2L Laboratory Planetary Vacuum Mixer Cantilever Lifting Bucket

Product Overview

This 2L laboratory planetary mixer is designed for blending and dispersing powders and liquids used in common battery formulations. Its dual-action planetary agitation and high-speed toothed dispersing system help produce uniform slurry while handling demanding high-viscosity processes. The cantilever lifting bucket configuration supports practical vessel access during loading, inspection, cleaning, and material handling.

The equipment is well suited to battery R&D, electrode slurry preparation, advanced materials development, powder processing, ceramics, and academic laboratory work. It accommodates processing viscosities up to 1,200,000 cP, with an effective working volume of 1.2L to 2L. Heating and cooling can be applied through the vessel wall and bottom jackets when connected to a customer-supplied circulation system.

Built around 304 stainless steel material-contact components, close-running clearances, and independently adjustable mixing and dispersion speeds, this unit supports repeatable laboratory-scale development. Its compact vessel and manually movable design make it appropriate for controlled batch processing where consistency, cleanability, and process flexibility are essential.

Key Features

• High-Viscosity Processing: The system is suitable for process conditions with viscosity up to 1,200,000 cP, supporting demanding battery slurry and advanced material formulations that require strong mechanical action.

• Dual Mixing and Dispersion: Two planetary mixing blades work together with one independent toothed dispersion disc. This combination promotes bulk circulation, powder wetting, agglomerate breakup, and uniform material distribution within one vessel.

• Adjustable Planetary Agitation: Mixing frequency is adjustable from 5 to 50 Hz, with an agitator speed range of 8 to 76 rpm. Operators can adapt the mechanical action to different formulations and processing stages.

• High-Speed Dispersion: The dispersion system operates from 450 to 4,450 rpm and provides a line-speed range of 1.3 to 13 m/s. This supports efficient deagglomeration and fine distribution of solid components in viscous liquid systems.

• Controlled Thermal Conditioning: Single-layer jackets on both the vessel wall and vessel bottom can be used for heating or cooling. This helps manage temperature-sensitive formulations and maintain more stable processing conditions.

• Durable 304 Stainless Steel Contact Parts: The vessel contact surfaces, mixing blades, and dispersion disc are manufactured from 304 stainless steel, providing a robust foundation for laboratory production and repeated material development cycles.

• Close-Running Mixing Geometry: The mixing blades maintain a 3+1 mm clearance from the vessel wall and a 2-3 mm clearance from the vessel bottom. The blade-to-blade pitch is specified at 6±1 mm for controlled mechanical interaction.

• Compact Laboratory Vessel: The 3.8L designed total volume and 1.2L-2L effective volume provide a practical scale for formulation screening, process optimization, and small-batch electrode material preparation.

• Manual Vessel Handling: The vessel is not equipped with casters and is intended for manual movement. This arrangement provides a straightforward laboratory setup for users who prioritize a compact footprint and fixed-position operation.

Applications

Technical Specifications

The vessel geometry is configured around a 180mm internal diameter and 150mm internal depth, giving users a defined working area for laboratory-scale formulation work. The effective volume of 1.2L-2L allows operators to select a batch size appropriate to the material system, experimental design, and required headspace. The designed total volume is 3.8L, providing additional vessel capacity beyond the stated working range.

The mixing assembly uses two 94mm variable-section spiral twisted blades with a 90° spiral line. Their specified clearances help maintain active material movement near the vessel wall and bottom while limiting unnecessary dead zones. The 6±1 mm blade pitch provides a defined relationship between the two mixing elements and the material being processed. These details are important when users compare laboratory mixers for repeatability and scale-up studies.

The independent dispersion assembly adds a different type of mechanical action. A 60mm toothed disc mounted on one dispersion shaft rotates from 450 to 4,450 rpm. Its specified line speed of 1.3-13 m/s provides a useful operating window for wetting, deagglomeration, and dispersion trials. The separate 1.1 kW dispersion drive complements the 0.75 kW mixing drive, allowing the system to combine bulk movement with localized high-shear action.

Thermal control is provided through two single-layer jacket sections. The vessel wall jacket and vessel bottom jacket can each be used for cooling or heating, subject to the requirements of the connected circulation equipment. The jacket connection is G3/8" and includes a quick-opening union coupling. Jacket pressure resistance is specified at ≤0.4 MPa. The circulation system is customer supplied, with recommended jacket inlet water temperature of ≤8℃ and cooling-water flow rate of ＞3.5 L/min.

When integrating an external temperature-control system, users should confirm connector compatibility, circulation capacity, pressure limits, and the thermal requirements of the formulation. Proper utility planning helps maintain stable processing conditions and supports repeatable comparisons between batches. Because temperature behavior can influence viscosity, dispersion efficiency, and slurry uniformity, the jacket arrangement is particularly useful during process development.

The unit is designed for an ambient temperature range of -10~+120°C. The vessel has no discharge buckle, so material removal should be planned around the stated vessel configuration and the user’s laboratory handling procedure. The equipment has no casters and is intended for manual handling. Buyers should therefore evaluate bench layout, access clearance, lifting practices, and the desired permanent operating position before installation.

The contact materials are specified as 304ss for the vessel and 304 ss or 304 stainless steel for the mixing and dispersion components. This material selection offers a durable, practical contact surface for repeated laboratory processing across battery, ceramic, powder, and composite material applications. Users should still verify chemical compatibility between the formulation and all wetted materials before ordering, especially when processing aggressive solvents or reactive additives.

For procurement teams, the key selection criteria are effective batch volume, maximum supported viscosity, speed range, drive power, thermal-control requirements, and vessel-handling method. This configuration is especially appropriate where a compact laboratory platform must provide both controlled planetary mixing and high-speed dispersion. The available adjustment ranges also support formulation screening, allowing researchers to compare mechanical conditions without changing the core equipment platform.
