Dry‑Wet Separation Planetary Ball Mill‑High‑Efficiency Fine Grinding Equipment for Laboratory

In scientific research fields including new‑material development, lithium‑ion cathode material research, metallurgy, mineral processing, chemical and pharmaceutical industries, sample pre‑processing grinding equipment directly determines the reliability and repeatability of experimental data. The dry‑wet separation planetary ball mill is specially developed for laboratory powder grinding. Compatible with both dry grinding and wet grinding processes, it can grind hard and brittle materials down to micron and sub‑micron level rapidly. It serves as core sample‑preparation equipment for university labs, new‑material enterprises and lithium‑ion R&D centers.

Relying on planetary motion effect combined with revolution and rotation, the grinding jars generate high‑intensity centrifugal force. Grinding balls inside jars deliver impact, friction and shear force to pulverize samples into ultra‑fine powder within short time. Adopting dry‑wet separation structural design, this unit flexibly switches between dry and wet working modes. It effectively prevents sample contamination, moisture residue and jar corrosion caused by cross‑usage of dry and wet processes, ensuring stable experimental results among batches.

• Separated design for both dry and wet grinding

Dry grinding and wet grinding can operate independently. It avoids moisture residue contaminating dry‑processed samples, and covers most powder pre‑processing scenarios with one single machine.

• Multiple grinding jar options to avoid sample contamination

Grinding jars in zirconia, alumina ceramic, stainless steel, PTFE are optional. For high‑purity lithium‑ion and rare‑earth materials, ceramic jars minimize metal impurity precipitation to satisfy strict requirements of advanced new‑material research.

• Intelligent programmable control system

Equipped with digital control panel. Users can freely set rotation speed, running duration, interval cycle and forward‑reverse rotation mode. The mill runs full grinding cycles automatically without on‑site monitoring, reducing manual error and guaranteeing experiment reproducibility.

• Stable operation & noise‑reduction protection

Precise dynamic balance calibration minimizes vibration during high‑speed operation. Closed housing reduces noise for indoor laboratory environment. Safety interlock function stops machine immediately once the cover opens for operator protection.

• Wide compatibility for diverse materials

Efficient pulverization and mixing for ores, quartz, metal oxides, lithium‑ion cathode & anode powder, ceramic powder and pharmaceutical intermediates. Suitable for small‑batch R&D as well as pilot‑scale sample preparation.

Select dry or wet grinding mode according to sample properties, choose matching jars and grinding balls. Filling volume should not exceed two‑thirds of jar capacity. Intermittent operation is recommended; avoid long‑term full‑load continuous running. Custom solutions are available for special requirements on jars, rotating speed and chamber structure.

Each unit is fully tested before delivery with operation manual provided. Sample testing service is available to support model selection. Professional technical support helps solve common challenges such as particle size control and powder agglomeration. Research institutes and new‑material companies are welcome to inquire for specifications and quotations.
