WhatsApp: +86 182036953775. Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which I need.
WhatsApp: +86 1820369537722 May, 2019. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically ...
