Inquiry (采购产品): grinding aid Dear Sir or Madam, Our company is presently involved in fine grinding vulcanized crumb rubber. We are doing this in specially designed roller/cracker mills. We are having difficulty with aggregation/mechanical devulcanisation (clumping) at particle sizes below approximately 400um. We are about to commence our second round of testing (at Akron Ohio) and are seeking advise. We can use a Si based flow separator for screening, but find that when using these flow aids to assist grinding, they smear in our roller mills and aggravate clumping. We have been advised to try Calcium carbonate, but have not been able to locate a supplier who can recommend a specific grade or type. Can you assist with supply and technology, or recommend a suitable alternative?
