Dry beneficiation is generally used to process bentonite with better raw ore quality, or bentonite-rich ore with montmorillonite content of more than 80%.This method is to dry the raw ore in the sun, air dry it naturally or dry it in the oven. It is first crushed manually or with a jaw crusher, and then crushed with a Raymond mill and other roll …
