Inquiry (采购产品): Dry solids crushing / milling We have about 75 lbs. of a "clumped" dry solids mixture of diamond/sapphire and iron powder. It needs to be ground to its primary particle size for re-classification. We are in Allentown, PA. Can you perform this test grinding?? Please contact me. **** Hidden Message ***** Chip Ward 18109 Company: PPT Research, Inc. E-mail: chipward@pptresearch.com **** Hidden Message ***** chipward@pptresearch.com
