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.
The critical speed of a ball mill is determined by the rotation speed of the mill and the diameter of the grinding media. It is calculated using the formula: critical speed = 42.3/sqrt(d), where d is the diameter of the mill in meters. Operating above the critical speed can lead to cascading and ineffective grinding, while operating below can lead to cataracting and unproductive milling.
The critical speed of a grinding mill is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inner surface, leading to no ball fall and higher efficiency. It is calculated by using the formula: critical speed = 42.3/sqrt(D-d), where D is the diameter of the mill in meters and d is the diameter of the grinding media in meters.
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.
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.

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

State A machinery that should be allowed to operate to a critical speed?
Most of Mill Creek Park is posted at 15mph. Some places are 20mph.
SAG
The past tense of sag is sagged.
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!
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
