Core Technology & Working Principle
A high speed disperser does one job: it puts powder into liquid and breaks the agglomerates apart in the shear zone at the disc rim. The saw-tooth disc turns fast enough to form a vortex that draws powder down from the surface and into the zone where the teeth generate local shear. Everything that follows — milling, let-down, filtration — depends on whether this step was done properly, which is why the parameters need to be recorded rather than judged by eye.
▲ Tip Speed at the Disc Rim
Shear is generated at the saw teeth, and tip speed rises with disc diameter and rpm. A recorded rpm with a known disc diameter is a reproducible specification; a dial position is not.
▲ Vortex Draws Powder In
The disc has to turn fast enough to pull a vortex that carries powder down into the shear zone. Below that speed the powder floats on the surface no matter how long the batch is mixed.
▲ Disc-to-Tank Ratio Governs Scale-Up
Keeping the disc-to-tank diameter ratio and the tip speed constant is what makes a bench trial predictive. Change either and the production batch will not behave like the sample.
Precision Engineered Details
These are the parts an operator touches every shift: the disc, the lift, the clamp and the drive cabinet.
BPF-H Technical Parameters
Two models cover 5 to 80 litres. Choose by batch size, then check the available disc diameters and the stroke against the vessels you actually use.
| Model | Motor Power | Operating Speed | Disc Diameter | Lifting Stroke | Batch Capacity | Dimensions (L×W×H) |
|---|---|---|---|---|---|---|
| BPF-H-1.1 | 1.1 kW | 0 – 3,000 rpm | Φ100 / Φ120 mm | 500 mm | 5 – 30 L | 720 × 600 × 1,320 mm |
| BPF-H-2.2 | 2.2 kW | 0 – 1,500 / 3,000 rpm | Φ120 / Φ150 mm | 600 mm | 20 – 80 L | 720 × 650 × 1,450 mm |

Our Manufacturing Advantages
🏢 Direct Source Factory
Shanghai Polyc Technology Co., Ltd. is not a reseller. Every BPF-H laboratory disperser is machined, assembled and tested at our Wuxi plant, so you buy at the factory price and speak directly to the engineers who built it.
✈️ 30–45 Days Fast Delivery
Standard models ship in 30–45 days from confirmed drawings, thanks to our integrated vertical in-house production lines.
🛡️ Strict Quality Control
Key welds, seals and running accuracy are inspected before assembly, and each machine is run at the factory before packing.
🔧 3-Year Global Warranty
Every unit is covered for three years, with remote video support and spare parts stocked for dispatch worldwide.
Target Application Spectrum
The disperser is the first machine in most wet processes, so it is specified wherever a powder has to enter a liquid reproducibly. The four duties below cover most of the demand.
Paints & Coatings R&D
White base and tint paste trials where the pre-dispersion step decides how much milling the batch still needs.
Ink Formulation
Pigment wetting for solvent, water-based and UV ink systems, tested at pilot volume before the mill is committed.
Adhesives & Sealants
Filler and thickener incorporation into a resin base, where the disc has to keep a rising viscosity moving.
Small Batch Production
Short runs and custom shades where setting up a production line is not economic and 20 to 80 L is the whole order.
Need a Pilot Disperser Between the Beaker and the Plant?
Send us the batch volume, the product viscosity and the disc diameter you have in mind — our engineers will confirm the model, the disc and the vessel clamp, then quote directly from the Wuxi factory.
