Prepared from Yushun’s 2026 product selection manual. Model data is preliminary selection guidance and requires engineering review. The dispersion-disc linear velocity is printed in the source as a single merged value (0–23 m/s) across all models, so per-model figures must be confirmed. Extrusion, vacuum, temperature-control and tank-change configurations are project specific.
Product Overview
How it works
Planetary blades revolve around the tank axis while rotating on their own axis, and a separate high-speed dispersion shaft handles powder wetting and agglomerate breakdown. The machine adds an integrated extrusion and discharge unit, a hydraulic lift for the upper frame, and exchangeable tanks.
How to choose
Define the formulation, viscosity and solids content, the batch size, the required vacuum and temperature profile, the discharge form, and how tanks will be handled between products. Standard table values are preliminary references; the linear-velocity figure is a single merged value in the source and needs engineering confirmation per model.

Equipment configuration
Core Features
- Planetary mixing with a separate high-speed dispersion shaft, combined with an integrated extrusion and discharge unit.
- Sealed tank supports vacuum operation for deaeration.
- Jacketed tank for heating or cooling, configured to the formulation.
- Exchangeable tanks with precision-machined inner walls for faster cleaning and product changes.
- Planetary and dispersion shafts are both variable-frequency driven to suit different materials and process stages.
- Rotating scraper keeps material off the tank wall during mixing.
- The upper frame lifts hydraulically so tanks can be changed quickly.

Technical questions
Frequently Asked Questions
How does this differ from the standard double planetary mixer?
The source describes an integrated mixing-and-extrusion machine with a hydraulic lift and exchangeable tanks, on a cabinet base. Compared with the standalone double planetary mixer, the extrusion unit and discharge arrangement are the distinguishing features. The exact configuration for a project is confirmed in the technical proposal.
Which working volumes are listed?
The reference table covers 2 L, 5 L, 10 L and 20 L working volumes with their tank design volumes. Working volume and tank design volume are different values and should not be used interchangeably.
What viscosity range applies?
The manual gives approximately 10,000–1,000,000 cP. Rheology, solids content, temperature and batch size must be evaluated in material trials before selection.
Is vacuum operation available?
Yes, the tank is sealed for vacuum operation. The required vacuum level, pressure reference, holding conditions and acceptance method must be agreed in the project specification.
Why is the linear velocity shown as one value?
The source table prints a single merged 0–23 m/s value for all models. Per-model linear velocity depends on the disc diameter and speed, and must be confirmed by engineering.
Can the tank be changed between products?
The design uses exchangeable tanks with a hydraulic lift. Cleaning validation, changeover procedure and spare-tank supply are project-specific.
