Ball Mixer Mill
The EQM-402 uses horizontal oscillation (up to 32 cycles per second) to drive grinding balls against the sample, achieving sub-10 µm in 1–4 minutes. Two bowls run simultaneously; it reduces fusion time and is the ideal compact benchtop unit for XRF pellet and fusion bead preparation.
Horizontal Oscillation + Rapid Homogenization
The EQM-402's horizontal oscillation mechanism drives grinding balls against the sample at high frequency. The result: homogeneous sub-10 µm powder in a short cycle and a measurable reduction in fusion time.
Application Areas
Frequently Asked Questions
Samples with a feed size below 5 mm typically reach sub-10 µm in 1–4 minutes. Time depends on ball diameter, sample hardness, and speed setting.
Two 50 ml bowls run simultaneously. This doubles laboratory throughput and reduces waiting time in routine analysis workflows.
Oscillation frequency and time are set via the touchscreen. The number and diameter (10–25 mm) of balls in the bowl control impact force; together they provide a wide achievable size range.
Yes. The instrument produces homogeneous sub-10 µm powders for blending with binder, pressing XRF discs or pellets, and reducing fusion cycle time.
Yes. The EQM-402 supports both dry and wet grinding. A liquid may be added to the bowl for specialized wet grinding applications.
