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 …
Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to …
To evaluate the primary grinding circuit, four of eight parallel ball mills with their cyclones were selected for sampling. The make-up ball characteristics of each mill are shown in Table 1. In ball mill No.2, 75% 80mm and 25% 60mm balls were charged. The average weight of the balls in each mill is about 300 tons.

In practical terms, one must assume some mill diameter, usually about 150 mm (6 inches) less than the mill inside shell or nominal diameter, that allows for the difference between the mill inside diameter and the location of the centre of gravity of the ball, as well as an assumed liner condition midway between new and fully-worn.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.
