Prepared from Yushun’s 2026 product knowledge base. Model data is preliminary selection guidance. Technical translations and final configurations require engineering review; flow and capacity figures are not performance guarantees for every material.
Choose Your Capacity Range
The 2–100 L single-arm and 150–1000 L gantry-style ranges are presented separately, each with its own equipment rendering. The series main image shows the gantry-style form, and the reference tables below cover the full 2–1000 L range. The 5100 L unit is a customer-specific custom build, not a standard model. Final frame style and configuration require project confirmation.
2–100 L
Vertical Planetary Kneader (2–100 L)
Single-arm vertical planetary kneading for small and pilot batches. NHJ-02 through NHJ-100 use this frame. Confirm the formulation, vacuum and temperature-control requirements, and discharge method before fixing the configuration.
Request Specifications & Quote150–1000 L
Vertical Planetary Kneader (150–1000 L)
Gantry-style vertical planetary kneading for production batches; standard models above 100 L start at 150 L. Confirm torque demand, discharge, vessel handling and installation envelope before sizing. Larger units are evaluated per project.

How it works
Planetary blade motion mixes and kneads viscous or elastic materials. Two- or three-blade arrangements, vacuum, and thermal control are configured for the formulation and production sequence.
How to choose a kneading system
Define viscosity, elasticity, solids content, batch size, temperature limits, vacuum requirements, and the expected discharge behavior. Standard table values are preliminary references. The listed vacuum figure requires confirmation of pressure reference and test conditions in the final specification.
Kneader vs. planetary mixer
Compare the required kneading action and torque with the dispersion and mixing needs of the formulation. See the double planetary mixer for another high-viscosity processing option. Discuss your process before selecting a custom capacity.

Technical questions
Frequently Asked Questions
Does the standard table define the largest unit Yushun can manufacture?
No. The table covers standard NHJ models from 2 to 1000 L. Yushun has manufactured a 5100 L custom unit for a customer. Larger projects require a separate engineering evaluation; no additional standard model is implied.
Is the equipment suitable for dry and wet processes?
The configuration can support solvent-free dry mixing or high-viscosity wet mixing, depending on the formulation and process.
Can a vertical kneader use an eccentric arrangement?
Yes. Vertical or horizontal describes the equipment orientation, while eccentric describes the mixing or shaft arrangement. They are not mutually exclusive classifications.
Which discharge methods are available?
Hydraulic tank tilting and ball-valve discharge can be evaluated. Selection depends on flow behavior, viscosity, batch size, residue limits, and cleaning requirements.
How does a kneader differ from a double planetary mixer?
A kneader is evaluated for more elastic materials and processes with demanding kneading and torque requirements. Viscosity alone is not sufficient; trials should also assess solids content, flow, vacuum, and discharge.
