100L Planetary Dispersion Vacuum Mixer with Cantilever Lifting Bucket for Battery Slurry

Product Overview

This 100L-class planetary dispersion mixer combines intensive planetary agitation with high-speed dispersion for preparing homogeneous battery slurries from powders and liquids. The equipment is designed for demanding, high-viscosity processes and supports effective mixing across an operating viscosity range of up to 1,200,000 cP. Its dual mixing and dual-shaft dispersing arrangement promotes thorough material circulation, wetting, and deagglomeration within the working vessel.

The system is suited to common battery material formulations, including processes that require consistent blending of active powders, conductive additives, binders, and liquid media. It is relevant to battery research, pilot production, advanced materials development, powder processing, and other laboratory or industrial applications where repeatable slurry quality is essential.

Robust wetted construction, close blade clearances, jacketed vessel temperature management, and controlled bottom discharge support reliable operation under demanding conditions. Mobile caster-based movement also helps users reposition the equipment within a production or research area when workflow requirements change.

Key Features

• High-Viscosity Processing Capability: The equipment is designed for applications with viscosity up to 1,200,000 cP, making it suitable for thick battery slurries and other difficult-to-process formulations.

• Planetary Agitation and High-Speed Dispersion: Two planetary mixing blades work together with two dispersing shafts and four dispersing discs. This combination supports bulk material turnover, powder wetting, particle breakup, and uniform slurry formation.

• Adjustable Mixing and Dispersion Speeds: Mixing blade speed is adjustable from 5 to 52 rpm, while dispersing speed ranges from 275 to 3,575 rpm. Separate operating frequency ranges allow users to adapt the process to different formulation and shear requirements.

• Close-Clearance Mixing Geometry: The mixing blades maintain 7 ± 1 mm blade-to-blade clearance, 5 ± 1 mm blade-to-wall clearance, and 4 ± 1 mm blade-to-bottom clearance. These controlled gaps help improve material movement and reduce stagnant zones.

• Jacketed Temperature Management: Single-layer jackets on both the vessel wall and vessel bottom can be used for heating or cooling. The arrangement supports thermal control during mixing and dispersing, subject to the customer-supplied circulation system.

• Durable Stainless Steel Wetted Construction: Material-contact components, mixing blades, and dispersing discs are manufactured from 304 stainless steel. This provides a robust process-contact surface for repeated battery material preparation.

• High-Throughput Dispersion Configuration: Four 125 mm serrated dispersing discs provide multiple high-shear interfaces. With a dispersing line speed of 1.8 to 23 m/s, the equipment is configured for intensive dispersion work.

• Controlled Bottom Discharge: A bottom-mounted G1-1/2 inch three-piece discharge ball valve is supplied with a 2 inch standard ISO quick-connect clamp fitting. This supports organized transfer from the vessel to downstream equipment or containers.

• Mobile Equipment Layout: The vessel assembly uses a caster-based mobile design, allowing practical movement during installation, maintenance, or production-line reconfiguration.

Applications

Technical Specifications

The vessel capacity is configured to support a practical 45 to 100 L effective working range within a 140 L designed total volume. This operating range gives process engineers room to accommodate formulation characteristics, powder loading behavior, and batch handling requirements without relying on a single fixed fill level.

The mixing section uses two variable-cross-section helical twisted blades with a 90° helix line. Their controlled clearances are particularly important for viscous materials because they help maintain material movement near the vessel wall and bottom. The planetary box rotates at 3 to 30 rpm, while the mixing blades operate at 5 to 52 rpm, giving users separate mechanical variables for balancing turnover and shear.

The dispersion section provides a distinct high-speed processing function. Two shafts carry four serrated discs, each measuring 125 mm in diameter. The specified dispersion speed of 275 to 3,575 rpm and line speed of 1.8 to 23 m/s provide a broad operating window for particle wetting and agglomerate reduction. The separate 5 to 65 Hz working-frequency range supports process adjustment according to material response.

Temperature management is integrated into the lower vessel assembly through wall and bottom single-layer jackets. These jackets can be used for heating or cooling, while the circulation system is supplied by the customer. For the specified cooling arrangement, the recommended jacket inlet water temperature is no higher than 8°C and the cooling-water flow rate is greater than 40 L/min. The jacket pressure must remain at or below 0.4 MPa.

The bottom discharge arrangement is designed for organized material transfer. The G1-1/2 inch three-piece ball valve and 2 inch standard ISO quick-connect clamp fitting provide a defined outlet interface for collection vessels, transfer lines, or downstream processing equipment. The 304 stainless steel material-contact construction supports a durable and consistent process environment.

Why Choose This Product
