On selecting large media
Large Media refers to any media greater than 4 mm (3/16") in diameter.
Most of the questions on our media selection form are valid for large media as well. If you fill in the questionnaire, we can give you a personalized consultation, but we also offer the rules below as general guidelines.
We have listed pros and cons of specific media on our product specification pages for large ferrous and non-ferrous media.
Rules for selecting large media
Rule 1: The media must not "float" in the product. Viscosity and density action must not be impaired.
Rule 2: The media specific gravity MUST NOT be greater than that of the mill liner UNLESS the liner is elastomeric (example: rubber or urethane).
Rule 3: The media must not destroy the product value through color change, abrasive contamination or chemical reaction.
Rule 4: The media should promote highest thru-put per unit of time. Small is desirable if Rule 1 is met.
NOTE: Static electrical charges will develop in all non-ferrous medias. Fire or explosion hazard may exist.
