Ball mills

Ball mills — available models

• 

  Grinding media (balls) for mills

  Grinding media — balls and beads for ball and stirred mills in eight materials: zirconia (ZrO₂), agate, corundum (Al₂O₃), 304/316 stainless steel, tungsten carbide, polyurethane, nylon and silicon nitride. Diameters from sub-1 mm beads to 40 mm balls, matched to the sample, jar and target fineness.

  • Eight materials — zirconia (ZrO₂), agate, corundum (Al₂O₃), 304/316 steel, tungsten carbide, polyurethane, nylon, silicon nitride
  • Diameters from sub-1 mm beads to 40 mm balls
  • Zirconia 94.8% ZrO₂ — density ≥6 g/cm³, hardness ≥1250 HV
  • Selection rule — balls harder and denser than the sample and jar walls

  Small ball mill RJM30D

  The small RJM30D laboratory roller ball mill for small samples — three rollers, speed 0–480 rpm and vessels around 65–85 mm in diameter. A compact solution where a large ball mill is unnecessary.

  • Compact roller construction (3 rollers)
  • Speed 0–480 rpm
  • Vessels around 65–85 mm in diameter
  • Vessels and balls in ceramic, agate, steel, zirconia

• 

  Stirred (bead) mill

  A laboratory stirred (bead) mill for wet grinding and dispersion down to nano fineness. An agitator drives fine grinding beads through a slurry, breaking down pigments, paints, inks, ceramics and advanced materials — with temperature control for viscous media.

  • Wet grinding and dispersion down to nano fineness
  • Agitator + fine beads (below 1 mm)
  • High-viscosity slurries, temperature control
  • Pigments, paints, inks, ceramics, advanced materials

• 

  Vibration ball mill

  A laboratory vibration ball mill for fast, ultra-fine grinding of hard, brittle and fibrous samples. High-frequency vibration of the chamber breaks the material down in minutes — dry or wet, in small batches for sample preparation.

  • High-frequency vibration — grinding in minutes
  • Ultra-fine result for sample preparation
  • Hard, brittle and fibrous materials
  • Dry and wet grinding

  GQM multi-position ball mills

  GQM multi-position ball mills for parallel grinding of many samples — available in 2-, 4- and 8-position versions, for 5–20 l vessels and speeds up to 410 rpm. Vessels and balls in various materials — steel, zirconium oxide, aluminium oxide, agate.

  • 2-, 4- and 8-position versions for parallel work
  • Vessels of 5, 15 or 20 l capacity
  • Speed up to 410 rpm
  • Vessels and balls in steel, zirconia, alumina, agate
  →
• 

  QM roller ball mills

  QM roller laboratory ball mills for accurate grinding and mixing of samples — single-position, with adjustable roller spacing for 0.5–15 l vessels. No dedicated clamps, so they work with vessels from different makers.

  • Single-position QM-5 and QM-15 roller mills
  • Adjustable roller spacing — vessels 0.5–15 l
  • Works with vessels from different manufacturers
  • Speed 40–410 rpm depending on the model
  →
• 

  Large ball mills RJM102 and RJM103

  Large laboratory ball mills RJM102 and RJM103 for demanding applications — a maximum load up to 40 kg, speed 0–600 rpm and a time setting up to nearly 100 hours. Robust construction and a wide choice of vessels and grinding balls.

  • Large maximum load — up to 40 kg
  • Speed 0–600 rpm
  • Time setting up to 99 h 59 min
  • Durable, robust construction for intensive work
  →
• 

  XQM planetary ball mills

  XQM planetary ball mills for very fine reduction — four sample-processing positions, dry and wet grinding and a final fineness around 0.1 µm. Speed up to 670 rpm and continuous operation for long grinding cycles.

  • Final fineness around 0.1 µm
  • Four sample-processing positions
  • Dry and wet grinding of various materials
  • Speed up to 670 rpm, continuous operation

• 

  Grinding jars (bowls) for ball mills

  Grinding jars (bowls, chambers) for planetary and roll ball mills in eight materials — agate, zirconia (ZrO₂), corundum (Al₂O₃), 304/316 stainless steel, tungsten carbide, nylon, PTFE and polyurethane. Volumes from 50 ml to 5 L, matched to sample hardness, required purity and grinding mode.

  • Eight materials — agate, zirconia (ZrO₂), corundum (Al₂O₃), 304/316 steel, tungsten carbide, nylon, PTFE, polyurethane
  • Volumes from 50 ml to 5 L (50, 100, 250, 500 ml; 1–5 L)
  • Versions for planetary (XQM) and roll (QM, RJM, GQM) mills
  • Material matched to sample hardness and acceptable contamination
