1000L Horizontal Vacuum Kneader (Bottom Discharge)
Efficient dispersion, vacuum degassing, and zero-residue bottom discharge—the 1000L Horizontal Kneader, the ideal kneader solution for high-viscosity materials.
This 1000L Horizontal Vacuum Kneader is a core equipment for processing high-viscosity and high-elasticity materials. Featuring unique Z-type or Sigma-type blades and a powerful vacuum system, it performs kneading, mixing, reacting, and degassing in a sealed environment. The specially designed bottom discharge structure (tilting tank or hydraulic ball valve)彻底 solves the pain points of difficult discharge and high residue in traditional kneaders. It is widely used in the production of silicone sealants, organic silicon, rubber, and battery slurries, serving as a powerful kneader to enhance productivity and quality.

How it Works
The kneader operates via two Z-type (or Sigma-type) blades rotating at different speeds in opposite directions, exerting intense shear, compression, and folding forces on the material. Under vacuum conditions, the material constantly tumbles and mixes within the horizontal U-shaped trough, achieving high uniformity while effectively removing volatiles and air bubbles. Upon completion, the hydraulic system tilts the cylinder or opens the bottom valve, enabling rapid and clean discharge.
Features at a Glance
Strong Kneading and Dispersion
Features optimized Z-type/Sigma-type blades with a speed ratio typically of 1:1.5 or 1:2, ensuring the kneader delivers superior shear force and dispersion when processing high-viscosity silicone sealants.
High-Efficiency Vacuum Degassing System
Equipped with high-performance vacuum pump interfaces and sealing structures, this horizontal kneader operates at a high vacuum degree of -0.098Mpa, effectively removing air bubbles and moisture to ensure product density.
Convenient Bottom Discharge Design
Unlike traditional manual digging, this Kneader supports hydraulic tilting or bottom ball valve discharge, significantly shortening discharge time, reducing manual intervention, and enabling easy unloading even with a 1000L large capacity.
Durable Construction and Easy Cleaning
Parts in contact with materials are made of high-quality stainless steel (e.g., 304/316L) with precision-polished inner walls. As a professional chemical Kneader, it is not only corrosion-resistant but also easy to clean, preventing cross-contamination.

Frequently Asked Questions
This horizontal kneader is designed for high-viscosity materials, specifically suitable for materials with viscosity between 10,00000 and 2,000,0000 cps, such as high-viscosity silicone sealants and butyl rubber.
Our Kneader uses advanced mechanical seals or packing seals combined with a vacuum system to effectively prevent powder dusting and air ingress, ensuring the kneading process takes place in a completely sealed vacuum environment.
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.
