Product Overview
How it works
The WSM series uses a disc-and-pin dispersion structure to transfer energy through the grinding media into the slurry. A high-flow separation screen retains the media while the processed slurry passes through. Cooling and seal configuration are part of the process design, not independent choices.
How to choose a continuous grinding configuration
Provide the resin or liquid system, pigment or filler, feed and target particle sizes, viscosity, required hourly output, temperature limit, and acceptable contamination level. Compare the model-specific motor power, batch capacity, and reference flow rate below. The reference table does not establish a universal throughput guarantee.
Disc high-flow vs. pin-type nano grinding
For coatings and inks, a high-flow disc configuration can be evaluated for continuous production, while a pin-type nano bead mill can be compared for more demanding shear and fineness requirements. Cooling, grinding media, and material trials determine the final selection.
Process integration
A high-speed disperser can provide upstream powder wetting and pre-dispersion. Use a laboratory bead mill to evaluate the formulation before scale-up. See the paint and coatings application for process context.

Technical questions
Frequently Asked Questions
What is a disc high-flow bead mill used for?
It is used for continuous wet grinding and dispersion of industrial slurries, including coatings, inks, pigments, ceramic slurries, and battery materials. It should be selected for the required particle size, throughput, and operating conditions.
What does the disc-and-pin structure do?
The structure promotes energy transfer between the grinding media and the slurry for dispersion and particle-size reduction. The achievable result depends on the material and grinding process.
What chamber sizes are listed?
The WSM reference table covers effective grinding chamber volumes from 30 to 3000 L. Chamber volume is not the same as batch capacity or hourly throughput.
Are the listed flow rates guaranteed production rates?
No. The table provides preliminary reference ranges in kg/h. Actual flow and output depend on slurry viscosity, feed size, target fineness, grinding process, and configuration, and must be confirmed through testing.
How does the mill manage cooling and sealing?
The design uses spiral forced-water circulation channels, multipoint cooling, and an integrated double mechanical seal. Cooling duty and seal lubrication must be matched to the formulation and operating conditions.
Can wear components and contact materials be selected?
Yes. Inner chamber and dispersing components can be replaced. Material options include alloy steel, ceramics, polymers, and stainless steel, subject to the formulation and wear requirements.
What controls and monitoring are available?
Options include explosion-protected push-button controls or PLC touchscreen controls, plus feed-pressure, outlet-temperature, and seal-lubrication-level monitoring. Safety standards and the applicable configuration require project confirmation.
Should I choose a disc high-flow mill or a pin-type nano mill?
Evaluate the disc high-flow series when continuous flow and production capacity are priorities. Compare a pin-type nano mill when stronger shear and finer particle-size control are important. Confirm the choice using the actual formulation rather than the product name alone.
