14 th AusIMM Mill Operators Conference, 29 31 August 2018, Brisbane, Australia. ABSTRACT. The Karara iron ore project is a magnetite operation consist of open pit mining and concentrator to produce high grade magnetite concentrate. The concentrator has adopted three stages of comminution, ie fine crushing in the high pressure grinding rolls , primary ball milling and fine grinding in the TowerMill plus magnetic separation in between these comminution devices.
The ball mill is a typical material grinder machine which widely used in the mineral processing plant, ball mill performs well in different material conditions either wet type grinding or dry type, and to grind the ores to a fine size. Main ball mill components: cylinder, motor drive, grinding medium, shaft. The cylinder cavity is partial filling with the material to be ground and the metal grinding balls.
The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as, for the dry materials process, the shell is dustproof to minimize dust pollution.
DOVE Ball Mills are used in supplied and applicable for wet and dry grinding applications within the following branches of industries: ·. Mining, Hard Rock Gold Mining Application, as well as Platinum base metals, Base Metals, Ferrous Metals, and light metals. Construction and Agregate applications.
AMIT 135 Lesson 7 Ball Mills CircuitsMining Mill . For primary grinding the ratio could vary between 1 1and 1.8 1 For fine regrinding in open circuit the ratio ranges from 1.3 1 to 1.5 1 Some ball mills are separated in to compartments by grates The grates hold back particles above a certain size for additional grinding The compartments could ...
