Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding the ratio could vary between 1 1and 1.8 1.

Chat Online### Q A Height of ball bounce Department of Physics

The steel ball on an unvarnished pine wood floor may not bounce at all but rather make a dent and so what the floor is made out of makes quite a lot of difference. For multiple bounces it s just like dropping the ball again from a reduced height. If the first height is h the second will be f h the third f f h the fourth f f f h and so on.

The speed of any objects which fall on the earth when it is simply dropped from a certain height is same without any medium (without atmospheric air). So the objects will fall to the ground at the same time.
