Process Engineering
A high-speed disc circulates the sample through a removable media-filled basket.
Repeated media impact and shear disperse agglomerates in the same laboratory vessel.
Speed, time, temperature, and media charge provide the basis for comparing formulations.
Equipment Benefits
Combines laboratory dispersion and grinding in one vessel.
Removable basket simplifies cleaning and formulation changes.
Polymer basket options can limit discoloration and resist solvents.
Variable speed supports repeatable product development.

Equipment Guidance
Depending on media size, rotor geometry and the number of passes, the Laboratory basket mill reaches 5 - 20 micron depending on media. The endpoint is confirmed on your own material in a trial run, so the configuration matches your formulation rather than a catalogue figure.
The mill runs with high-purity zirconia or ceramic media selected to the target fineness and the separator opening. Chamber and rotor options are chosen to suit the material; product-contact parts are Stainless steel 304 / 316L.
Capacity is 1 - 20 L, with motor power 0. The model is selected from your batch volume, solids loading and required cycle time.
Typical duties cover Architectural Paints, Printing Inks, Industrial Coatings. POLYC reviews your material data before recommending a chamber, media size and pass count.
Provide the material type, starting and target particle size, solids loading, batch volume and required throughput. POLYC returns a configuration with media recommendation and an expected pass count.
A laboratory basket mill is used for formulation development, color matching and small-batch trials of paints, inks, pigments and coatings. It grinds and disperses in the same vessel used for pre-mixing, so trial conditions mirror production equipment and the resulting process data can be scaled up.
Choose a laboratory basket mill for flexible small batches, frequent color changes and process data that scales to a production basket mill. Choose a laboratory bead mill when you need continuous circulation and finer particle sizes for battery materials, nanosuspensions or ceramic slurries.
Yes. Because the laboratory unit uses the same basket-and-disc grinding principle as production models, fineness, cycle time and media selection transfer directly to larger PZM baskets, so scale-up is a capacity change rather than a process redesign.
