XQM Planetary Ball Mill Four Jars 0.1 Micron Fine Grinding Lab Sample Preparation Machine

Sample preparation throughput is the deciding factor in many analytical laboratories, and the XQM four-jar planetary ball mill is designed exactly for that pressure point. It processes four samples in parallel and reduces material down to 0.1 micron, which makes it a practical workhorse for geology, mining and materials laboratories preparing powders for XRF, XRD, spectroscopy and other instrumental analysis.

Beyond routine sample preparation, the mill also supports nanomaterial dispersion, new product development and small-batch production, giving one compact machine the versatility of several devices.

• Four samples per cycle: the four-jar turntable design multiplies daily output for high-volume preparation work.
• 0.1 micron capability: ultra-fine grinding meets the strict particle specifications of modern analyzers.
• Vacuum jar compatibility: an optional vacuum jar protects sensitive samples during the grinding cycle.
• Dry and wet grinding: both methods are supported, covering ores, ceramics, chemicals and polymers.
• Programmable operation: speed, forward and reverse timing and total duration follow your standard procedure.
• Quiet precision mechanics: CNC-machined parts, a cast planetary plate and precision gears keep noise and vibration low.

As the turntable revolves, each jar simultaneously rotates on its own axis, so the grinding media inside receive energy from two superimposed movements. The result is intense impact and friction that quickly breaks particles down to the target size. Two or four jars can be engaged at once, and because all jars experience identical motion, batch-to-batch consistency is easy to maintain.

Rotational and revolution speeds vary by model within the series range; exact values should be confirmed with our engineers when selecting a model.

The mill is widely adopted for ore and rock powder preparation in mining laboratories, sample grinding in geological surveys, and material development in ceramics, electronics, chemical and pharmaceutical research. It is equally useful in university teaching laboratories where students need fast, reproducible results.
