Laboratory Bead Mill - RotoMate I

Laboratory Bead Mill - RotoMate I


  • Compact user friendly design.
  • Suitable for continuous circulating batch operation.
  • Minimal loss of product.
  • Significant result within short span of time.
  • Use of small grinding media of 0.6mm for grinding down to nanometer range.


The Bead Mill is used for fine milling, dispersion, homogenisation of a suspension.

The milling/dispersion system in a Bead Mill consists of a Milling Chamber & an Agitator with discs or pegs.The Chamber is filled with zirconia beads & the product to be dispersed.

In the milling chamber, the grinding media is kept moving by the motor driven agitator & the product to be dispersed is pumped into the chamber through peristaltic pump.As the grinding media collides & rolls about each other, the solid particles caught between them are gradually reduced in size.

The milled product is separated from the grinding media at the outlet by a slotted screen or a gap separator, collected in a vessel &  re-circulated back into the chamber via the same pump, while being continuously stirred in the same collecting vessel.

  • Pharmaceuticals: Bead mills are used for nano particle size reduction applications in oral doses, inhalants and opthalmics.
  • Paint,pigment & Dyes: Horizotal bead mills are used for wet milling of organic and in-organic pigments to ultrafine particles.
  • Printing Ink: Our bead mills are capable of handling high viscous products and suitable for all types ( pasty, liquid and inkjet ) of inks.
  • Cosmetics: Development of sunscreen, foundation, eye shadow etc.
  • Agrochemicals ( Pesticides & Fertilizers): For grinding low-viscous and temperature sensitive materials.
