Laboratory Ball Mill 2 kg, Motor Driven, SS 304 Chamber, SS Grinding Balls, 80 RPM
Couldn't load pickup availability
2 kg capacity motor-driven laboratory ball mill for sample preparation in mineral analysis, pharmaceutical formulation, ceramics, cement, coal, and metallurgical labs. 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 (mixed sizes). 80 RPM rotation speed, precision-balanced rotating parts for low-vibration and quiet operation. 220V AC single-phase. $1,499 direct, versus $3,500-$8,000 for Retsch PM100 / Fritsch Pulverisette 5 / SPEX 8000M laboratory ball mills.

FAQ
How does this compare to a Retsch PM100?
Retsch PM100 is a planetary ball mill (higher energy density, faster grinding to nanoscale, wider RPM range 100-650). Ours is a rotational ball mill (simpler mechanism, 80 RPM fixed, longer grind times to reach same particle size). For most analytical prep and traditional Ayurvedic work, this SciMed unit is fully adequate. For nanoscale and high-energy mechanochemistry, PM100 is required. Price differential: $1,499 vs $6,500-$8,500.
Can I use different grinding materials?
SS 304 balls and container ship standard. Agate (contamination-free for trace analysis), zirconia (harder and wear-resistant), tungsten carbide (highest hardness for very hard samples), and hardened chromium steel (industrial grinding) balls and containers available as accessories on request.
What particle size can I achieve?
Typical 10-100 μm final particle size depending on starting material and grind time. Softer materials (organics, Ayurvedic herbs) reach 10-30 μm in 30-60 min. Harder materials (rock, ceramic) take 2-4 hours to reach 50-100 μm. For sub-micron / nano grinding, planetary ball mills are required.
How much sample per batch?
2 kg batch capacity means you can grind up to 2 kg of raw material per run, typically fill container 30-50% to leave room for balls and head space. Grinding balls should equal 30-40% of container volume.
What's the warranty?
1-year parts and labor. Motor 3-year warranty. Grinding balls and container are consumables (wear during use); replacement stocked in San Jose.
