessel jacket undergoes strict water pressure and pneumatic pressure-holding tests, maintained for several hours with zero pressure drop to guarantee exceptional seal integrity under industrial extremes.
Safety Interlock & HazLoc Electrical Verification: Simulates power outages, motor overloads, head-lift misalignments, and open-vessel statuses to ensure that the safety interlock and emergency stop mechanisms trigger 100% of the time.
Proactive Preventive Maintenance
Weekly Inspection: Evaluate the wear profile of the low-speed shaft's PTFE scrapers. If scraping efficiency drops or severe wear is observed, adjust the spring tension stroke or replace the scraper blades promptly.
Lubrication Management: Gearboxes and high-speed bearing housings must be regularly replenished with high-temperature, explosion-proof grease, and gear oil changes must be executed strictly following the operational hours outlined in the manual.
Mechanical Seal Care: After running batches containing highly volatile solvents, check the level and clarity of the mechanical seal cooling fluid immediately. Running the mechanical seal dry without coolant is strictly prohibited to maintain long-term vacuum sealing performance.
