sag mill critical speed

The SAG mill was designed to treat 2 065 t h −1 of ore at a ball charge of 8 volume total filling of 25 volume and an operating mill speed of 74 of critical. The mill is fitted with 80 mm grates with total grate open area of 7.66 m 2 (Hart et al. 2001).

Planetary Mills – fritsch.de

Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in

Rod mills, how they function

The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the

Sag Mill Overload

Sag mill speed mv2 this variable affects the ore residence time in the mill and, consequently, the other operating variables.The faster the speed, the lower the residence time, enhancing major impacts between particles excess can cause damage to the liners.When the residence time of the ore is higher there is lower pebbles production, but.

SAG is an acronym for semi-autogenous grinding SAG mills are autogenous mills that also use grinding balls like a ball mill A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42' (128m) in diameter, powered by a 28 MW (38,000 HP) motor.

Ball Mills

If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the Critical Speed, and ball mills usually operate at 65% to 75% of the critical speed.

Milling Parameters

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
