The critical speed of a SAG mill is the speed in RPM's at which centrifugal force causes the material being ground to be held against the inside of the shell. This speed is only dependent on the diameter of the mill.

How do you prevent oxidation in a ball mill?
When setting up a ball mill, it is critical to consider what is being milled. Keeping the mill cool and introducing oxygen scavenging materials will greatly reduce oxidation in a ball mill. Sealing the ball mill production chamber and flushing with nitrogen or an inert gas may help depending on the material that is put through the milling process. Additionally, mill speed must be optimized (not too fast or too slow -- it's critical), and the correct material and size for the balls must be selected.
What are some examples of real life hyperbola?
The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola. Above the critical speed, the orbit will be a hyperbola. (In both cases, the object will go away, never to come back.) Below the critical speed, the orbit is an elipse or a circle.The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola.

What is derivation of critical speed?
Critical speed is the speed in RPM at which a rotating machine will destroy itself by all harmonic vibrations coinciding at maximum vibration.

What are various parts of ball mill?
Ball mill is mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (. And belts are used to transmit rotary motion). Functions on the same principle. , but cannot be used in the preparation of some pyrotechnic mixtures such as. Because of their sensitivity to impact. High-quality ball mill is potentially expensive and can grind mixture particles to as small as 5. , enormously increasing surface is and reaction rates. The grinding works on principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which is responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.if you want more,visit: http://www.zdmill.com/ congratuation to you!
What does it mean by critical speed of a compressor?
It's the speed at which, if exceeded, the compressor will fail.
What is critical speed of pump?
Critical velocity is the speed that a falling object reaches when gravity and air resistance equalize on the object.when a liquid posses streamlined motion and its velocity is less than certain limiting velocity is called critical velocity for fluids and critical velocity for satellites can be defined as the velocity will give stable orbit, this is called the critical velocity for satellites

What is the speed limit in mill creek park in youngstown Ohio?
Most of Mill Creek Park is posted at 15mph. Some places are 20mph.
What is critical speed of steam turbin?
Answer:Turbine shaft material has its own natural frequency, when turbine rotates on such a speed that frequency of shaft become close to its natural frequency, machine causes noise & high vibrations because of resonance due to matching of frequency. Running of Steam "TURBINE" on this speed is avoided & this is called Critical speed. A turbine may have more then one critical speed, which may depend upon number of couplings.A second critical speed is when the Turbine blade tips approach the speed of sound. This effectively limits the speed of a turbine and explains why power plants tend to have turbines of the same capacity.Critical speed of the turbine is the rotor speed at which natural frequency of the assembled rotor (rotor shaft with discs, blades, shrouding strips etc in assembled condition) becomes equal to the operating speed. This is usually a expressed as a range (critical speed range).There are multiple critical speeds. However, the operating speed of the turbine may be above or below the first / lowest critical speed. Accordingly it is called as a flexible or a rigid rotor.Venkatesh
