Generally, the ball diameter is between 20mm and 125mm. You can also design 10mm, 11mm or other diameters of steel balls. Small steel balls: 40mm or 60mm.
WhatsApp: +86 18203695377Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energyintensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
WhatsApp: +86 18203695377Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron and ...
WhatsApp: +86 18203695377Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
