Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

Mills and grinders are used for to break dry or wet samples into smaller particles by grinding, crushing, or cutting. Blades are used in mills to cut up samples into finer particles. Hand-held and bench top homogenizers blend chemical or biological samples thoroughly using various methods. Sonicators are homogenizers that use sound energy to ...

In addition to the instrument settings, the filling level of the jar is crucial for the success of the grinding process in mixer jar mills. A jar filling should consist of about 1⁄3 sample and 1⁄3 ball charge (pieces). The remaining third is the free jar volume that is necessary for the free movement of the balls.

Sampling Probes Description: This series of sampling probes are designed to sample granular, dry solids that are free flowing. They are used in applications such as granular minerals, granular ores and granular or free flowing powder chemicals.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
