How to Choose Milling Media and Milling Jars

Choose Material for Grinding Jars and Grinding Balls (Media)

Are you in the market for purchasing milling media and jars?  MSE Supplies, a U.S.-based business, carries a large assortment of milling media and jars for your needs. 

May we suggest, in order to prevent excessive abrasion, choose the hardness of the grinding jars and the grinding balls to be higher than that of the material used. We suggest that the grinding jars and milling media of the same material should be chosen to prevent damage.

Reference our guide on milling media applications and selection criteria for more in depth analysis on materials available to purchase at MSE Supplies for powder processing.
