Product Overview
How it works
The rotor transfers energy to grinding media inside an enclosed chamber to disperse the slurry and reduce particle size. The laboratory system allows formulation and process settings to be evaluated before a larger production system is selected.
How to choose a laboratory configuration
Start with the material available for testing, viscosity, solids content, feed and target particle sizes, temperature limits, and contamination requirements. Compare WSM disc and BSM pin-type configurations through material trials rather than chamber volume alone.
Laboratory mill vs. production mill
Laboratory equipment supports small-batch development. A production system must also meet throughput, cooling, continuous-operation, and maintenance requirements. For upstream powder wetting, review the high-speed disperser. For viscous battery formulations, review the double planetary mixer.

Technical questions
Frequently Asked Questions
What is a laboratory bead mill used for?
It supports formulation development, feasibility testing, process optimization, material trials, and equipment selection before scale-up.
Is this series for wet or dry grinding?
This series is intended for wet grinding, dispersion, and particle-size reduction in liquid-based formulations.
What is the difference between WSM and BSM?
WSM denotes a disc grinding structure. BSM denotes a pin-type structure, which can be evaluated for applications requiring stronger grinding shear and finer results. Selection requires material testing.
What chamber sizes are available?
The listed effective chamber volumes range from 0.5 to 10 L. Use the model table to compare batch size, motor power, and reference flow rate.
Can the equipment be customized?
Yes. Grinding media, cooling, product-contact materials, and other configurations can be matched to material properties and process requirements.
Can laboratory trials support production scale-up?
Yes. Trial data can guide pilot testing, equipment selection, and production process design. Final production performance must be established for the actual formulation.
