1. Product Positioning & Core Working Principle

This equipment is an integrated small laboratory vacuum mixing and dispersing machine that combines planetary stirring, high-speed dispersion and vacuum defoaming functions. Driven by a planetary gear transmission structure, it achieves composite mixing motion: the stirring paddles revolve around the center of the mixing tank at a low speed, while the paddles and dispersion disc rotate independently. Equipped with a synchronous wall scraper, it enables full-range dead-angle-free mixing, suitable for small-batch experimental preparation of high-viscosity systems mixed with powder and solvent.

2. Main Structural Components 

1. Mixing Assembly with Four Paddles It comes with 2 groups of twisted frame mixing paddles,

 high-speed dispersion disc and 1 wall-fitting scraper. The gap between paddles and tank wall is extremely narrow. The scraper continuously scrapes off materials adhered to the tank wall during revolution to avoid material accumulation and uneven mixing.

2. Stainless Steel Mixing Tank Made of full stainless steel with interlayer water channel interfaces. It can be connected to a chiller or hot water bath for material temperature control. The total volume is 2.9L with an effective mixing volume of 2L, and the minimum stirring volume is 350ml, ideal for laboratory formula trial production. The tank is fitted with handles and can be lifted and separated for easy feeding, discharging and cleaning.

3. Vacuum System The sealed mixing chamber reaches a maximum vacuum degree of -0.095MPa with a pressure drop of less than 5KPa within 8 hours for stable vacuum holding. It can be connected to a centralized vacuum source or matched with an independent vacuum pump. Mixing and vacuum pumping proceed simultaneously to completely eliminate air bubbles in slurry and prevent material oxidation.

4. Intelligent Control Panel Equipped with a touch display, power start-stop buttons and emergency stop knob. The mixing time can be freely set from 0 to 9999 minutes. Revolution, mixing and dispersion speeds are adjustable separately, supporting segmented process programming. Electrical interlock is applied between vacuum and mixing operation to guarantee safe operation. 5. Machine Frame The whole machine adopts stainless steel frame with an electric control top cover, fitted with adjustable support feet at the bottom to occupy little floor space. A built-in cooling fan ensures heat dissipation. The overall dimension is 575mm×345mm×750mm, and the net weight is about 150kg.

3. Key Technical Parameters

Power supply is single-phase AC220V (AC110V customizable), 50/60Hz. The total power is 1600W, including 2350W for the vacuum pump. The maximum revolution speed is 47rpm, the maximum mixing paddle speed is 295rpm, and the top rotational speed of the dispersion disc reaches 4000rpm. It delivers stable vacuum performance with a maximum vacuum degree of -0.095MPa. The mixing tank has an inner diameter of 150mm and a height of 165mm with an interlayer temperature control structure. Recommended operating environment: ambient temperature 25±3°C, humidity 30~90RH, free of vibration and strong electromagnetic interference.

4. Core Product Advantages 

1. High Mixing Uniformity Low-speed twisted paddles conduct macro material turnover, while the high-speed dispersion disc provides strong shear force to break up powder agglomerates. The wall scraper cleans the tank wall synchronously. Superimposed multi-layer movement realizes even mixing of high-viscosity slurry within a short time.

2. Integrated Vacuum Defoaming Mixing is carried out in a fully sealed negative pressure environment, which eliminates bubbles in paste and electrode slurry, improving the compactness and performance consistency of finished products.

3. Specially Designed for Laboratory Use The compact body fits laboratory bench layout. The small-volume mixing tank reduces raw material waste during formula research trials. The liftable tank design simplifies feeding, discharging and cleaning operations.

4. Flexible Process Adaptability All parameters including rotation speed, mixing time and vacuum degree are adjustable. The interlayer temperature control supports heating or cooling to adapt to various materials with different viscosity and temperature sensitivity. 5. Stable and Durable Operation The anti-corrosion stainless steel chamber and precise transmission structure enable low-noise operation and stable performance under long-term continuous experimental conditions.

5. Applicable Industries & Material Scenarios 

It is mainly used for laboratory batching and mixing of various powder, solvent and high-viscosity paste materials: New energy industry: cathode and anode electrode slurry for lithium-ion batteries, composite materials for solid-state batteries; Optoelectronic materials: conductive slurry for solar energy, adhesive for optical tapes; Fine chemical industry: adhesives, conductive paste, ceramic slurry, sealant and polymer composite materials; New material research: various composite systems of powder and solvent, small-batch trial production of high-viscosity formulas.

6. Brief Operation Process 

First, feed powder and solvent raw materials into the stainless steel mixing tank and fix the tank in position on the equipment. Second, seal the chamber, set mixing duration as well as revolution and dispersion speeds, then turn on the vacuum system. Third, start the machine. The mixing paddles perform revolution and rotation together with high-speed shearing from the dispersion disc, while defoaming proceeds under negative pressure throughout the process. Fourth, the machine stops automatically once the process finishes. Release vacuum, lift and separate the tank, take out finished slurry and clean the tank and paddles.
