Mixer/Mill® - High Energy Ball Mill - Instrument Solutions

The 8000D Mixer/Mill of SPEX SamplePrep is a powerful ball mill that pulverizes hard or brittle samples until they are fine enough for analysis. The sample is placed in a Grinding Vial with one or more balls after which it is shaken vigorously. The clamp containing the Grinding Vial moves back and forth with a short lateral movement in the form of an 8, producing large G-forces.

Ball, Pebble and SAG Mills: A Buyers Guide

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

Ball Mill - an overview | ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
