Jet mills and impact mills reduce particle size; laboratory classifiers separate size fractions. Select and evaluate each module for its own task.
Intuitive operation and low-maintenance construction keep long-term running costs to a minimum while maximising uptime.
Widely adopted in research facilities across the United States, France, Russia, and other markets.
Laboratory jet-milling, impact-milling and classification modules are configured for the material and trial objective.
Modular, user-friendly design streamlines setup, operation, and maintenance for any R&D workflow.
Proven worldwide - deployed in the U.S., France, Russia, and beyond for consistently reliable results.

The publicly described nano steam mill combines superheated steam with fine classification to explore submicron processing in a dry route. The name describes a technology direction rather than a nanoscale guarantee for every material. Agglomeration, analytical dispersion and whether the result is D50 or another metric all affect its meaning.
Information needed for selection
Provide a representative sample, D10/D50/D90 targets, test method, permitted phase change, impurity limits and steam availability. For nanoscale targets, distinguish primary particles from agglomerates.
Laboratory equipment establishes material response and an operating window. Compact, accessible construction supports research changeovers, but industrial capacity cannot be obtained by simply multiplying laboratory output by machine size. Define the test objectives first, then choose the module, contact materials and atmosphere, recording feed, energy, collection and analytical results.
Information needed for selection
Provide sample identity and safety information, existing test results, size/morphology/purity targets, available sample mass and intended industrial output. Sample quantity, timing and fees are agreed for the test plan.
Configuration changes let the platform address different tasks: particle-collision milling in jet mode, impact action in mechanical mode and size-fraction separation in classifier mode. Integration simplifies experimental setup, but does not imply all three functions operate simultaneously or have identical sample and throughput requirements.
Information needed for selection
Describe research objectives, sample types and changeover frequency, required modes, size/purity targets, laboratory utilities and space.
Equipment specifications depend on the feed and system conditions. These inputs establish a comparable trial plan and technical configuration.

Understand D10/D50/D90, cut size, yield, tap density, specific surface area and system-energy boundaries.
One size or efficiency number cannot describe a powder process. Measurement basis, dispersion, sampling location, feed and operating conditions define its meaning. Technical data should state what is measured, how it is measured and which stream/system boundary it represents.
These are the sizes at which the cumulative distribution reaches 10%, 50% and 90% on the stated basis. Laser diffraction commonly reports a volume distribution; specify volume, number or mass basis and dispersion conditions. Equal D50 values do not imply equal coarse and fine tails.
Cut size characterizes how particles of a given size partition between coarse and fine streams. Classification-efficiency definitions vary; provide the calculation and feed/product masses. Neither is the same quantity as product D50.
Yield may mean the mass of the target size fraction relative to feed; recovery may refer to total powder or a target component. Define numerator, denominator and treatment of recycle and retained material.
Sphericity describes similarity to a sphere in three dimensions and is not identical to two-dimensional image circularity. Aspect ratio can compare long/short axes or diameter/thickness for platelets. State imaging sampling and calculation methods.
Tap density is powder mass per settled volume under a specified tapping procedure; specific surface area is surface area per unit mass. Size, shape, porosity and methods influence both. Neither alone establishes electrochemical or other functional performance.
Low temperature needs a measurement point and run duration. Contamination control requires contact materials, analytes and detection limits. Specific energy uses acceptable product mass as its denominator and states inclusion of compression, steam, classification, collection and drying.

Jet mill · Equipment illustration
Grinding & Pulverizing
The LNJ Jet Mill utilizes multiple nozzles to generate high-velocity, sonic-speed airflow, enabling ultrafine pulverization of materials through particle-on-particle collisions. The finely ground particles are then carried into a high-efficiency turbine classifier, where oversized particles are separated and returned to the grinding chamber for further processing.

Grinding & Pulverizing
The LNPE Impact Mill combines two size-reduction mechanisms - high-speed hammer impact and hammer-to-liner compression - to achieve ultrafine grinding in a single continuous process. After comminution, material enters the built-in turbine classifier.
