Pot Mill

Pot Mill

For analytically pure and contamination free micro milling of ceramic or metallic powder in dry as well as in suspension from as large as 200 micron particle size down to extreme fineness (Less than 1 micron). Most suitable for micro milling of hard material like carbide, Borides & ceramics etc.

Principle of Operation

Micro Milling is carried out by rolling of the balls on material as well as frequent impact of balls. The sample kept in the pot along with balls of suitable material and pot rotates on P.U. coated support rolls. The pot rotational speed can be set from 20-to 200 rpm. Pot rotates about its axis, while balls inside the pot spin about their own axis in the same direction, the material gets trapped between the inner wall of bowl & balls and gets rolled over by weight of balls and thus gets pulverized.
Pot Material (inner lining): a) Tungsten Carbide, b) Toughened Alumina or c) Stabilized Zirconia.
Pot Capacity 500 ml to 5000 ml (5 liters).
Long continuously running hours: - upto 7 days


  • Micro milling: End fineness, smaller than 1 micron.
  • Analytically Pure Milling: Since the material is kept in isolated bowl.
  • Reproducible Milling: Pot speed can be set from 20 to 200 rpm by selecting suitable roll speed through digital display settings. On - off cycle can be programmed for long running hours. Reproducible grinding results are achieved by selecting the previous set parameters.
  • Homogenizing: Homogenizing is achieved by continuous mixing during milling process.
  • Maintenance Free: System is driven through a self-diagnostic type micro controller based A.C. Frequency controlled drive, having various setting and indicating parameters.
  • Permanently lubricated bearings.
  • One Year Warrantee against any manufacturing Defects.
