       PLANETARY BALL MILL:-

        Make - Retsch Technology GmbH, Germany

        MODEL NO. –PM 100
       Planetary Ball Mill is used wherever the highest degree of fineness is required. In addition to mixing, for              size reduction
process and colloidal grinding, it provides the energy input necessary for the mechanical              alloying. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy        and therefore shorten grinding times.

  • Bio Tribometer Pin/Ball on Disc type

Make- Ducom Material Characterization Systems

Model- 836

Technical specification-

The Ducom BioTribometer is widely used for tribological investigation of materials replacing naturally occurring interfaces in joints. Currently available structural and lubricating materials are unable to reproduce low friction and wear response as observed in naturally occurring joints and lubricants. As a result, some structural biomaterials like UHMWPE or CoCrMo last for 10-12 years (average) whereas the natural joints can last for 60-70 years. There is an increasing need of novel materials to increase life span of the artificial joints. To promote such an environment there is a requirement for rapid testing (friction and wear) of biomaterials in accordance with and beyond the standards, and the BioTribometer serves this role with full compliance with ASTM and ISO standards.
