200L Stainless Steel Vacuum Electric Heating Vertical Kneader

The standard electric heating power of this kneader is typically between 18kW and 24kW. Under full load, it takes about 20minutes to heat from ambient temperature to 150℃ (depending on the specific heat capacity of the material). Temperature control is precise and no external boiler is required.

If your material is standard silicone sealant or non-highly corrosive chemicals, a SUS304 stainless steel kneader will suffice. However, for pharmaceuticals, food, or acidic/alkaline corrosive materials, SUS316L is highly recommended due to its superior corrosion resistance and anti-contamination capabilities.

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.
