how much kg of balls can be for kg ore in ball mill

The number of lifters generally can be determined by the rule-of-thumb: Number of Lifters = 3nD for double wave liners. = 6.6D for single wave liners where D is the mill diameter (m). Double wave liners are more suitable for ball sizes less than 60 mm. Otherwise, single wave is preferred.

Ball mills are filled up to40% with steel balls (with30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

2) Ball milling – a ball mill with a diameter of2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.

Based on his work, this formulacanbe derived forballdiameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where Dm = the diameter of the single-sizedballsin mm.d = the diameter of the largest chunks oforein themillfeed in mm.

The FIQ and USBC specify the size and weight of bowlingballs. An adult male bowlingballweighs between 14 to 16 pounds (6.35 to 7.26kg). An adult female bowlingballweighs between 10 to 14 pounds (4.54 to 6.35kg). Bowlingballs canweigh as little as 6 pounds (2.72kg). The heaviest bowlingballsmust not weigh more than 16 pounds (7.26kg).

Jun 15, 2015· A spherical bowlingballwith mass m = 3.3kgand radius R = 0.11 m is thrown down the lane with an initial translational speed of v = 8.9 m/s and no rotational speed. The coefficient of kinetic friction between the slidingballand the ground is μ = 0.28. Once theballbegins to roll without slipping it moves with a constant velocity down the lane.

Poorballsweighed 45.72, averageballsweighed 45.73, goodballsweighed 45.8 and newballsweighed 45.93 on average. If you play poor conditionballs, you could see a weight difference of 3.3 grams from oneballto another.
