Soil Planetary Ball Mill Grinding and Screening Instrument

1、 Working principle

For soil heavy metal analysis, four agate grinding tanks are required. The pressure of the sealed agate grinding tanks is set through a scale, and they rotate in the opposite direction around their own axis while revolving around the turntable axis. The samples in the tanks collide and rub against each other at high speed to achieve the purpose of crushing, grinding, mixing, and dispersing the samples. They can be ground dry, wet, or vacuum. Two or four grinding tanks can work simultaneously at a time.
