    G-forces, enough to pulverize the toughest rocks, slags and ceramics. The single-clamp 8000M Mixer/Mill, known simply as “the Spex Mill” to thousands of users, has served spectroscopists and analytical chemists for over forty years. The clamp mechanism has changed little since the earliest versions, simply because it has proven extremely durable.

  • Page 9 8000M Mixer/Mill 5.0 OPERATION (Cont’d) 5.1 MIXING AND GRINDING Mixing is usually done in a plastic vial with plastic balls. Depending on the nature and amount of material to be mixed, one or several balls may be used. With a small amount of material and more than one or two balls, the impact may break the bottom of the plastic vial, so keep the number of balls to a minimum.

    If these bearings dry out they should be taken apart and re-greased. The 8000M Mixer/Mill is intended for intermittent use with running times that are typically 5 to 20 minutes long. Under those conditions it should run for many years without maintenance other than that described above.
