PZM Basket Mill: Submersible Wet Grinding for Paint, Ink, Pigment & Latex Production
The POLYC PZM basket mill is a submersible wet grinding mill for industrial paint, ink and pigment production. Whether the duty is a basket mill for industrial paint, a basket mill for ink, a dye basket mill or a basket bead mill, one platform covers 30-1,500 L batches, and the same machine is also specified as an ink basket mill, a paint basket mill or a pigment miller for pigment paste. It lowers directly into the mixing vessel, so one mill can serve multiple tanks. The basket and vessel use a double-wall jacket for cooling, which keeps material temperature stable during grinding.

Where the PZM Basket Mill Performs Best
Industry ApplicationsWidely used for wet grinding and dispersion across multiple industries. Its submersible design and fast cleaning make it ideal for facilities running many colors or product types.
🎨
Paint & Coatings
As a basket mill for paint and coatings, the PZM series handles both water-based and solvent-based formulations with excellent fineness control. The double-wall cooling jacket prevents temperature rise during high-shear grinding, which is critical for heat-sensitive resin systems. Ideal for architectural coatings, industrial paints, wood coatings and protective coatings where frequent color changes are common.
🧪
Pigments & Color Pastes
For basket mill for pigment applications, the mill achieves efficient dispersion of organic and inorganic pigments including titanium dioxide, iron oxides, phthalocyanines and quinacridones. The basket design minimizes grinding media usage while maintaining high grinding efficiency, making it cost-effective for high-value pigment pastes and color concentrates.
🚗
Automotive Refinish & OEM
As a basket mill for automotive paint, the PZM series meets the stringent fineness and cleanliness requirements of automotive refinish and OEM coatings. The closed basket design prevents contamination and solvent evaporation, while precise temperature control ensures consistent batch quality for basecoats, clearcoats and primer surfacers.
🪓
Latex & Emulsion Paints
For basket mill for latex and emulsion paint production, the mill handles high-viscosity latex formulations with effective pigment wetting and dispersion. The submersible basket lowers directly into the mixing tank, eliminating transfer pumps and reducing material loss — ideal for small-batch tinting and medium-scale production.
🖨
Inks & Printing Inks
Widely used for ink production, including offset, gravure, flexographic and screen printing inks. Its ability to achieve fine particle size distribution (down to 5 microns or finer) ensures excellent print quality, color strength and gloss. Easy cleaning between colors reduces downtime in multi-color environments.
🌾
Agrochemicals & Specialty
Beyond coatings and inks, the basket mill serves agrochemical SC (suspension concentrate) formulations, pesticide dispersions, battery materials, ceramic slurries and other specialty chemical applications requiring fine wet grinding and stable dispersion.

Choosing the Right Basket Mill
How to Choose1
What fineness do you need?
< 20 μm → standard disc type · < 10 μm → pin type · < 5 μm → high-energy type with 0.5 mm media
2
What is your batch size?
30–100 L → lab / pilot model · 100–500 L → production model · 500–1,500 L → heavy-duty model
3
How often do you change colors?
Daily color changes → basket mill (fast cleaning). Continuous single-product runs → horizontal bead mill (higher throughput).

Beyond general paint and pigment work, the PZM is frequently specified as a basket mill for printing ink. In publication and packaging plants it runs as a gravure ink basket mill and a flexo ink basket mill, where fast colour changeover matters more than continuous throughput. The same basket serves as a printing ink basket mill for offset and screen inks.
In automotive and industrial finishing it is used as an automotive paints basket mill and a primers paint basket mill for refinish primers, and as a top coating basket mill where a single vessel has to handle base coat and clear coat batches in sequence.
Pigment and agrochemical producers use the identical platform as a pigment basket mill and a pigment paste basket mill for high-concentration colour paste, and as a pesticide basket mill where agrochemical SC batches must be ground without cross-contamination between products.

Process Engineering
Working Principle
- 1
The basket is lowered into a mobile vessel containing premixed material.
- 2
A high-speed disc circulates product through the media-filled basket, where impact and shear disperse agglomerates.
- 3
Processed material returns directly to the same vessel, creating repeated batch circulation without external piping.
- 4
Jacketed basket and vessel surfaces remove heat during the grinding cycle.

Frequently Asked Questions
What is a basket mill?
A basket mill is a submersible wet grinding machine that combines premixing, dispersion, and grinding in one vessel. POLYC MACHINE basket mills support laboratory and production batches for coatings, inks, and battery materials.
Basket mill vs horizontal bead mill?
Basket mills are submersible and suit small-to-medium batches with easy cleaning. Horizontal bead mills are continuous-flow machines for higher-volume production. POLYC MACHINE engineers can recommend the right configuration.
What capacity range do your bead mills support?
POLYC MACHINE bead mills range from laboratory models to 1,000 L production machines. Custom configurations are available for specific materials, viscosity, and throughput requirements.
What materials are bead mills suitable for?
Our bead mills process coatings, inks, battery materials, pharmaceuticals, cosmetics, agrochemicals, advanced ceramics, and chemical products. Material testing can be arranged before purchase.
How do I choose the right bead mill?
Consider batch size, material viscosity, target fineness, and production volume. POLYC MACHINE engineers provide consultation and material testing to recommend a suitable machine.
Which is better for small batch production?
A basket mill is better for small batches and frequent color changes. It requires 5-15 minutes of cleaning with low solvent use, compared to 30-90 minutes for a horizontal bead mill. A horizontal bead mill is more suitable for high-volume continuous production where cleaning frequency is lower.
What is a basket mill used for?
A basket mill is used for batch wet grinding and dispersion of pigments and fillers in ink, paint, coatings and adhesives. The grinding basket lowers into the same vessel used for pre-mixing, so material is transferred only once—ideal for frequent color changes and small-to-medium batch production.
What is the difference between a basket mill and a bead mill?
A basket mill works batch-wise in a single vessel, while a horizontal bead mill circulates material through a sealed chamber for continuous, finer grinding. Choose a basket mill for flexible small-batch production and quick color changes; choose a horizontal bead mill for continuous production and very fine particle sizes.
How often do I need to replace grinding media?
Zirconia beads last 8,000-12,000 hours under normal operation. Glass beads need replacement every 1,500-3,000 hours. Actual lifespan depends on material hardness and disc speed.
How long does it take to change from one color to another?
About 15 minutes: lift the basket, rinse with solvent or water, wipe the disc and basket screen, then lower into the next tank. No pipe flushing is needed.
How much does a basket mill cost?
Pricing depends on capacity, contact materials and configuration rather than a single list price. Share your batch volume, material and target fineness, and POLYC will return a quotation with the recommended model.
What is a basket mill for industrial paint used for?
A basket mill for industrial paint replaces a separate disperser and bead mill. The basket is lowered into the batch so dispersion and grinding happen in one vessel, and the same unit can serve several tanks. It suits pigment paste, ink and coating batches from 30 to 1,500 litres.
Can one basket mill handle ink, dye and pigment paste batches?
Whether the duty is a basket mill for ink, a basket mill for industrial paint, a dye basket mill or a pigment paste batch, the same PZM covers it: it works as an ink basket mill, a paint basket mill and a pigment miller with one basket. Changeover is done by lifting and cleaning the basket, so switching shades takes minutes. With grinding media loaded it becomes a basket bead mill for finer dispersion.
