500L Horizontal Kneader with Bottom Discharge

It is suitable for silicone rubber, sealants, structural adhesives, hot-melt adhesives, rubber compounds, inks, pigments, carbon materials, battery slurries, paste cosmetics, and polymer composites. The final configuration should be confirmed based on material viscosity, temperature, vacuum requirements, and discharge method to determine the appropriate kneader solution.

Hydraulic tilting discharge has a simple structure and is easy to maintain, making it suitable for multi-product, small-batch, or frequent-cleaning scenarios. Bottom discharge is better for continuous production and can be paired with screw extrusion for controlled unloading and easier integration with downstream equipment. For highly automated lines, a bottom-discharge kneader is usually more suitable.

To ensure proper kneading performance and stable motor load, the filling coefficient is generally recommended between 0.55 and 0.70. This means the effective loading per batch for a 500L kneader is typically around 275L-350L, 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, steam heating, water cooling, SUS316L material, and screw extrusion bottom discharge. Please provide material viscosity, process temperature, vacuum requirements, and site power conditions to confirm the final kneader configuration.

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.
