Characteristics:
- Used for grinding and dispersing low to medium viscosity water-based and solvent-based products.
- Compact and aesthetically pleasing welded frame, fixed to the ground with 4 foundation screws for stable and reliable operation.
- Uses a gap dynamic separator to separate materials and grinding media, which is not easy to block.
- The mixing plate is made of high wear-resistant alloy steel; its grooved design reduces sliding of the abrasive, strengthening abrasive flow for efficient dispersion.
- Hydraulic lifting with a cylinder that can rotate to a horizontal position, making disassembly, washing, and adjustment very convenient.
- Dispersity is inversely proportional to the flow rate of incoming materials — users can freely choose the liquid delivery volume to achieve the exact dispersity required.
- Grinding media can be glass, ceramic, or steel to achieve a wide range of performance, smooth operation, and very low noise.
Scope of Use:
- Automotive paint and industrial metal coatings
- Steel coil coating
- Industrial anti-corrosion coating
- Printing ink
- Varnish
- Screen printing ink
- Flexographic printing ink

Working Characteristics:
- Material enters the grinding chamber through a feeding pump; under a high-speed rotating mixing plate, strong shear force is generated between material and abrasive, quickly reaching the desired fineness.
- The material pump can be a pneumatic diaphragm pump or a variable-speed gear pump. A one-way valve prevents backflow of grinding medium, and a pressure gauge monitors chamber pressure (feeding stops automatically if pressure exceeds 3 kg/cm²).
- Forced cooling water flows through the grinding cylinder’s spacer sleeve, removing heat generated during grinding and keeping the material at low temperature for good dispersion.
- A thermometer at the discharge port displays the discharge temperature (auto shut-off if it exceeds the set value).
Feed Pump Options:
- Gear pump — electrically driven, adjustable pump speed via handle. Suitable for medium-to-high viscosity materials. Power: 1.1KW, Pump speed: 60–300 r/min.
- Diaphragm pump — Teflon diaphragm type, suitable for a wide range of material transport needs.
