Introduction of Hammer Kaolin Crusher: Hammer kaolin crusher is a kind of equipment that breaks material by impact energy. The machine can be divided into two forms: single rotor crusher and double rotors crusher. It is a crushing machine that can break the material about 600-1800 millimeters into 25 or 25 millimeters.
Palygorskite is used as drilling mud in these instances (Al-Ani and Sarapää,; 2008). Kaolin is the rock term for the mineral kaolinite which is a 1:1 phyllosilicate mineral. The structure of kaolinite is a tetrahedral silica sheet, alternating with an octahedral alumina sheet, joined by sharing a common layer of oxygens and hydroxyls.
