Laboratory Ball Mill 2kg Heavy Duty — 110-220V Motor Driven, SS 304 Container + Grinding Balls
Couldn't load pickup availability
2 kg capacity heavy-duty motor-driven laboratory ball mill for sample preparation in mineral analysis, pharmaceutical formulation, ceramics, cement, coal, and metallurgical labs. Universal 110-220V AC voltage (works globally without adapter). Grinds hard and brittle materials down to fine powder (typically 10-100 μm) with minimum loss of moisture or volatile constituents. Includes SS 304 grinding container and stainless steel grinding balls. 80 RPM rotation speed, precision-balanced rotating parts for low-vibration + quiet operation. $1,499 direct — versus $3,500-$8,000 for Retsch PM100 / Fritsch Pulverisette 5 / SPEX 8000M laboratory ball mills.

FAQ
What's the difference vs the standard Ball Mill 2kg variant?
This variant runs on universal 110-220V AC (auto-detecting). The standard variant is 220V-only. Same capacity, same SS 304 chamber, same grinding media, same 80 RPM. Same price. Choose this if you're US-based (110V) or need voltage flexibility across international sites.
How does this compare to a Retsch PM100?
Retsch PM100 is a planetary ball mill (higher energy density, faster to nanoscale, 100-650 RPM). Ours is a rotational ball mill (simpler mechanism, 80 RPM fixed, longer grind times). For analytical prep + traditional Ayurvedic work, this is fully adequate. For nanoscale grinding, PM100 is required. Price differential: $1,499 vs $6,500-$8,500.
What particle size can I achieve?
Typical 10-100 μm final depending on starting material + grind time. Softer materials (organics) reach 10-30 μm in 30-60 min. Harder materials (rock, ceramic) take 2-4 hours to reach 50-100 μm.
What's the warranty?
1-year parts + labor. Motor 3-year. Grinding balls + container are consumables; replacement stocked in San Jose.
