The BIO-BK-VBM01 Vibration Mill is a benchtop sample preparation instrument designed for rapid size reduction of solid materials through high-frequency vibrational grinding. Operating at 1480 rpm with tungsten carbide grinding discs, this mill processes samples from 8mm feed size down to ≤0.074mm particles in 60-180 second cycles. The single-disc configuration accommodates 1-50g sample volumes in 100ml grinding vessels.
The unit features horizontal grinding force generation with quick-clamping sample loading and digital timing control. Equipped with motor protection systems and safety interlocks, the mill includes mobile casters for laboratory repositioning. Optional grinding disc materials (high chromium steel, agate, zirconia, corundum) allow material-specific sample preparation protocols while preventing cross-contamination.
How It Works
The vibration mill operates through high-frequency mechanical oscillation at 1480 rpm, generating intense grinding forces through tungsten carbide discs in horizontal motion. The sample and grinding media undergo rapid acceleration and deceleration cycles, creating impact and shear forces that fracture material particles. The horizontal grinding force direction ensures efficient energy transfer while preventing material compaction.
Sample size reduction occurs through multiple mechanisms including impact fracturing, attrition grinding, and shear stress. The 60-180 second grinding cycles provide controlled processing time, while the single-disc configuration maintains sample integrity. Digital timing control allows precise cycle duration for reproducible results across different material types.
Optional grinding disc materials (high chromium steel, agate, zirconia, corundum) enable material-specific protocols, with disc selection based on sample hardness, contamination sensitivity, and target particle size requirements.

Practical Tips
Establish baseline grinding times for your specific materials by testing small sample batches at different cycle durations.
Why: Material-specific calibration ensures consistent particle size results across different sample types and batches.
Clean grinding vessels and discs thoroughly between samples using appropriate solvents for your application.
Why: Prevents cross-contamination and maintains grinding efficiency by removing residual material buildup.
Pre-crush large samples to approximately 8mm feed size before grinding to ensure uniform processing.
Why: Consistent feed size maximizes grinding efficiency and reduces wear on tungsten carbide discs.
If grinding efficiency decreases, inspect discs for wear patterns and check clamping mechanism tightness.
Why: Worn discs or loose clamping reduces grinding force transfer and compromises particle size consistency.
Document grinding parameters (disc type, sample mass, time) for each material to establish reproducible protocols.
Why: Standardized parameters enable consistent results across different operators and sample batches.
Always verify complete motor stop and engage safety interlocks before opening grinding vessels.
Why: Residual rotation can cause sample spillage or injury during vessel handling and sample recovery.
Select grinding disc material based on sample hardness and contamination sensitivity requirements.
Why: Proper disc selection optimizes grinding efficiency while preventing sample contamination from disc wear.
Regularly inspect mobile casters and clean debris from wheel mechanisms to maintain positioning capability.
Why: Clean casters ensure smooth laboratory repositioning and prevent damage to flooring surfaces.

Background reading relevant to this product:
What particle size range can this mill achieve and how does grinding time affect final particle distribution?
The mill processes samples from 8mm feed size down to ≤0.074mm particles. Grinding time ranges from 60-180 seconds, with longer cycles generally producing finer particles, though optimal duration depends on material hardness and brittleness.
How do I select the appropriate grinding disc material for my sample type?
Tungsten carbide (standard) suits most applications. Use high chromium steel for hard materials, agate for contamination-sensitive samples, zirconia for trace metal analysis, and corundum for abrasive materials. Consult product datasheet for specific material compatibility.
What is the maximum sample throughput and how does batch size affect grinding efficiency?
Sample capacity ranges from 1-50g per batch in 100ml vessels. Smaller batches (1-10g) typically achieve more uniform size reduction, while larger batches may require longer grinding times or multiple cycles for equivalent results.
How does this compare to planetary ball mills or other size reduction methods?
Vibration mills offer faster processing cycles (60-180 seconds vs several hours) but with single-disc configuration versus multiple grinding stations. Best for rapid sample prep rather than ultra-fine grinding applications.
What maintenance is required and how often should grinding discs be replaced?
Regular cleaning between samples prevents cross-contamination. Grinding disc replacement frequency depends on material abrasiveness and usage intensity. Inspect discs for wear patterns and replace when grinding efficiency decreases.
Can this mill handle wet grinding or only dry materials?
The mill is designed for dry grinding applications. Consult product datasheet for specific guidance on sample moisture content limitations and vessel sealing capabilities.
What safety considerations apply during operation and sample handling?
Safety interlocks prevent operation with improper vessel installation. Motor protection systems guard against overload. Always verify complete stop before opening vessels and use appropriate PPE when handling processed samples.
How do I achieve reproducible results across different sample batches?
Maintain consistent sample mass, grinding time, and disc selection. Digital timing control ensures precise cycle duration. Document parameters for each material type to establish standardized protocols.
