How Overflow Type Ball Mill Works. Material Feed: The raw material is fed into the mill at one end and travels through the mill by rotation. The feed enters the mill at a specific rate, ensuring a controlled grinding process.; Grinding Process: As the mill rotates, the grinding media crushes and grinds the material into a fine powder. The wet …
