AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:
Ball Mill (Ball Mills Explained)
Crushed 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 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Iron ore mining and dressing
An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections.
Iron ore crushing and screening process
2. Iron ore screening process: Iron ore screening equipment generally uses a circular vibrating screen to screen the materials after the second crushing. Generally, materials with a size of 10mm or less can be screened for dry selection. After screening, materials with a size of 10-40mm enter the fine crusher for fine crushing.
