Rotary Speed of Ball Mill influence on Grinding .
The rotary speed of ball mill directly determines the state of motion of the cylinder body of the grinding media and grinding operations effects. The lifting height of the balls in the ball mill is small when the speed is low. Because the gravity of the balls themselves, balls fall from the top as spilling off the state.

Ball Mill Critical Speed Mineral Processing .
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed .

Mill (grinding)  Wikipedia
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworks. When I found out that these three simple ...

How I built a quick and easy homemade ball mill
The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a finetoothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on only one side, which were deliberately left loose. This allows the motor to pivot downward under its own weight to put tension ...

Selection Considertions of the Working Speed of .
For this reason, if the workers increase the hoisting height, the working speed of the ball mill should be lower than that using smooth scale board. (2) Mineral hardness and grinding fineness: When roughly grinding the hard and large pieces of rock, you should use larger crushing media and higher working speed, which will be helpful to increase the impacting effect on the materials.
