Laboratory Bead Mill

NMM Multi-functional Laboratory Bead Mill

The NMM multifunction experimental machine supports scaling up the experimental data to the NMM series mainframe using the same grinding system for mass production.

The Boyee NMM is an advanced Laboratory Bead Mill specifically engineered for small-scale R&D, formulation trials, and pilot-scale process development. As a true multi-functional Lab Bead Mill, it consolidates diverse grinding and dispersion requirements into a single compact system — with switchable rotor types, three agitator configurations, and a fully adjustable ceramic filter screen.

Constructed entirely from premium stainless steel with exceptional resistance to acids and alkalis, the NMM Laboratory Sand Mill is built to handle demanding experimental environments. Whether you are running a one-time small trial sand mill test or developing a repeatable lab-scale trial bead mill process, the NMM delivers consistent, reproducible results.

Most importantly, the NMM functions as a true pilot-scale bead mill: experimental data generated at lab scale (1.4L–20L per batch) can be proportionally transferred to the full NMM production series using the identical grinding system — enabling a seamless, data-backed transition from laboratory to mass manufacturing.

How the NMM Laboratory Sand Mill Works: A 4-Stage Grinding Process
01 - Feed & Rotor Selection

Material enters the grinding chamber of the NMM experimental sand mill through the feed inlet. Users select either the patented TurboMax turbine-type or pin-type rotor based on material viscosity and target particle size. High-speed rotating grinding media then subjects the material to intense shearing, impact, and friction — achieving nano-level fine grinding within the laboratory bead mill chamber.

02 - Post-Grinding Filtration

Ground material passes through a wedge-shaped or ceramic laminated disc filter screen. Larger particles and grinding media are intercepted; qualified material meeting the target particle size passes through and proceeds to discharge. This self-adjusting filtration is a core advantage of this lab-scale trial bead mill.

03 - Cyclic Grinding

Any material not meeting particle size requirements is automatically recycled back to the grinding zone for continued processing — a closed-loop system that maximizes grinding efficiency in small trial sand mill applications where material volume is limited.

04 - Discharge

Once particle size specifications are achieved, material exits through the discharge port, completing the full grinding cycle of this laboratory sand mill.

Optional rotors

The grinding system can choose turbine and rod pin according to the requirements:

Turbine rotor

Providing more gentle and meticulous grinding effect can effectively prevent excessive material dispersion and improve TurboMax patented Turbine(Turbo) structure grinding quality and accuracy

Rod pin rotor

The rod-pin rotor structure has high linear velocity, which can form continuous strong grinding in the grinding(Chamber), and the impact and grinding effect on the material is more intense

Optional materials

Zirconia

Polyurethane (PU)

Silicon Carbide
