1L Laboratory Planetary Vacuum Mixer with Cantilever Lifting Bucket for Lithium Battery Slurry Mixing

Product Overview

This 1L laboratory planetary vacuum mixer is designed for the controlled mixing and dispersion of powders and liquids used to produce uniform battery slurry. Its cantilever lifting bucket configuration supports practical vessel handling, while the integrated planetary mixing and high-speed dispersion functions address demanding laboratory preparation tasks. The working vessel is suitable for small-batch process development where repeatability, material compatibility, and close control of mixing conditions are essential.

The equipment is intended for slurry preparation across common battery chemistries, including lithium battery research, as well as related materials development. It is particularly suitable for high-viscosity processes up to 1,200,000 cP. Separate mixing and dispersion assemblies allow the operator to combine bulk homogenization with intensive particle deagglomeration in a compact laboratory platform.

A jacketed vessel supports heating or cooling through both the vessel wall and bottom. The 304 stainless steel material-contact construction, defined tool clearances, adjustable operating frequencies, and robust mechanical arrangement provide a practical foundation for demanding research and pilot-scale work. The external circulation system is customer-supplied, allowing process teams to integrate the equipment with their preferred temperature-control resources.

Key Features

• High-Viscosity Processing: Handles process conditions with viscosity up to 1,200,000 cP, making the equipment suitable for challenging battery slurry and other thick material formulations.

• Planetary Mixing and High-Speed Dispersion: A planetary mixing assembly operates alongside a separate toothed dispersion disc to combine bulk circulation with intensive dispersion of powders and liquids.

• Cantilever Lifting Bucket: The cantilever vessel arrangement supports manual handling of the mixing container, simplifying loading, unloading, inspection, and laboratory batch changeover.

• Jacketed Temperature Management: Single-layer jackets on the vessel wall and bottom can be used for heating or cooling, helping researchers manage temperature-sensitive formulations during mixing and dispersion.

• Controlled Tool Clearances: The mixing blade is positioned 3.5 ± 1 mm from the vessel wall and 2 ± 1 mm from the vessel bottom, supporting consistent material movement within the compact vessel.

• 304 Stainless Steel Contact Parts: The vessel contact area, mixing blade, and dispersion disc use 304 stainless steel for a durable and process-compatible material-contact surface.

• Wide Operating Range: Mixing frequency is adjustable from 5-50 Hz, while the mixing blade operates at 14-130 rpm. This supports parameter development across different slurry compositions and viscosities.

• Intensive Dispersion Capability: The dispersion assembly provides a speed range of 580-58,000 rpm and a line speed of 1.8-18 m/s, enabling high-shear laboratory dispersion work.

• Compact Small-Batch Capacity: A designed total volume of 2.1 L and effective volume of 0.7-1 L provide a practical scale for formulation screening, process optimization, and laboratory validation.

Applications

Technical Specifications

The vessel volume configuration is suited to laboratory batches rather than unrestricted production-scale processing. The designed total volume is 2.1 L, while the effective operating volume is 0.7-1 L. Maintaining the effective volume within the stated range helps preserve appropriate working space for powder incorporation, slurry movement, and dispersion.

The mixing system uses a single 83 mm variable-section spiral twisted blade with a 90° spiral line. Its planetary box speed is 5-40 rpm, and the blade speed is 14-130 rpm. These independently stated operating ranges provide useful flexibility when developing recipes with different flow characteristics. The specified wall and bottom clearances establish the intended mechanical relationship between the blade and the vessel.

The separate dispersion system uses one 60 mm toothed disc mounted on one dispersion shaft. Its 1.1 kW power rating and 580-58,000 rpm speed range support intensive laboratory dispersion studies. The stated line-speed range is 1.8-18 m/s. Together with the planetary mixing assembly, this configuration is intended for processes requiring both overall blending and localized high-speed dispersion.

Temperature control is provided through single-layer jackets on the vessel wall and bottom. The jacket connections are G3/8" and include quick-opening union fittings. The jacket pressure resistance is ≤0.4MPa. The circulation system is not included in the stated equipment configuration and must be supplied by the customer. For cooling applications, the reference conditions recommend an inlet water temperature of ≤8℃ and a cooling-water flow rate greater than 3.5L/min.

Why Choose This Product

• Built for Difficult Slurries: The stated viscosity capability of ≤1200000 cP gives research teams a defined solution for high-viscosity battery and materials formulations.

• Integrated Process Functions: Combining planetary mixing with high-speed toothed-disc dispersion provides broader process capability than a basic single-action laboratory mixer.

• Durable Material Selection: 304 stainless steel is specified for the product-contact vessel area, mixing blade, and dispersion disc, supporting long-term laboratory use and straightforward material compatibility planning.

• Temperature-Control Flexibility: Wall and bottom jackets allow the unit to be connected to a customer-selected cooling or heating circulation system according to process requirements.

• Practical Laboratory Scale: The 0.7-1 L effective volume supports formulation screening, parameter optimization, and repeatable small-batch development without committing to larger production equipment.
