3000L Vertical Kneader

It is suitable for carbon fiber prepreg resin matrices, high-temperature sealants, structural adhesives, thermal conductive adhesives, specialty energetic materials, and high-solid polymer composites. The final kneader configuration should be confirmed based on material viscosity, filler ratio, temperature control range, and vacuum requirements.

To ensure proper kneading performance and stable motor load, the filling coefficient is generally recommended around 0.6-0.7. This means the effective loading per batch for a 3000L kneader is typically around 1800L-2100L, subject to the material’s specific gravity and viscosity.

Yes. It can be customized with a vacuum system, explosion-proof motor, PLC/HMI control, thermal oil heating, water cooling, SUS316L material, and special blade types. Please provide material viscosity, temperature range, vacuum requirements, and site power conditions to confirm the final kneader configuration.

The vertical structure uses gravity to assist discharge, has fewer bottom dead corners, and is easier to clean and change over. Planetary stirring with wall scrapers reduces build-up and dead corners, making it suitable for high-viscosity, high-cleanliness materials. Horizontal kneaders still have advantages for certain high-viscosity pastes and screw extrusion discharge. The kneader type should be selected based on the production process.

A kneader is a mixing machine for high-viscosity materials. Two Z-type (or sigma-type) blades rotate in opposite directions inside the vessel, producing shear, folding and squeezing on the material for uniform kneading. It is widely used for silicone sealant, hot-melt adhesive, butyl rubber and battery slurry.

Vertical kneaders have a vertical vessel with blades entering from above - compact, space-saving, suitable for small-medium batches and frequent changeover. Horizontal kneaders have a horizontal vessel with larger batch capacity, suitable for medium-large production. The choice depends on batch size, workshop space and discharge method.

Kneaders handle pasty materials from 10,000 cP up to several million cP - the range that dispersers and mixers cannot cover. The upper limit depends on blade type, motor configuration and material properties.

The three cover different viscosity ranges. High-speed dispersers handle low-to-medium viscosity slurries below 10,000 cP through high-speed shear; planetary mixers use revolution plus rotation for pastes from tens of thousands to hundreds of thousands cP; kneaders are dedicated to materials above 100,000 cP, including semi-dry compounds, using folding and squeezing action - a common choice for sealants, hot-melt adhesives and battery slurry.
